Custom R Series Deep Groove Ball Bearing Manufacturers, Factory

R Series

R Series Deep Groove Ball Bearing is a widely used bearing type. It has the characteristics of simple structure, easy installation and low maintenance cost. It can withstand radial load and certain bidirectional axial load. In addition, R series deep groove ball bearings also have the characteristics of low friction, low noise and low vibration, and are suitable for high-speed operation conditions. This kind of bearing provides a variety of structural types, such as with dust cover, sealing ring, etc., to meet the needs of different working environments.

R Series Deep Groove Ball Bearing

inch / metric bore open / shielded / sealed P0 / P5 precision

Compact footprint

Designed for applications with limited space, the R series provides reliable radial and axial load support within a minimal envelope.

Inch and metric variants

Available with standard inch bore sizes (R4, R6, R8 etc.) as well as metric equivalents for interchangeability with existing designs.

Sealing configurations

Open, metal shielded (ZZ), or rubber sealed (2RS) variants available to meet specific contamination and lubrication requirements.

Smooth operation

Precision-ground raceways and high-quality balls ensure low vibration levels and reduced acoustic noise in sensitive equipment.

•

Storage and handling

Store in original packaging in a clean, dry environment. Avoid exposure to corrosive chemicals. Handle with clean gloves to prevent contamination of raceways.

•

Mounting guidance

Apply force evenly to the ring being mounted. Use a press with appropriate support sleeves. Never apply impact force directly to the bearing.

•

Lubrication

Sealed variants are pre-lubricated for life. Open variants require grease or oil compatible with the operating speed and temperature range.
