SW R8-2RS Deep Groove Ball Bearing | 1/2" x 1-1/8" Sealed - High Reliability Imperial Standard
The SW R8-2RS is a precision-engineered Deep Groove Ball Bearing designed for critical applications requiring robust sealing and reliable performance in moderate to high-speed environments. Featuring the widely adopted 1/2 inch bore (12.7mm) and 1 1/8 inch outer diameter (28.575mm), this imperial-sized bearing adheres to stringent industry standards. Its construction utilizes high-quality 52100 bearing steel, ensuring exceptional hardness, fatigue life, and load-carrying capability. The critical 2RS configuration denotes two reinforced rubber seals contacting the inner ring, effectively locking in premium grease while providing superior defense against dust, moisture, and contaminants, significantly extending maintenance intervals and operating longevity.
Optimized for seamless integration into light industrial motors, precision instruments, material handling equipment, and consumer appliances, the SW R8-2RS delivers the essential balance of durability and low frictional torque. As a reliable component within the SW industrial portfolio, this bearing minimizes unexpected downtime and operational noise. Our commitment to tight tolerance control and optimized internal geometry ensures consistent performance across its defined operating envelope, making the R8-2RS a cost-effective choice for OEM replacement or new equipment design where reliable, sealed imperial bearings are mandatory.
