6205 Open Deep Groove Ball Bearing, P0 Precision, ABEC-1 Grade, 25x52x15mm, for

The 6205 Open Deep Groove Ball Bearing is a single-row, non-separable bearing designed for high-speed operation with minimal friction and low maintenance.

With bore diameter 25mm, outer diameter 52mm, and width 15mm, it fits a wide range of standard industrial housings and shafts.

Its open design allows for easy relubrication, making it ideal for applications where regular grease replenishment is part of the maintenance routine.

High-Speed Capable. Precision-honed raceways and uniform ball geometry reduce friction, allowing smooth rotation at elevated speeds without excessive heat buildup.

Low Noise Operation. Available in noise grades Z1 through Z4, with vibration levels V1 through V4, meeting the strictest requirements for electric motors and quiet-running equipment.

Multiple Material Options. Standard bearing steel (GCr15) for general industrial use. Stainless steel for corrosive environments. Ceramic (Si3N4) for extreme speed or electrical insulation needs.

Precision Flexibility. Produced in P0, P6, P5, and P4 tolerance grades, covering everything from standard agricultural machinery to high-precision machine tool spindles.

Wide Lubrication Compatibility. Open design accepts both grease and oil lubrication systems. Compatible with standard lithium, polyurea, and high-temperature synthetic greases.

Easy Installation. Non-separable construction prevents assembly errors. Standard dimensional tolerances ensure drop-in compatibility with ISO housings worldwide.

The bearing features a pressed steel cage that securely spaces the balls while allowing efficient lubricant flow through the bearing.

Deep, continuous raceway grooves in both inner and outer rings provide a precise ball path, minimizing skidding and ensuring even load distribution across all rolling elements.

Super-finished ball surfaces (Grade 10 or better) reduce surface roughness, directly translating to quieter operation and extended grease life in service.
