Product Description

 

Product Description

UJK Thrust Ball Bearings - Product Introduction

UJK Thrust Ball Bearings are designed to accommodate axial (thrust) loads only and must not be subjected to any radial load. These bearings consist of two washers (shaft washer and housing washer) and a cage assembly with precision steel balls. Depending on application needs, they are available in single-direction or double-direction configurations.

Engineered with high-grade bearing steel and precision-machined raceways, UJK thrust ball bearings offer smooth axial rotation, minimal friction, and long service life in low to medium-speed applications.

 

Key Features

• Designed for pure axial loads (no radial load support)

• Available in single-direction (one-way axial load) and double-direction (both directions)

• Easy installation and disassembly

• High axial stiffness and running accuracy

• Supplied with or without centering groove

• Optional configurations with sphered seat washers for misalignment compensation

 

Typical Applications

UJK thrust ball bearings are widely used in applications where axial load support is essential, including:

• Machine tool spindles

• Automotive transmissions

• Agricultural and construction machinery

• Textile machinery

• Vertical electric motors

• Rotary tables and lifting mechanisms

• Screw jacks and turntables

2900X	Single	With sphered seat washer	10 - 100	29310, 29412, 29422

 

Note: Series 29XXX (e.g., 29300, 29400) are thrust roller bearings (not ball type), but often used where higher axial capacity is needed.

 

Sample Designation Explanation:

• 51110 = Single-direction thrust ball bearing, bore diameter 50mm

• 52210 = Double-direction thrust ball bearing, bore diameter 50mm

• 29412 = Thrust roller bearing, bore diameter 60mm (for heavier axial load)
