MR106 Bearing Product Overview & Core Advantages
The MR106 is a metric single row deep groove ball bearing engineered for compact, high-precision applications requiring reliable radial load support. Constructed from chrome steel with a stainless steel cage, it offers excellent durability and consistent performance. Its open design allows for versatile lubrication options, making it suitable for a wide operational temperature range from -30°C to 110°C. This bearing is ideal for applications where space is limited but performance cannot be compromised.
MR106 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| MR106 | Standard model designation for a metric single row deep groove ball bearing. |
| Open (Seal Type) | No integral seals or shields. Requires external sealing and lubrication for the application environment. |
| ABEC1 | Specifies the tolerance class, indicating standard precision suitable for a wide range of general applications. |
| MC3 | Denotes the radial internal clearance group (C3), which is greater than normal, making it suitable for applications with thermal expansion or where interference fits are used. |
MR106 Bearing Structural Features & Performance Benefits
Optimized Single Row Design: The deep groove raceway and complement of 10 precision balls enable efficient handling of radial loads and moderate axial loads in both directions.
High-Speed Capability: The lightweight stainless steel cage effectively guides the balls, contributing to a high limiting speed of 45,000 rpm, which is essential for demanding small motor and spindle applications.
Precision & Reliability: Manufactured to ABEC1 tolerances, this bearing ensures consistent running accuracy. The specified MC3 radial clearance (0.002mm to 0.013mm) provides operational stability in environments prone to thermal changes.
Robust Material Construction: Rings and balls made from chrome steel provide high load capacity and wear resistance, while the stainless steel cage offers excellent corrosion resistance.
MR106 Bearing Typical Application Areas
- Small Electric Motors: Ideal for use in compact fans, drones, and power tools due to its small bearing dimensions (6x10x2.5 mm) and high-speed performance.
- Precision Instruments: Suitable for optical encoders, medical devices, and gauges where low noise and smooth operation are critical.
- Office Automation Equipment: Commonly used in printers, scanners, and small drives.
- Radio-Controlled Models: A standard choice for high-performance servos and miniature gearboxes.
