SRW155zz Bearing Product Overview & Core Advantages
The SRW155zz is a single row deep groove ball bearing designed for precision applications requiring reliable performance in compact spaces. Manufactured entirely from stainless steel, this bearing offers excellent corrosion resistance. Its shielded (ZZ) design provides effective protection against contaminant ingress while maintaining low friction. With an ABEC1 tolerance class and a standardized MC3 radial internal clearance, it delivers consistent operation and is suitable for applications demanding high rotational accuracy. The extended inner ring facilitates easier mounting and handling.

SRW155zz Bearing Structural Features & Performance Benefits
Compact & Robust Design: The single row deep groove construction provides a compact cross-section while maintaining high radial load capacity (62 lbf dynamic / 24 lbf static). The deep raceways enable smooth operation under various load conditions.
Enhanced Protection: The double-shielded (ZZ) configuration effectively seals the bearing interior from dust and other particulates, extending service life in contaminated environments. The shields are manufactured from 300 Series Stainless Steel for corrosion resistance.
Precision Performance: Built to ABEC1 tolerance standards with MC3 radial clearance, this bearing ensures consistent running accuracy and low vibration. The stainless steel cage and components provide dimensional stability across the operating temperature range (-86 to 230 °F).
High-Speed Capability: With a limiting speed of 47,700 rpm, the bearing is suitable for high-speed applications. The optimized design with 10 precision balls ensures balanced operation at elevated rotational speeds.
