SRW166 Bearing Product Overview & Core Advantages
The SRW166 is a single row deep groove ball bearing designed for precision radial load applications. Manufactured entirely from stainless steel, this bearing offers excellent corrosion resistance and reliable performance. Its compact design and extended inner ring facilitate easier mounting and secure positioning. As an open-type bearing, it provides flexibility for custom lubrication solutions to meet specific operational requirements, making it a versatile component for demanding environments.
SRW166 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW | Indicates a single row, deep groove ball bearing series with an extended inner ring. |
| 166 | Specifies the bearing dimensions (Bore: 0.1875", OD: 0.375", Width: 0.125"). |
| Open (Seal Type) | No seals or shields, allowing for high-speed operation and custom re-lubrication. |
SRW166 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row deep groove raceway and robust stainless steel construction provide stable support for radial loads, with a dynamic load rating of 122 lbf.
- Precision Performance: Manufactured to ABEC1 tolerance class with a controlled radial internal clearance (MC3), ensuring smooth and consistent operation.
- Corrosion Resistance: All components, including rings, balls, and cage, are made from stainless steel, making it suitable for harsh or washdown environments.
- Extended Inner Ring: The inner ring protrudes beyond the outer ring, simplifying axial location and mounting in assemblies.
SRW166 Bearing Typical Application Areas
- Precision Instruments and Optical Devices
- Small Electric Motors and Miniature Gearboxes
- Medical and Dental Equipment
- Food Processing Machinery (where corrosion resistance is critical)
- Robotics and Automation Components
