1210J Bearing Product Overview & Core Advantages
The 1210J is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and compact design. Featuring an open construction and cylindrical bore, this precision bearing delivers reliable performance in demanding environments. Its double row design provides high rigidity and stable operation, making it suitable for machinery where space constraints and load-bearing requirements are critical. Manufactured from chrome steel and pre-lubricated for immediate use, it offers excellent durability within a standard temperature range.

| 1210 | Standard bore diameter code (50 mm) |
| J | Specifies CN radial internal clearance (Normal group) |
1210J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior radial stiffness and enables the bearing to support significant radial dynamic loads (5962 lbf).
- Optimized Internal Geometry: Carefully designed shoulder diameters (Inner: 61.7 mm, Outer: 78.1 mm) ensure proper load distribution and secure seating.
- Steel Cage & Material Integrity: The pressed steel cage and chrome steel components ensure dimensional stability and long service life under the specified limiting speed of 10,000 rpm.
- Standard Internal Clearance: The J suffix denotes CN clearance, offering a balance between operational smoothness and thermal expansion management.
1210J Bearing Typical Application Areas
This bearing is ideally suited for:
- Industrial gearboxes and transmission systems
- Electric motors and medium-duty pumps
- Material handling equipment and conveyor systems
- Agricultural machinery and general industrial machinery requiring robust bearing dimensions (50mm x 90mm x 20mm)
