Balls
A bearing SN517 contains five steel balls that move between two circles known as the outer and inner race. Deep groove ball bearings are the most common type as they can support radial and axial loads. They are widely applied because they have low friction, need little maintenance, and can function at high temperatures. The steel balls allow the parts to rotate with ease and stability. This kind of ball bearing is mostly used in electric motors, gearboxes, and pumps.
Cylindrical rollers
The CN bearing features cylindrical rollers that sit between the inner and outer rings. These roll-shaped elements help spread the load across a wider area compared to ball bearings. Because of this, cylindrical roller bearings are ideal for always supporting heavy radial loads and are most commonly used in machinery with large parts, such as motors and industrial machines.
Tapered rollers
A Taper bearing is made up of cone-shaped rollers that sit between two metal parts, the inner race and outer race. Its unique cone shape allows it to smoothly and precisely manage both radial and axial loads. It is ideal for applications with big sideways (thrust) and straight (radial) loads, such as gears and wheels. Trucks and construction tools often use tapered roller bearings in their front wheel hubs.
Needle rollers
The SNR 517 uses slim, cylindrical rollers called needle rollers. These rollers are compact and great at handling heavy radial loads. Their tight shape allows them to fit in small spaces while still distributing the load across a large surface area. It is often used in machinery where there isn't much room but needs to bear a heavy load, such as in construction equipment or pumps.
Automotive and transport sector
The T bearing is often used in vehicles and automotive parts, such as wheel hubs, transmissions, and differentials. Other places include light, medium, and heavy trucks, as well as buses and trailers. It provides support and reduces friction in rotating components. Basically, anywhere in the transportation industry it is crucial for people to keep maintenance costs down while also making sure they stay on the road and their machinery doesn't break, the SN517 bearing is used.
Industrial machinery and equipment
The SN517 is broadly applied in industrial machinery. This includes motors, conveyors, pumps, fans, and various equipment used in manufacturing processes. With its ability to support heavy loads and endure tough working environments, the bearing is ideal for enhancing operational efficiency and longevity in constant use within factories and industrial settings.
Aerospace and defence
The bearing can be found in different aerospace and defence applications. Examples include turbines, generators, gears, and other flight-related or space hardware. The SN517 is built to function reliably under extreme conditions, one of the reasons it is ideal for reliable performance in critical aerospace applications where failure simply is not an option.
Construction and farming equipment
The Bearing SN517 is used in construction and farming equipment, such as excavators, tractors, and more. These are all the large mechanical equipment with rotating parts. In these industries, the bearing helps to ensure that heavy loads are borne while at the same time allowing for smooth and flexible movements. This prolongs the life of the equipment. It also reduces downtime in operation.
Home appliances and consumer goods
SN 517 can commonly be found in everyday household items, including washing machines, fans, air conditioners, and even power tools. These are all the small mechanical parts. It plays a major role in cutting down friction, noise, and wear and tear in those appliances. This improves the quality and durability of those products as well as their effectiveness.
Dimensional specifications
The SN517 has an inside diameter of 85 millimetres and an outer diameter of 150 millimetres. Its width is 45 millimetres. This means the bearing's inner circle has a space of 85 millimetres wide for a shaft to fit into, while the outer circle is 150 millimetres wide. The bearing is 45 millimetres thick.
Load specifications
The SN517 can handle a maximum static load of 71 kilonewtons and a maximum dynamic load of 84 kilonewtons. Kilonewtons are a measure of force. These values mean the bearing can support heavy weights and withstand moving pressure without crushing the metal too thin.
Speed specifications
The maximum speed is up to 1,500 revolutions per minute for greased conditions and up to 2,500 rpm for oil conditions. This means how fast the bearing can rotate while still working safely with either lubricant.
Other specifications
The SN517 has two rubber seals on both sides that protect the insides from dirt and help keep the lubricating grease inside. It uses a special type of grease called lithium soap to lubricate and prevent rust. Lithium soap grease is long-lasting and good at reducing friction.
Type of bearing
The SN517 is a deep groove ball bearing which is versatile and mostly used. It is suited for both radial loads that push perpendicular to the axis of rotation and axial loads which are parallel and push in one direction. This is because of its unique shape and structure.
