Thrust Ball Bearing

Thrust ball bearings are used to boost mechanical efficiency by lowering friction. A correct bearing installation is essential to get the most out of your equipment. Inadequate industrial bearings can reduce efficiency, increase maintenance requirements and make it more expensive to fix equipment failure.

Dynamic load and static load specifications are important to understand when choosing thrust bearings. These values help determine the expected bearing lifespan.

Balls

Thrust ball bearings use rolling elements (balls) to support a predominately axial load. This creates low friction in a bearing. These elements are supported between precision chrome steel washers, or rings that are spaced by a retainer. The thrust bearing must be lubricated to perform at it’s rated dynamic capacity.

These bearings can be either open-style or sealed. The sealed variety have metal shields that are pressed onto one or both sides of the outer rings. This prevents dirt or debris from contacting the inner raceways.

These shields can also be removable to access the inner raceways for inspection and cleaning. This allows the bearing to be maintained and relubricated as needed. The thrust bearings can be single direction or double direction. The latter can handle axial loads in both directions, but cannot bear any radial load. The angular thrust bearing can handle the same axial loads in either direction, but can also support a percentage of radial load.

Races

Thrust bearings are used to support axial loads. They can either be one-way bearings that limit the axial displacement of the shaft in a single direction, or two-way bearings that limit the axial load in both directions.

They can withstand high loads and are very durable. However, the lifespan of a thrust ball bearing can be affected by many factors including the maximum dynamic load, operating speed, and ambient temperature.

Several types of thrust ball bearings are available, including full complement designs and self-aligning bearings. Full complement thrust bearings are designed with more balls between the races and can handle higher axial loads. These types of bearings are often used in heavy-duty machinery, such as drills and cranes.

Self-aligning thrust ball bearings have a larger race on one side that allows it to seat into an unstepped shaft bore. The other race has an identical bore and requires a stepped shaft to fit into it.

Cage

Bearings are an essential part of many machines, limiting the movement of moving parts and decreasing friction. They come in various types to suit different applications. One such type is the thrust ball bearing, which is designed to support axial loads while operating at high speeds.

Thrust ball bearings are composed of a washer-like ring with raceway grooves for the balls. They are able to take thrust loads while operating at high speeds but cannot sustain radial loads. They are available in single direction and double direction designs, with the latter able to take axial loads from both directions.

These self-aligning bearings are suited for heavy axial loads and can tolerate angular misalignments. They are also suitable for combined axial and radial loads. They are available in both solid shaft locating and housing locating versions. They are supplied with solid cages made of brass or steel, depending on the application. They are lubricated with oil or grease.

Bearing Centre

Sanjay Bearings is the leading provider of Thrust Ball Bearings across India. They have a clear focus on Total Dedication, Total Commitment and Total Quality. This enables them to deliver world class products at competitive prices to their customers.

They offer a wide range of ball sizes for each type of thrust bearing. Choosing the right size can help you reduce friction. You can also select premium balls made of stainless steel or glass to ensure performance and durability.

Cylindrical roller thrust bearings can handle heavy axial loads and are stiff, oblivious to shock loads, and require little space. However, they cannot carry radial loads. To compensate for this, they are often equipped with spherical aligning seats on the shaft and housing washers to reduce misalignment. This feature makes them a good choice for applications that encounter high speeds or heavy loads. They are also heat treated, which improves their thermal tolerance and extends their lifespan.
