R6-2RS Fortified Deep Groove Ball Bearing for Fractional Motors & Power Transmission | 3/8" × 7/8" × 9/32"

R6-2RS Fortified Deep Groove Ball Bearing for Fractional Motors & Power Transmission | 3/8" × 7/8" × 9/32"

Engineered to deliver unwavering stability in environments exposed to dust, dirt, and moisture, the R6-2RS is a premium inch-dimensioned radial ball bearing. Fortified with two synthetic rubber contact seals (2RS), this component effectively blocks external contaminants from entering the raceways while retaining critical lubricating grease. Because the flexible seal lips maintain light, constant contact with the inner ring, the R6-2RS offers vastly superior ingress protection compared to metal-shielded designs. This makes it an essential choice for 3/8-inch shaft assemblies found in fractional horsepower motors, lawn equipment, and automated conveyor systems.

R6-2RS Deep Groove Ball Bearing 9.525 x 22.225 x 7.142 mm | Dual NBR Protection

Built to rigorous ISO precision standards, this bearing leverages a highly adaptable inch-series profile to manage continuous radial loads alongside moderate axial forces. The integrated NBR (Nitrile Butadiene Rubber) seals act as a durable barrier, preventing lubricant wash-out and protecting the finely polished steel balls from abrasive wear. By locking out grit and locking in lubrication, the R6-2RS guarantees smooth, low-friction rotation with absolutely zero maintenance, drastically extending equipment uptime in demanding indoor and outdoor conditions.

Key Performance Features

01. Advanced NBR Contact Sealing

Fitted with double steel-reinforced Nitrile Rubber seals, this bearing provides a watertight and dustproof internal environment. This contact-sealing architecture is essential for applications where the bearing is exposed to the elements, preventing premature failure caused by grit scoring the internal balls and raceways.

02. Standardized 3/8" Shaft Compatibility

Featuring a precision-ground 3/8-inch bore, the R6 series is globally recognized for its versatility in compact mechanical designs. The optimized raceway curvature minimizes rolling resistance, allowing the bearing to efficiently support both radial and thrust loads without compromising structural integrity.

03. High-Durability GCr15 Chrome Steel

Manufactured from ultra-clean, vacuum-degassed 52100/GCr15 bearing steel. Through advanced heat treatment processes, the inner and outer rings achieve superior Rockwell hardness, ensuring high fatigue resistance, low operational noise, and a significantly extended service life under heavy vibration.
