MR95 Bearing Product Overview & Core Advantages
The MR95 is a metric single row deep groove ball bearing designed for precision applications requiring compact dimensions and reliable performance. Engineered with chrome steel rings and balls combined with a stainless steel cage, this bearing delivers excellent durability and corrosion resistance. Its fundamental design excels at carrying radial loads and is manufactured to ABEC1 precision class, making it an ideal component for applications demanding high reliability in confined spaces.
MR95 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MR95 | Standard model designation for a metric series, single row deep groove ball bearing. |
| Open (Seal Type) | No integral seals or shields. This allows for higher limiting speeds and requires external lubrication and protection from contaminants. |
| MC3 (Internal Clearance) | Specifies a greater than normal radial internal clearance (0.002mm to 0.013mm), suitable for applications with significant thermal expansion or where interference fits are used. |
MR95 Bearing Structural Features & Performance Benefits
- Optimized Load Capacity: The deep groove raceway and complement of eight 1.2mm balls provide a robust radial dynamic load rating of 82 lbf and a static rating of 30 lbf, ensuring reliable operation under load.
- High-Speed Capability: The lightweight stainless steel cage and open design contribute to a high limiting speed of 50,000 rpm, making it suitable for demanding high-speed applications.
- Precision & Stability: Manufactured to ABEC1 tolerance class with tight dimensional control on the 5mm bore and 9mm outside diameter, this bearing ensures smooth and precise rotation with minimal runout.
- Material Integrity: Constructed from chrome steel for rings and balls, offering high hardness and wear resistance, paired with a corrosion-resistant stainless steel cage for enhanced longevity.
MR95 Bearing Typical Application Areas
- Small Precision Motors and Spindles
- Medical Devices and Dental Handpieces
- Office Automation Equipment (e.g., small printers, scanners)
- Instrumentation and Precision Guiding Mechanisms
- RC Models and Miniature Drone Motors
