Design Features of QJ 1272 N2MA Bearing
QJ 1272 N2MA Bearing is characterized by a unique design where a single row of balls engages with four points of contact on the raceways (two inner and two outer points). This configuration forms an angular contact that allows the bearing to support axial loads from both directions. QJ 1272 N2MA bore dia is 360 mm. Its out dia is 650 mm. QJ 1272 N2MA width is 122 mm. It provides a balance of load handling, space utilization, and performance.
What Benefits Can QJ 1272 N2MA Bearing Provide?
- Axial Load Handling: Capable of supporting significant axial loads in both directions, ideal for applications requiring bidirectional axial load support.
