SMR95zz Bearing Product Overview & Core Advantages
The SMR95zz is a miniature single row deep groove ball bearing engineered for precision applications requiring compact design and reliable performance. Constructed entirely from stainless steel, it offers excellent corrosion resistance. Its key advantages include the ability to handle significant radial loads and moderate axial loads in both directions, making it a versatile and space-saving solution. The inclusion of shielded seals (ZZ) helps retain lubrication and exclude contaminants, contributing to a long service life and consistent operation in demanding environments.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| SMR95 | Standard designation for a miniature bearing series with a 5mm bore and 9mm outside diameter. |
| zz | Indicates the bearing is equipped with shielded seals on both sides. These non-contact shields protect against large particulate contamination and help retain grease. |
SMR95zz Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and complement of eight precision balls enable smooth operation and high radial load capacity for its compact bearing dimensions (5x9x3 mm).
- Corrosion Resistance: Manufactured from 300 series stainless steel for the rings, balls, cage, and shields, this bearing is suitable for applications exposed to moisture and corrosive agents.
- Precision & Speed: Built to ABEC1 tolerance class with an MC3 radial internal clearance (0.002mm to 0.013mm), ensuring consistent performance. The optimized design supports a limiting speed of 45,000 rpm.
- Shielded Protection: The ZZ shields provide effective contamination protection without significantly increasing rotational torque, making them ideal for high-speed applications where sealing is required.
SMR95zz Bearing Typical Application Areas
This bearing is ideally suited for compact, high-speed devices across various industries, including:
- Small Precision Motors (e.g., drone motors, miniature DC motors)
- Medical and Dental Handpieces
- Office Automation Equipment (e.g., printers, scanners)
- Instrumentation and Control Systems
- Radio-Controlled Models and Hobbyist Projects
