Core Type: RAX

• RAX bearings are combined radial and axial bearings.
• The radial load is handled by a needle roller bearing.
• The axial load is supported by a thrust ball bearing.
• Typically used when axial load acts in one direction only.

Suffix Meanings

Let’s unpack the common suffixes:

RAFX

• Same as RAX, but with a flanged outer ring.
• The flange helps with axial location in the housing.
• Easier to mount and more secure axially.

RAXN

• Needle + thrust ball bearing without inner ring.
• Designed to run directly on the shaft (shaft must be hardened and ground).
• Saves space but requires precise shaft preparation.

RAXZ

• RAX with a metal shield or seal on the thrust side.
• Protects the axial bearing from contamination and retains lubrication.

RAXPZ

• Like RAXZ, but with improved sealing or higher-performance materials.
• Often used in more demanding environments.

RAXNZ

• Similar to RAXN (no inner ring) but with seal/shield on thrust side.
• Combines compact shaft mounting with basic sealing.

RAXNZPZ

• Most complete version:
  • No inner ring (runs on shaft)
  • Sealed or shielded
  • Often a premium version for compact, protected applications

Quick Comparison Table

Applications

These bearings are ideal for:

• Machine tools
• Packaging equipment
• Compact actuators
• Textile machines
• General machinery where both radial and axial loads must be supported in a small space
