SMR105zz Bearing Product Overview & Core Advantages
The SMR105zz is a miniature deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. As a single row, shielded metric bearing, it excels in handling radial loads efficiently. Constructed entirely from stainless steel, it offers excellent corrosion resistance, making it suitable for demanding environments. Its compact design (5mm bore, 10mm OD) and ABEC1 precision class make it an ideal choice for applications prioritizing space savings, durability, and consistent operation.
SMR105zz Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Advantage |
|---|---|---|
| zz | Double-sided steel shields (2Z) | Provides effective protection against contamination from solid particles, enhancing bearing life and reliability in dirty environments. |
| (Implied) | Requires Lubrication | Allows for the selection of specialized lubricants to optimize performance for specific speed and temperature range requirements. |
SMR105zz Bearing Structural Features & Performance Benefits
- Robust Stainless Steel Construction: All components, including rings, balls, cage, and shields, are made from stainless steel. This provides superior corrosion resistance, essential for applications exposed to moisture or chemicals, and ensures long-term dimensional stability.
- Optimized Load Capacity: The deep groove raceway and complement of 8 precision balls enable efficient handling of radial dynamic loads up to 74 lbf, making it a reliable component in various mechanical assemblies.
- Shielded for Protection: The double-sided non-contact steel shields (zz) retain lubricant and effectively exclude contaminants, significantly reducing the risk of premature failure and extending service intervals.
- Precision and Speed: Manufactured to ABEC1 tolerance class with a controlled MC3 radial internal clearance (0.002mm to 0.013mm), this bearing ensures smooth, low-vibration operation and is capable of operating at limiting speeds up to 45,000 rpm.
SMR105zz Bearing Typical Application Areas
- Small Precision Motors (e.g., stepper motors, DC micromotors)
- Office Automation Equipment (e.g., printers, scanners, copiers)
- Medical and Dental Devices (e.g., handheld tools, pumps)
- Instrumentation and Control Systems
- Radio-Controlled Models and Drones
- Food Processing Equipment (benefiting from stainless steel construction)
