SRW1zz Bearing Product Overview & Core Advantages
The SRW1zz is a single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. Manufactured entirely from stainless steel, it offers excellent corrosion resistance. Its compact inch series design features an extended inner ring for secure mounting and a shielded configuration to protect against contamination. This bearing is engineered to primarily handle radial loads and is suitable for a wide operating temperature range, making it an ideal choice for compact assemblies demanding long service life and consistent performance.
SRW1zz Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| SRW1 | Indicates the specific bearing series and size in the manufacturer's inch-based nomenclature. |
| zz | Signifies that the bearing is equipped with shields on both sides (2Z). This provides effective protection against solid contaminants while allowing for higher rotational speeds compared to contact seals. |
SRW1zz Bearing Structural Features & Performance Benefits
- Robust Construction & Corrosion Resistance: The use of stainless steel for all critical components (rings, balls, cage, and shield) ensures superior resistance to rust and corrosion, which is critical for operation in harsh environments and for applications requiring washdown.
- High-Speed Capability: The combination of a stainless steel cage, low-friction deep groove raceway, and non-contact shields enables a high limiting speed of 81,000 rpm, making it suitable for demanding high-speed applications.
- Precision & Reliability: Manufactured to ABEC1 tolerance class, this bearing provides reliable and consistent running accuracy. The specified MC3 radial internal clearance ensures optimal performance under normal operating conditions.
- Extended Inner Ring: The extended inner ring design facilitates easier and more secure axial location and locking of the bearing within an assembly.
SRW1zz Bearing Typical Application Areas
- Precision Instruments and optical devices
- Small electric motors and spindles
- Medical and dental handpieces
- Food processing and packaging machinery
- Office automation equipment (e.g., printers, scanners)
- Radio control models and drones
