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.
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
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

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