SFRW2-6zz Bearing Product Overview & Core Advantages
The SFRW2-6zz is a precision miniature ball bearing designed for applications requiring compact size and reliable performance. As a single row radial ball bearing with shielded construction, it excels in handling radial loads efficiently. Manufactured entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. Its compact dimensions (0.125" bore, 0.375" OD) and ABEC1 precision class make it an ideal choice for high-speed, small-scale mechanical systems where space is at a premium and consistent operation is critical.

SFRW2-6zz Bearing Structural Features & Performance Benefits
Flanged Design: The integral flange on the outer ring (0.422" diameter) provides secure axial location and simplifies housing design, reducing assembly time and cost.
Extended Inner Ring: The extended inner ring (0.1719" width) offers a larger contact surface for secure shaft mounting and facilitates better sealing arrangements.
Stainless Steel Construction: All components, including rings, balls, cage, and shields, are manufactured from stainless steel, providing superior corrosion resistance and enabling operation in a wide temperature range (-86 to 230 °F).
High-Speed Capability: With a limiting speed of 47,700 rpm and optimized 7-ball design, this bearing delivers smooth operation at high rotational velocities.
Precision Performance: The ABEC1 tolerance class and controlled radial internal clearance (MC3) ensure consistent running accuracy and low vibration.
