1216J Bearing Product Overview & Core Advantages
The 1216J double row angular contact ball bearing is engineered for applications requiring high rigidity and precise operation under combined loads. This metric bearing features an open design without seals, allowing for optimal lubrication access and making it suitable for systems where controlled lubrication is applied. Its double row construction enables it to accommodate significant radial loads while also handling moderate axial loads in both directions. With a bore diameter of 80 mm and compact cross-section, it delivers robust performance in space-constrained, high-precision environments demanding reliability and dimensional stability.
1216J Bearing Model Code Explained, Specifications & Naming Convention
- 12: Indicates the series, defining the dimensional boundary and cross-sectional size.
- 16: Represents the bore diameter code; for metric bearings, this corresponds to 80 mm (calculated as 16 × 5 = 80 mm).
- J: Signifies an optimized internal geometry and CN radial internal clearance as standard, suitable for most industrial applications under normal operating conditions.
1216J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact ball bearing design provides enhanced stiffness and supports substantial radial dynamic load ratings (8932 lbf) and static loads (3825 lbf), effectively managing combined radial and axial loads.
- Optimized for Precision: Manufactured from chrome steel for rings, balls, and a steel cage, the bearing ensures consistent performance, durability, and resistance to deformation under load.
- Speed & Thermal Performance: With a limiting speed of 6000 rpm and a temperature range of -30°C to 110°C, it is suited for a variety of industrial speeds and environments. The open structure facilitates efficient lubrication management for heat dissipation.
- Precision Tolerances: Strict dimensional tolerances on bore, outside diameter, and width ensure reliable fit and alignment, contributing to smooth operation and extended service life.
1216J Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles and precision rotating assemblies
- Material Handling Equipment such as conveyor pulleys
- Pumps and Compressors where radial load capacity is critical
- Agricultural and Construction Machinery drivetrains
