Detailed Applications

Key Industrial Uses

  • Machine Tool Spindles: Supports high-speed rotational accuracy in CNC lathes and milling machines.
  • Gearboxes: Reduces friction and axial displacement in heavy-duty transmissions.
  • Robotic Arms: Enhances positioning precision in automated manufacturing systems.

Usage Scenarios

Scenario 1: Precision Machining Centers

In CNC machining centers, the 17716 bearing minimizes vibration during high-speed operations, ensuring surface finish quality ≤0.8μm Ra.

Scenario 2: Heavy-Duty Lathes

Used in vertical turning lathes, it sustains radial loads up to 280kN, extending service life by 40% compared to conventional bearings.

Client Case Studies

Case Study 1: XYZ Precision Machinery Co., Ltd.

  • Challenge: Frequent bearing failures in CNC grinders due to thermal expansion.
  • Solution: Upgraded to 17716 bearings with optimized thermal stability.
  • Result: Downtime reduced by 62%; operational temperature stabilized at 65°C.

Case Study 2: ABC Heavy Industries

  • Challenge: Axial displacement in gearboxes caused misalignment.
  • Solution: Installed 17720 series bearings with double-row taper design.
  • Result: Gearbox efficiency improved by 28%; maintenance intervals extended to 12 months.
