Thrust Cage-Type Needle Roller Bearing AXK Series

AXK / SKF (Official website) / Listed on page 6 of the document

Thrust needle roller bearings with shaft diameter 4 to 80 mm (outer diameter 14 to 105 mm). The cage securely retains the needle rollers, supporting heavy axial loads and shock loads. Axial load can be applied in one direction only.

How to choose Rolling Bearings

Points to check when selecting, with the values for this product (Thrust Cage-Type Needle Roller Bearing AXK Series).

  1. 1. Bore and housing bore dimensions

    This product: Inner diameter d 4~80 mm

    Select 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. 2. Dynamic load rating based on life calculation

    This product: Basic dynamic load rating Cr 4.15~51 kN

    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. 3. Margin for static and shock loads

    This product: Basic static load rating C0r 8.3~280 kN

    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. 4. Operating speed and lubrication method

    This product: Limiting speed (grease lubrication) 3400~15000 r/min

    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. 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. 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.

About Rolling Bearings and all products

Description

Multiple needle rollers are guided by a cage with excellent shape stability. The roller diameter variation is minimal, and both ends of the roller rolling surface have slight curvature to reduce peak edge stress. When adjacent components cannot serve as raceways, combine with LS, AS, or GS/WS 811 Series raceway washers. A resin cage (TN) specification is also available. Installation requires observing the shaft and housing support surface dimensions (Ea/Eb).

Features

  • Cage with high shape stability
  • Minimal roller diameter dimensional variation
  • Roller end curvature reduces peak stress
  • High rigidity with minimal axial space
  • Axial load can be applied in one direction only

FAQ

A. The bore diameter d is 4 to 80 mm, and the outer diameter D is 14 to 105 mm.
Q. What are the load rating and speed ranges of the AXK Series?
A. The basic dynamic load rating Cr is 4.15 to 51 kN, and the basic static load rating C0r is 8.3 to 280 kN. The reference speed is 1700 to 7500 r/min, and the limiting speed (grease lubrication) is 3400 to 15000 r/min.
Q. What should be used with the AXK Series when adjacent components cannot serve as raceways?
A. Combine it with LS, AS, or GS/WS 811 Series raceway washers.
Q. What are the cage features of the AXK Series, and is a resin cage specification available?
A. It uses a cage with excellent shape stability to guide many needle rollers. A resin cage (TN) specification is also available.
