6210-ZNRJEM (C3) Bearing Product Overview & Core Advantages
The 6210-ZNRJEM (C3) is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This metric bearing features a shielded design and a snap ring groove on its outer ring, facilitating secure axial location within a housing. Engineered with chrome steel rings, balls, and cage, it delivers reliable operation and excellent durability. A key characteristic is its C3 radial internal clearance, which makes it particularly suitable for applications with thermal expansion or where interference fits are used. Its high radial dynamic load rating and limiting speed ensure dependable performance under significant loads and rotational stresses.
6210-ZNRJEM (C3) Bearing Model Code Explained, Specifications & Naming Convention
The model number 6210-ZNRJEM (C3) provides detailed technical specifications through its suffixes:
- 6210: Basic model number indicating a single row deep groove ball bearing with a 50mm bore and 90mm outside diameter.
- Z: Denotes a shielded (non-contact) seal on one side, protecting the bearing interior from large contaminants.
- NR: Indicates a snap ring groove (fitted) on the outer ring. This feature allows for simplified axial positioning and secure housing retention.
- JEM: Specifies the cage design and material, in this case, a stamped steel cage.
- (C3): Specifies a greater than normal radial internal clearance. This is crucial for applications involving thermal expansion, high speeds, or heavy interference fits, preventing operational issues due to thermal expansion.
6210-ZNRJEM (C3) Bearing Structural Features & Performance Benefits
The design of the 6210-ZNRJEM (C3) translates into distinct performance advantages:
- Robust Construction & High Load Capacity: Manufactured entirely from chrome steel, including the cage, this bearing offers high strength and resistance to wear. Its radial dynamic load rating of 7891 lbf ensures reliable performance under significant radial loads.
- Secure Axial Location: The integrated snap ring groove on the outer ring simplifies assembly and provides a positive method for axial location, reducing the need for complex housing designs.
- Contamination Protection: The shielded (Z) design helps exclude large particulate contaminants, enhancing bearing service life in less-than-ideal environments.
- Operational Flexibility: The C3 internal clearance accommodates shaft and housing fits that cause clearance reduction, as well as differential thermal expansion between the inner and outer rings during operation.
- High-Speed Capability: With a limiting speed of 7,100 rpm, it is well-suited for a wide range of high-speed applications.
6210-ZNRJEM (C3) Bearing Typical Application Areas
The 6210-ZNRJEM (C3) is a versatile component found in numerous industrial sectors, including:
- Electric Motors and Generators
- Gearboxes and Power Transmission Systems
- Industrial Pumps and Compressors
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Any application requiring a reliable, high-capacity radial bearing with secure housing location and operational clearance for thermal effects.