Material
High-quality steel or chrome alloy steel is typically used to manufacture bearings. Bearings are often made using this tough metal. It has great tensile strength. So, it can withstand gradually increasing pulling forces. This durable steel is also corrosion-resistant to prevent rusting from moisture and other environmental elements.
Durability
The SN517 is designed to be extremely long-lasting. It is made from hardy materials that withstand wear and tear from constant motion and heavy loads over time. Its seals help keep lubricants inside and block contaminants. This increases its lifespan in tough operating conditions.
Low friction
The ball bearings inside glide with very little resistance or friction compared to other types like rollers. This ultra-smooth motion uses less energy and generates less heat as the parts move. It prolongs equipment life and allows for more efficient operation in one place or multiple machines.
Versatility
Due to its features, the SN517 can be applied in many settings, whether light or heavy. It can work in home appliances, automotive, industrial machinery, and commercial and agricultural equipment. It is one of the most versatile bearings available.
Compatibility with equipment
Buyers have to ensure that the SN517 bearing is compatible with the parts of their machinery where they will install it. They should refer to the manufacturer's recommendations on the type of bearing that should be used. They should also check whether other similar models would work for their equipment. If they are not sure, they can seek advice from professionals. They should also consider the maintenance requirements of the SN517 and if they can meet them.
Operating conditions
The SN517 should be suitable for the conditions in which the bearing will operate. Buyers should consider factors such as the load type and size, the speed at which the equipment moves, and the environment's temperature and level of dirt or moisture. There are specialists that can help choose the right Bearing SN517 for the operating conditions.
Quality and brand reputation
The quality of the bearing can directly impact the bearing's strength and how long it will last, as well as the effectiveness of the equipment. Buyers should pick bearings from reputable manufacturers. They should also look for the umber of reviews and ratings. They also need to consider the Sn517's seal and shield options. These are key for contamination protection. Some may be better suited for harsh environments than others.
Budget
SN517 bearings are available at different prices. Sometimes, the price can be an indicator of its quality. But not all. Buyers should get bearings that fit their budget but bear in mind the more the bearing costs, the stronger and longer-lasting it will be. They should also consider the long-term savings. A higher priced quality bearing that lasts longer with less need for replacement or maintenance may be worth more than a cheaper bearing that wears out more frequently.
A1.The average or expected life of a Bearing SN517 can vary quite a lot based on the specific conditions it's used in. How heavy the loads are, what speed the equipment operates at, and the environment all affect how long the bearing will last. With proper care and maintenance, the SN517 can last several thousand hours of use. In really tough conditions - like very high or low temperatures, lots of dirt or moisture, and extremely heavy loads - the bearing may wear out sooner, maybe a few hundred or thousand hours. But if the SN517 is used under normal conditions with the right lubricants and care, it could last up to 5,000 hours or more.")
A2.Different types of lubricant are recommended for the skf sn517 to protect it and have it last longer. Lithium grease is one of the best lubricants. The SN517 comes sealed, which means it has grease in it already that will last a long time. For really harsh conditions, like extreme temperatures or dirt, special types of oils are good, too. Regularly checking and replacing the lubricant helps the bearing work better and last longer.
A3. Yes, the Bearing SN517 can handle both very high and very low temperatures. The heat limit it can stand is about 120 degrees celsius. On the other end, it can manage cold down to -40 degrees celsius. When going beyond these temperature ranges, it's best to check what kind of lubricant to use. The right lubricant for the temperature is key to having the SN517 work perfectly in extreme environments.
A4. The NEUTRAL BEARING SN517 comes with both a seal and a shield on each side. The difference between the two is that a seal is a rubber ring that tightens the space between the moving parts to stop gunk from getting in and grease from leaking out. A shield is a flat piece of metal that blocks dirt but doesn't hold grease as well. But the Bearing SN517 also has seals that do the important job of keeping the lubricating grease inside and contaminants out, especially in crunchy conditions.
A5.The bearing 517 is normally made from durable steel. Sometimes, it may be steel alloys with other metals like chrome. These strong materials help the bearing handle heavy weights. Steel alloys are paradise for the Bearing SN517, as it is tough, can be easily machined, and stays rust-resistant for a long time. Rust is the enemy that ruins bearings. The inner and outer rings, as well as the ball, are made from this hard material. Some SN517 bearings have balls made from ceramics for special uses.
