Description:
- Needle Roller Thrust Bearings provide a high degree of stiffness within a minimum axial space. It has a smaller cross-section than a standard thrust bearing for use in restricted spaces.
- These bearings to accommodate heavy axial loads and peak loads due to small diameter deviation of the rollers within one assembly.
- AXK Thrust Bearings can be combined with washers in the AS series in applications where adjacent components cannot serve as raceways.
- Made of hardened spring steel, both faces of the washers are polished and can be used as raceways.
- Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.

Great price and very good quality. I purchased these to improve the feel of my metal lathe hand cranks.

These thrust bearing worked as it should

Used on top of my quick change tool post to make the clamp on top hold better and release easier. Applied a small amount of moly grease to needle bearings before installing. Now I need to find uses for the rest of the bearings in the bag.

As expected.

Does what they're supposed to do.

Don’t know how they will hold up but for what I am using them for they work fine. Using them to eliminate backlash on a drill press vice.

The bearings appear to be of acceptable quality for hobby projects. I would not recommend for precision needs.

Roller thrust bearings operate over a wide radius (vs ball type), and therefore the needle rollers need to be tapered: Smaller radius on the inside, larger radius outside. That also means the washers are conical to properly fit the needles, making the whole apparatus an efficient thrust bearing.NOT HERE!The rollers are a uniform diameter, and the washers are flat, which means the bearings are dragging rather than rolling, and often translating the thrust load to a lateral load on the washers. If you're using these for a fidget toy, fine. If you're looking for proper thrust roller bearings, spend an extra buck or two and get the real deal.

Excellent quality and perfect for my needs. I just haven’t used them yet !! Many thanks…..
