Design Features of QJ 324 N2MA Bearing

QJ 324 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 324 N2MA bore dia is 120 mm. Its out dia is 260 mm. QJ 324 N2MA width is 55 mm. It provides a balance of load handling, space utilization, and performance.

 

What Benefits Can QJ 324 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.
  • Precision and Stability: Offers high precision and stability in operation, essential for applications requiring accurate rotational movement.
  • Space Efficiency: Ideal for applications with limited space, delivering robust performance without the need for larger bearing arrangements.

 

What Can QJ 324 N2MA Bearing Be Used for?

QJ 324 N2MA Bearing is utilized in applications that demand robust axial and radial load support within a compact design. Key uses include:

  • Turntables and Indexing Tables: For precise and stable rotation under combined loads.
