SRW155 Bearing Product Overview & Core Advantages
The SRW155 is a precision single row deep groove ball bearing designed for high-performance applications requiring reliable radial load capacity. Manufactured entirely from stainless steel with an open design, this bearing offers excellent corrosion resistance and is suitable for a wide operating temperature range from -86 to 230 °F. Its extended inner ring facilitates easier mounting and secure positioning. As an ABEC1 class bearing, it provides dependable precision for general industrial use where consistent performance is critical.
SRW155 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW | Indicates a single row, deep groove ball bearing series. |
| 155 | Specifies the bearing size and dimensions in the inch series. |
| Open (Seal Type) | No integral seals or shields, allowing for higher limiting speeds and custom lubrication schemes. |
SRW155 Bearing Structural Features & Performance Benefits
- High-Grade Stainless Steel Construction: All components, including rings, balls, and cage, are made from stainless steel, providing superior corrosion resistance and durability in harsh environments.
- Optimized Radial Load Capacity: The deep groove raceway and 10 high-precision balls enable efficient handling of the specified radial dynamic and static loads.
- Extended Inner Ring: This design feature simplifies axial location and offers a larger contact surface for secure mounting.
- MC3 Internal Clearance: Provides a controlled radial internal clearance (0.00008" to 0.0005"), suitable for applications with moderate operational temperatures and fits.
- High-Speed Capability: The open design and stainless steel cage contribute to a high limiting speed of 47,700 rpm, making it suitable for demanding rotational applications.
SRW155 Bearing Typical Application Areas
This bearing is ideally suited for:
- Small precision instruments and medical devices
- High-speed spindles in dental handpieces and laboratory equipment
- Low-torque applications in food processing and packaging machinery
- Corrosive environment equipment requiring stainless steel bearings
- Various industrial machinery where reliable radial load support is needed
