MR126The MR126 Open Type Bearing is a versatile deep groove ball bearing suitable for various industrial sectors. Key industries include general machinery equipment, small to medium-sized electric motors, household appliances (e.g., fans, washing machines), automotive auxiliary components (e.g., water pumps, generators), office equipment, power tools, and light industrial machinery. Its open design makes it ideal for clean, low to medium-speed applications where pre-lubrication is not required, serving as a fundamental component in mechanical transmission systems across industries.
Product structure:
The MR126 is a standard open-type deep groove ball bearing with a simple and reliable structure. Its key dimensional parameters are: 6mm bore, 12mm outer diameter, and 3mm width. The internal structure consists of a deep-groove stamped steel raceway, a set of high-carbon chromium steel balls, and a cage. The open design means there are no seals or shields on either side, allowing for direct visual inspection and facilitating the application of grease according to specific operating conditions before use.
Key performance features:
The main performance features of this bearing include: 1. High Versatility: Suitable for radial loads and moderate bidirectional axial loads. 2. High-Speed Capability: The open design reduces friction, allowing for higher rotational speeds with proper lubrication. 3. Flexible Installation & Maintenance: No seals facilitate easy installation, cleaning, and relubrication. 4. Cost-Effective: Simple construction offers low manufacturing cost and high value. 5. Good Interchangeability: Complies with ISO dimensional standards, allowing direct replacement with similar domestic and international bearings. 6. Fundamental Reliability: Provides stable operation and long service life in clean environments.
Technical Specifications and Requirements:
Technical specifications and requirements for this bearing are as follows: 1. Dimensional Standards: Strictly complies with ISO 15:2011 (GB/T 276) for boundary dimensions of deep groove ball bearings. 2. Precision Class: Typically supplied with Normal tolerance class (P0 grade), ensuring smooth operation for general applications. 3. Clearance: Supplied with standard radial internal clearance (C0 group), meeting most common operating conditions. 4. Materials: Rings and balls are typically made of high-carbon chromium bearing steel (e.g., GCr15), with cages usually being stamped steel. 5. Lubrication Requirements: Usually supplied with anti-rust oil. Users must apply suitable grease (e.g., lithium-based) based on actual speed, load, and operating temperature (recommended -30°C to +120°C). 6. Operating Environment: Suitable for clean environments without significant dust or moisture ingress. External seals are required if conditions are harsh. 7. Load & Speed: Refer to the manufacturer's catalog for specific dynamic/static load ratings and speed limits. Overloading and exceeding speed limits must be avoided in operation.
