61812-2RZ Bearing Product Overview & Core Advantages
The 61812-2RZ is a metric single row deep groove ball bearing designed for high-performance applications requiring compact design and reliable operation. This sealed bearing excels in handling significant radial loads while offering protection against contamination. Its precision P6 tolerance class ensures consistent performance and high running accuracy, making it suitable for demanding industrial environments where space is limited and reliability is paramount.
61812-2RZ Bearing Model Code Explained, Specifications & Naming Convention
- 61812: Basic series designation for a metric single row deep groove ball bearing with a 60mm bore and 78mm outside diameter.
- 2RZ: Indicates the bearing is fitted with non-contact seals on both sides. The "RZ" seal type provides effective protection against dust and moisture while maintaining low friction and enabling high rotational speeds.
61812-2RZ Bearing Structural Features & Performance Benefits
Optimized Sealing & Lubrication: The 2RZ seals effectively shield the internal components from contaminants, while the factory-applied grease lubrication provides long-term, maintenance-free operation within the specified temperature range of -30°C to 120°C.
High-Speed Capability: The combination of a stainless steel cage, precision-ground chrome steel components, and low-friction seals enables a high limiting speed of 8,500 rpm.
Robust Load Capacity: With a dynamic load rating of 2675 lbf and a static load rating of 2563 lbf, this bearing is engineered to handle substantial radial loads in compact spaces.
Precision Engineering: Manufactured to P6 tolerance class with standard CN radial internal clearance, this bearing ensures smooth operation, reduced vibration, and enhanced system accuracy.
61812-2RZ Bearing Typical Application Areas
The 61812-2RZ is ideally suited for applications requiring a compact, sealed, and high-precision bearing solution, including:
- Electric Motors and small AC/DC Motors
- Precision Gearboxes and transmission systems
- Office automation equipment such as Printers and Copiers
