SRW166zz Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway design enables efficient radial load distribution across all eight precision balls, ensuring smooth rotation and reduced vibration.
Full Stainless Steel Construction: All components including rings, balls, cage, and shields are manufactured from stainless steel, providing excellent corrosion resistance and making the bearing suitable for harsh environments and washdown applications.
Double Shield Protection: The 300 series stainless steel shields on both sides effectively retain lubrication while excluding contaminants, significantly extending the bearing's operational life in dusty or humid conditions.
Extended Inner Ring: The 0.1562" inner ring width provides additional mounting surface and improved axial location capability, enhancing overall system stability.
Precision Engineering: With ABEC1 tolerance class and MC3 radial internal clearance (0.00008" to 0.0005"), this bearing delivers consistent performance and reliable operation in precision applications.
