Product Description

The 51102 MGK 15x28x9 mm thrust ball bearing is a precision-engineered component designed to handle axial (thrust) loads in various industrial applications.
Unlike radial bearings, it is built specifically to support loads acting along the shaft’s axis, ensuring stable operation, precise alignment, and minimal axial play.

Manufactured from high-grade bearing steel, the 51102 MGK offers high durability, smooth rotation, and resistance to fatigue under continuous use. Its compact design allows easy installation in bearing housings or bearing units, providing dependable axial support even in limited spaces.

Commonly used in motors, gear assemblies, conveyors, and automation machinery, it improves system reliability by reducing vibration and preventing excessive wear on connected components.
As part of a complete industrial bearing assembly, this thrust ball bearing contributes to longer maintenance intervals and lower operational costs — key priorities in industrial operations.

FAQ

Q1: What is the main function of the 51102 MGK bearing?
A1: It transmits axial loads (thrust forces) along the shaft, preventing unwanted axial movement and stabilizing mechanical systems.

Q2: Can this bearing handle radial loads?
A2: No - thrust ball bearings are designed specifically for axial loads only. For radial loads, a deep groove or angular contact ball bearing should be used.

Q3: Are the dimensions 15x28x9 mm standardized?
A3: Yes, this is a standard size widely used in industrial bearing housings and units, ensuring compatibility and quick replacement.

Q4: In what applications is this bearing commonly used?
A4: It’s ideal for industrial drives, automation systems, gearboxes, motors, and bearing housings where axial support is required.

Q5: What benefits does it provide in bearing units?
A5: It improves operational stability, reduces wear, and extends service life by maintaining accurate axial positioning of the shaft.
