1315-M-C3 Bearing Product Overview & Core Advantages
The 1315-M-C3 is a double row angular contact ball bearing designed for applications requiring high rigidity and reliable performance under combined loads. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant radial loads and moderate axial loads in both directions simultaneously. Its compact construction and C3 radial internal clearance make it suitable for arrangements where thermal expansion must be accommodated, ensuring stable operation in demanding industrial environments.
1315-M-C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1315 | Standard bearing series designation indicating specific bearing dimensions: 75mm bore, 160mm OD, 37mm width |
| M | Brass cage construction, providing excellent strength and durability for high-speed applications |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or where interference fits are used |
1315-M-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness compared to single row bearings, effectively handling combined loads including radial forces and bidirectional axial loads. With a dynamic load rating of 17,842 lbf and static load rating of 6,750 lbf, this bearing delivers reliable performance in heavy-duty applications.
Optimized High-Speed Performance: The brass cage (M designation) ensures stable operation at limiting speeds up to 5,600 rpm, making it suitable for high-speed bearing applications. The precision-ground chrome steel components contribute to smooth rotation and reduced vibration.
Thermal Compensation & Long Service Life: The C3 clearance accommodates thermal expansion in applications where operating temperatures vary, preventing premature failure. Pre-lubricated construction with chrome steel rings and balls ensures extended service life with minimal maintenance requirements.
