Shielded Bearings

Working Principle

The shielded bearings operate based on the principle of rolling elements, such as balls or rollers, fitting within inner and outer rings. These elements reduce friction by rolling instead of sliding, enabling smooth and efficient rotation.


The shielded bearings find wide applications in various industries, including:

  • Automotive: Used in car engines, transmissions, and wheel hubs.
  • Industrial Machinery: Applied in pumps, motors, conveyors, and robotics.
  • Medical Equipment: Utilized in dental tools, surgical devices, and imaging systems.
  • Electronics: Found in printers, scanners, and computer disk drives.

Application Scene

What are Shielded Bearings?

Shielded bearings, including the MR52ZZ Deep Groove Ball Bearing, have protective shields or seals on one or both sides. These shields prevent contaminants from entering the bearing and retain the lubricant inside, ensuring smooth operation and prolonging the bearing's life.

Why Use Shielded Bearings?

Shielded bearings provide several benefits, including:

  • Protection against contamination, dust, and debris.
  • Improved lubrication retention for long-lasting performance.
  • Reduced maintenance requirements and downtime.
  • Enhanced reliability and efficiency of rotating equipment.

Types of Shielded Bearings

Shielded bearings come in various types, including:

  • Deep Groove Ball Bearings: Suitable for high-speed and radial load applications.
  • Angular Contact Ball Bearings: Designed for combined axial and radial loads.
  • Self-Aligning Ball Bearings: Can accommodate misalignment and shaft deflection.
  • Thrust Ball Bearings: Designed to handle axial loads in a single direction.
  • Cylindrical Roller Bearings: Ideal for heavy radial loads and high-speed applications.

Choosing and Using Shielded Bearings

To select and use shielded bearings correctly:

  • Consider the specific requirements of your application, such as load capacity and operating conditions.
  • Choose the appropriate bearing size and type based on the equipment's design and specifications.
  • Ensure proper installation and alignment to prevent premature wear and damage.
  • Follow recommended maintenance practices, including regular lubrication and inspection.
