How to choose Rolling Bearings
Points to check when selecting, with the values for this product (Centering Flange Thrust Needle Roller Bearing AXW Series).
-
1. Bore and housing bore dimensions
This product: Inner diameter d 10~50 mmSelect the bore diameter d to match the shaft seat, the outside diameter D to match the housing bore, and the width B to suit the installation space. Main dimensions are standardized in ISO and JIS dimension series, so interchangeable products can be found by boundary dimension designation. For tapered roller bearings, also check the assembled width T; for thrust bearings, also check the height H.
-
2. Dynamic load rating based on life calculation
The basic dynamic load rating Cr is the reference value for calculating rated life. Verify that the required life is met using the equivalent load during operation and the rotational speed. For ball bearings, life is proportional to the cube of the load ratio, so providing load margin greatly extends life.
-
3. Margin for static and shock loads
The basic static load rating C0r is the allowable standard for permanent deformation generated at the rolling elements and raceways under stationary or low-speed conditions. For applications with oscillating motion or shock loads, confirm that a static safety factor against the maximum load is secured using C0r.
-
4. Operating speed and lubrication method
The limiting speed differs by lubrication method, and separate values are given for grease lubrication and oil lubrication. Confirm that the normal operating speed does not exceed the limiting value, and in high-speed ranges also consider cage material and precision grade. The reference speed can also be consulted as a thermal guideline.
-
5. Precision grade and internal clearance
Precision grades (P0, P6, P5, etc.) indicate rotational accuracy and dimensional accuracy; for high-precision applications such as machine tool spindles, select higher grades. Internal clearance (C2, CN, C3, etc.) is selected to allow for changes caused by interference fit and temperature differences during operation.
-
6. Materials and lubrication suited to the environment
For corrosive, high-temperature, vacuum, or clean environments, select specifications such as rings and rolling elements made of stainless steel or ceramics, or solid lubricants and fluorine grease for vacuum use. Check the operating temperature range, low dust generation, and whether food-grade grease registration applies against the application conditions.

Description
Consists of needle rollers with a thrust cage and a centering race washer. Easy to install, and enables accurate radial centering of the housing race washer. Can be combined with shell-type or solid-type radial needle roller bearings to accommodate combined loads. The cage is made of steel.
Features
- Centering flange for easy installation
- Accurate radial centering of the housing race washer
- Accommodates combined loads when combined with radial needle roller bearings
- Steel cage
FAQ
- Q. Which size range and load direction can the AXW Series centering flange thrust needle roller bearing be used for?
- A. It is a centering flange thrust needle roller bearing with shaft diameter 10 to 50 mm. It carries axial load in one direction.
- Q. Can the AXW Series also accommodate radial or combined loads?
