Design Features of QJ 317 N2MA Bearing
QJ 317 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 317 N2MA bore dia is 85 mm. Its out dia is 180 mm. QJ 317 N2MA width is 41 mm. It provides a balance of load handling, space utilization, and performance.
What Benefits Can QJ 317 N2MA Bearing Provide?
- Axial Load Handling: Capable of supporting significant axial loads in both directions, ideal for applications requiring bidirectional axial load support.
- Compact Design: Combines the functionality of double-row bearings in a more compact form, saving space in assembly.
- Radial Load Capacity: Efficiently handles radial loads, providing versatility in various mechanical setups.
