Thrust Angular Contact Ball Bearing：5692/800 (Old Model: 91682/800)

Description

Product Overview

The FODA Bearing model 5692/800 (old code 91682/800) is a large-size thrust angular contact ball bearing with a bore of 800 mm, an outer diameter of 1060 mm, and a width of 155 mm. Each unit weighs approximately 293 kg. Manufactured from premium high-carbon chromium bearing steel (GCr15) and processed through precision grinding and heat treatment, it offers exceptional load capacity, wear resistance, and long service life. The standard contact angle is 60°, with precision grades P5 or P6 and customized configurations available upon request.

 

Performance Features

• High Load Capacity & Long Service Life:
  The optimized raceway geometry ensures balanced load distribution, allowing the bearing to withstand heavy axial forces of several thousand kilonewtons. Reinforced steel and high-purity grease extend operational life significantly.

• Excellent Rigidity & Precision:
  Advanced grinding and assembly processes provide low runout and high stiffness, making it ideal for precision rotary tables, spindles, and drilling systems.

• Impact & Heat Resistance:
  Special heat-treatment technology enables reliable operation under high temperatures, heavy loads, or shock conditions.

• Smooth and Quiet Operation:
  Reduced vibration and friction through optimized ball arrangement and lubrication paths ensure smooth, quiet running.

• Easy Installation & Maintenance:
  Optional designs with lubrication holes, grooves, and seals make installation and servicing more convenient in demanding environments.

• Custom Engineering Solutions:
  Available in non-standard sizes, corrosion-resistant materials, high-temperature lubricants, and special sealing structures tailored to customer applications.

Product Applications

The 5692/800 thrust angular contact ball bearing is ideal for heavy-duty applications that demand high axial load capacity, low rotational speed, and exceptional rigidity and precision — particularly in the oilfield and energy sectors.

• Oil Drilling Rigs & Rotary Tables: Provides stable axial support for continuous, high-torque drilling operations.

• Mud Pumps & Oilfield Pumping Systems: Designed to endure high vibration and axial thrust, extending maintenance intervals in harsh oilfield conditions.

• Offshore Drilling & Extraction Platforms: Corrosion- and temperature-resistant, suitable for marine, high-salt, and high-load environments.

• Large CNC and Vertical Lathe Spindles: Ensures machining precision and spindle stability during heavy cutting operations.

• Metallurgical Rolling Mills: Operates reliably under long-duration, high-load conditions with outstanding fatigue resistance.

• Wind Energy Equipment: Performs smoothly under slow-speed, high-thrust operating conditions.

• Mining and Construction Machinery: Provides robust support for rotary drives and heavy-duty transmission systems.
