Types of Needle Roller Bearings
Drawn Cup Needle Roller Bearings
- 2 types: open type and closed-end type.
- They have no inner ring, the needle roller is in direct contact with the shaft surface.
- With cage are suitable for high speed and heavy load, mostly used in machine tool gearbox or textile machinery.
- Without cage are equipped with full needle rollers and are suitable for oscillating working conditions under heavy load.
Needle Roller Bearings with Machined Rings
- Made of chrome steel, with or without inner ring.
- It has the advantage of small radial cross-sectional dimensions and carries a high radial load.
- It has a cage, so it has a higher speed and can adapt to the requirements of the gearbox.
Needle Roller and Cage Assemblies
- Bearings with high load carrying capacity and high stiffness, compact bearing construction in which the assembly shaft and bearing housing bore can be used as raceways.

I gave this a mid rating because I could not use them. The important thing to know is the "One Way Bearing'. This means they will only operate in one direction. If you try and turn these in the opposite direction of 'normal', it will lock up. I needed the bearing to operate in both directions. At least I learned of this distinction.

I have been using these on the machines I service for about 2 years now, and have installed hundreds of them over that time. I have never had any issue with them allowing any slop to occur, they just do their job and and seem to last just as long as the name brand one way bearings.

I used these bearings as part of a Buddhist prayer wheel installation so it was important to have a bearing that would allow the prayer wheel to spin a sufficient length of time. These bearings did that.

Mounted in a piece of wood and secured it with epoxy. Hold 1/4" router bit shaft so the bearing secure not can be removed easily.

Bought these to make some aluminium tool handles for deburring and countersinking. These work very well. Pressed into holes undersized by 0.001" and they hold the bits very well without slippage.
