Design Features of 2305 M Bearing

2305 M Bearing is a type of rolling-element bearing uniquely desi

gned to tolerate misalignment of the shaft with respect to the housing. It has two rows of balls and a common spherical raceway in the outer ring, allowing the bearing to be self-aligning. 2305 M bore dia is 25 mm. Its out dia is 62 mm. Its width is 24 mm. 2305 M Bearing is versatile and adaptive, ensuring smooth operation even when not perfectly aligned. Its unique design helps prevent stresses on the bearing, resulting in a longer operational life.

What Benefits Can 2305 M Bearing Provide?

Misalignment Adaptability: These bearings efficiently handle both static and dynamic misalignment, resembling the self-aligning capabilities of spherical roller bearings.

High-Speed Efficiency: With reduced friction compared to other bearings, they remain cool, even at elevated speeds.

Longevity and Low Maintenance: Their ability to run cooler means longer bearing life and fewer maintenance breaks.

Optimized for Light Loads: They operate exceptionally well, even under minimal load conditions.

Noise and Vibration Reduction: Ideal for applications like fans, these bearings help in decreasing noise and vibration levels.

What Can 2305 M Bearing Be Used for?

2305 M Bearing is suitable for applications where misalignment can arise from errors in mounting or from shaft deflection.

Automotive: Used in power steering systems, drive shafts, and steering column joints, where angular misalignments are common.

Agricultural: Essential in farm equipment like tractors and harvesters, where uneven terrains can cause shaft misalignment.

Textile: Deployed in spinning and weaving machines where smooth, consistent rotation is crucial.

Conveyor Systems: Useful in belt systems to maintain consistent belt tension and alignment, especially in long-distance conveyors.

Mining and Double Row: Used in crushers, vibrating screens, and heavy-duty machinery that undergo rigorous operation and potential shaft deflections.
