Product Description
GCr15 6304-2RS Bearing 20x52x15 Rubber Seal Bearings For Motors / Appliances
Product Overview
The 6304-2RS is a deep groove ball bearing with double-sided rubber seals designed for motors and appliances. This bearing excels in environments requiring protection against contaminants like dust, dirt, and moisture.
Design & Construction
Inner & Outer Rings: Precision-machined with 20mm inner diameter and 52mm outer diameter. Deep, accurately crafted raceways ensure smooth movement and even load distribution.
Rolling Elements: High-precision steel balls made from top-grade bearing steel with ultra-smooth surface finish for reduced friction.
Cage: Sheet metal construction maintains proper ball spacing and guides rotation.
Sealing: Double-sided rubber seals (2RS) provide reliable protection against dust, dirt, and moisture.

- Quiet Operation: Optimized for low-vibration, quiet performance ideal for sensitive applications
Material Quality
Rings & Balls: High-carbon chromium bearing steel with vacuum degassing for high density and excellent mechanical properties
Cage: Sheet metal construction offering strength, cost-effectiveness, and good thermal conductivity
Applications
- Industrial Machinery: Conveyors, pumps, small machine tools
- Electric Motors: Medium-power industrial fans and machine tools
- Automotive Industry: Water pumps, alternators
- Household Appliances: Washing machines, dryers, large fans
Installation & Maintenance
Installation: Use appropriate tools (bearing press or installation sleeve) for even installation. Ensure proper alignment and use locking nut for tapered shafts.
Maintenance: Use lithium-based grease (fill 1/3 to 1/2 of internal space) or ISO VG 32/46 oil for high-speed applications. Monitor temperature (60-80°C max) and check for abnormal vibration or noise.
Summary: The 6304-2RS bearing is a reliable, versatile component offering excellent performance with contamination resistance, good load-handling capacity, and quiet operation for various mechanical systems.
