01. Enhanced Load Capacity in Standard Dimensions

Manufactured to ISO 03 series dimensions (25×62×17 mm), this bearing delivers substantial load capacity within a widely adopted size profile. With a dynamic load rating of 23.4 kN and static load rating of 11.6 kN, it is suitable for applications requiring robust radial support and moderate axial thrust capability .

02. Effective Dual Rubber Seal Design

Two synthetic rubber contact seals (2RS) provide reliable protection against moisture, dust, and contaminants while maintaining stable internal lubrication. This sealing solution is ideal for applications operating in humid, dirty, or wash-down environments where bearing longevity is critical .

03. Precision-Ground for Quiet & Smooth Operation

Available in precision grades up to ABEC 3 (P6), the 6305-2RS features optimized internal geometry and superfinished raceways to ensure minimal vibration, low noise, and consistent torque across various speed ranges and load conditions .

04. C3 Clearance Option Available

For applications involving higher operating temperatures or press-fit mounting, a C3 (greater than normal) radial internal clearance variant is available to accommodate thermal expansion and ensure optimal performance .

Design & Configuration

The 6305-2RS is supplied as standard with dual rubber contact seals, offering optimal protection in demanding environments. For applications where non-contact protection is sufficient and higher speed capability is required, the double metal shielded version (6305-ZZ) is available as an alternative configuration. Bearings with C3 internal clearance can also be supplied for high-temperature or high-interference fit applications .
