Key Features of ROLLER 8*8
- Precision Dimensions: Manufactured to tight tolerances with an 8mm diameter and 8mm length for uniform load distribution.
- High-Quality Material: Constructed from hardened, high-carbon chromium bearing steel for superior durability and wear resistance.
- High Radial Load Capacity: Designed to support heavy radial loads in compact assemblies.
- Low-Friction Surface: Finely ground surface finish ensures smooth rolling contact, reducing friction and operational temperature.
- Versatile Component: Ideal for use in custom bearing designs, transmissions, universal joints, and as pivot pins.
- Space-Saving Design: The high load-to-size ratio allows for smaller and lighter machinery designs.
Common Applications
- Automotive Transmissions: Used in gear sets and planetary carriers to handle high torque and speed.
- Industrial Gearboxes: Provides reliable support for gears and shafts in heavy-duty machinery.
- Two-Stroke Engines: Commonly found in connecting rods and wrist pin bearings.
- Pumps and Compressors: Acts as a reliable rolling element in various pump and compressor mechanisms.
- Universal Joints (U-Joints): A critical component in the cross assembly of U-joints, enabling torque transmission at an angle.
- Casters and Conveyor Rollers: Used to create durable, free-rolling wheels and rollers for material handling.
- Robotics and Automation: Employed in pivot points and joints where high precision and strength are required.
Benefits of Using ROLLER 8*8
- Enhanced Load Capability: The cylindrical shape provides a larger contact area, enabling higher load support than ball bearings of a similar size.
- Increased Rigidity: Offers high stiffness, which is crucial for applications requiring precise shaft alignment and minimal deflection.
- Reduced Maintenance: Durable construction and low wear characteristics lead to longer service intervals and reduced costs.
- Design Flexibility: Allows for the creation of custom bearing solutions tailored to specific application requirements without a full outer or inner ring.
- Improved Equipment Lifespan: Reduces friction and wear on mating parts, extending the overall operational life of the machinery.
- Cost-Effective Solution: An economical choice for high-volume production and for repairing specific bearing assemblies instead of replacing the entire unit.
