6307 2RS DPI 35x80x21 Deep Groove Ball Bearing

Main description

The 6307 2RS DPI deep groove ball bearing with dimensions 35x80x21 mm is a robust single row bearing designed for applications requiring increased load capacity, reliable sealing and long service life in demanding industrial environments.

A deep groove ball bearing from the 63xx series is engineered to handle higher loads compared to the lighter 62xx series, thanks to its reinforced internal design and larger rolling elements. The 6307 size is widely used in industrial machinery, electric motors and transmission systems where both radial and moderate axial loads are present.

The 2RS version is equipped with rubber seals on both sides, providing effective protection against dust, moisture and contaminants while retaining lubrication inside the bearing. This ensures maintenance free operation in many applications and significantly extends service intervals.

Construction and design

The DPI 6307 2RS is a single row deep groove ball bearing with optimized raceway geometry for smooth rotation and efficient load distribution.

The double sided rubber seals protect internal components from contamination and prevent grease leakage. This design improves durability and allows the bearing to operate in more challenging environments without additional maintenance.

Its robust construction provides stable performance under higher loads while maintaining low noise and vibration levels.
