SRW2-6zz Bearing Product Overview & Core Advantages
The SRW2-6zz is a single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. This shielded bearing is pre-lubricated for immediate use and is engineered to handle primarily radial loads efficiently. Its compact design, featuring an extended inner ring, makes it ideal for applications where space is limited and high reliability is paramount.

| zz | Indicates non-contact shields on both sides for contaminant protection while maintaining low torque. |
SRW2-6zz Bearing Structural Features & Performance Benefits
- Compact & Robust Design: The single row deep groove raceway and stainless steel construction provide a robust yet lightweight solution with a high radial dynamic load rating of 110 lbf.
- Extended Inner Ring: The extended inner ring facilitates easier mounting and axial location in assemblies.
- Shielded Protection: The 300 Series Stainless Steel shields (zz) protect the bearing internals from contaminants like dust and debris without significantly increasing friction, contributing to a limiting speed of 47,700 rpm.
- Precision & Stability: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), ensuring consistent and smooth operation.
SRW2-6zz Bearing Typical Application Areas
This bearing is commonly used in:
- Precision Instruments and small medical devices
- Small Motors and miniature gearboxes
- Office automation equipment (e.g., printers, scanners)
- Radio-controlled models and drones
- Low-torque, high-speed spindles
