The FAFNIR RSA 1 3/16 is a premium wide inner ring insert ball bearing designed for severe-duty industrial and agricultural applications. Featuring a robust, heat-treated 52100 high-carbon steel construction, this bearing ensures exceptional load capacity and long service life. The wide inner ring provides superior shaft stability and support, significantly reducing misalignment stresses compared to narrow-ring counterparts. Its precision-ground raceways and high-quality ball complement minimize rotational friction, enhancing energy efficiency. Equipped with highly effective R-Seals and flingers, the RSA 1 3/16 provides excellent protection against harsh contaminants, dust, and moisture ingress, ensuring the pre-applied lubrication remains effective over extended operational periods.
Optimized for use in standard industrial housings (such as pillow blocks, flange units, and take-up assemblies), the RSA 1 3/16 utilizes an eccentric locking collar mechanism for quick, secure, and positive shaft attachment. This ease of installation reduces labor time and guarantees a tight fit, minimizing vibration and potential damage from rotational slip. This bearing is the ideal choice for heavy-duty power transmission, conveyor systems, fans, and mixers where reliability and reduced maintenance are critical. Standardized dimensions allow for direct interchangeability with many industry-standard insert bearings (including the common G1100KRRB cross-reference).
