MGK 6309 Deep Groove Ball Bearing 45x100x25

Overview

The MGK 6309 is a single row deep groove ball bearing designed for industrial applications requiring high radial load capacity, smooth operation and reliable performance. Its open design allows external lubrication, making it suitable for equipment equipped with centralized lubrication systems or applications where lubricant type and maintenance intervals are controlled by the machine manufacturer. The bearing supports both radial loads and moderate axial loads in either direction.

Industrial Applications

The bearing is widely used in electric motors, industrial gearboxes, centrifugal pumps, compressors, conveyor systems, agricultural machinery, construction equipment, industrial fans, machine tools and OEM power transmission systems. It is intended for continuous-duty applications where open bearings provide optimal lubrication flexibility.

Construction

The 6309 incorporates precision-ground inner and outer raceways, hardened steel balls and a pressed steel cage. The open construction enables efficient lubricant circulation and heat dissipation while maintaining low rolling resistance and stable performance under continuous operating conditions.

Material

The rings and rolling elements are manufactured from premium through-hardened bearing steel with excellent fatigue strength, wear resistance and dimensional stability. Precision heat treatment ensures reliable performance under heavy radial loads and prolonged industrial operation.
