SFRW1zz Bearing Structural Features & Performance Benefits
Deep Groove Design: The optimized raceway geometry enables excellent radial load capacity while accommodating moderate axial loads in both directions, making it versatile for various loading conditions.
Stainless Steel Construction: All components including rings, balls, cage, and shields are manufactured from stainless steel, providing superior corrosion resistance and making it suitable for harsh environments and washdown applications.
Double Shielded Protection: The non-contact ZZ shields effectively prevent contamination ingress while maintaining low friction operation, extending bearing service life in contaminated environments.
Extended Inner Ring: The extended inner ring design simplifies installation and provides positive axial location, reducing the need for additional components and ensuring proper alignment.
Precision Performance: Manufactured to ABEC1 tolerance class with controlled radial internal clearance (MC3: 0.00008" to 0.0005"), ensuring smooth operation and consistent performance.
