Deep Groove Ball Bearings

PMK Deep Groove Ball Bearings are versatile, high-precision bearings engineered for smooth rotation, low noise, and long service life under radial and moderate axial loads. They are the most widely used bearing type, supporting efficient operation across diverse mechanical systems.

Designed with optimized raceway geometry and premium-grade steel balls, PMK bearings deliver consistent performance in both high-speed and heavy-duty applications. Their compact construction, combined with low friction and precision clearances, ensures excellent reliability across industrial and automotive sectors.

Key benefits

High versatility: suitable for radial and bidirectional axial loads in both low and high-speed applications.
Low noise and vibration: precision raceways and optimized internal geometry reduce friction for smooth, quiet operation.
Long service life: high-quality steel, controlled hardness, and superior surface finish minimize wear and extend bearing life.
Ease of mounting: simple design allows for easy installation and interchangeability.
Available types: open, sealed, and shielded versions to suit varied environmental conditions.
High-speed capability: engineered for reliable performance in high-speed machinery and precision equipment.

Applications

Electric motors and generators.
Industrial gearboxes and transmission systems.
Automotive components, pumps, and compressors.
Machine tools, conveyors, and general machinery.
Household and agricultural equipment requiring smooth, efficient motion.
