1216 C/3 Bearing Product Overview & Core Advantages
The 1216 C/3 is a double row angular contact ball bearing engineered for applications requiring high rigidity and reliable performance under combined loads. This metric bearing features an open design without integral seals, allowing for optimal lubrication management in controlled environments. Its compact bearing dimensions (80mm bore, 140mm OD, 26mm width) and robust construction make it an ideal choice for high-precision machinery where space constraints and load capacity are critical factors. The bearing is pre-lubricated and ready for installation, offering excellent operational readiness.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1216 | Standard bearing designation indicating size series and bore diameter (80mm) |
| C | Specifies a 15° contact angle, optimized for handling combined radial and axial loads |
| 3 | Indicates CN radial internal clearance (normal clearance group), suitable for most industrial applications |
1216 C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness compared to single row bearings, effectively handling combined radial and axial loads from multiple directions. With a dynamic load rating of 8932 lbf and static load rating of 3825 lbf, this bearing delivers reliable performance in demanding applications.
Precision Engineering: Manufactured from chrome steel for both rings and balls, the bearing ensures dimensional stability and long service life. The nylon cage contributes to smooth operation at the limiting speed of 6000 rpm, while reducing friction and heat generation.
Optimized Internal Clearance: The CN radial internal clearance provides optimal performance under normal operating conditions and temperatures ranging from -30°C to 110°C.
