1318-M-C3 Bearing Product Overview & Core Advantages
The 1318-M-C3 is a double row angular contact ball bearing designed for applications requiring high load capacity and operational stability. This precision bearing is engineered to accommodate significant combined loads—simultaneously handling radial forces and axial loads in both directions. Its compact design, featuring a 90 mm bore and 190 mm outside diameter, offers a robust solution for machinery demanding high rigidity and reliable performance. The C3 radial internal clearance makes it particularly suitable for applications with thermal expansion or where interference fits are used, ensuring consistent operation under varying conditions.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1318 | Standard bearing series designation indicating specific bearing dimensions (90mm bore × 190mm OD × 43mm width) |
| M | Brass cage construction for enhanced durability and performance at moderate speeds |
| C3 | Radial internal clearance greater than normal, suitable for applications with thermal expansion or interference fits |
1318-M-C3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides superior stiffness compared to single row bearings, enabling stable operation under heavy combined loads. With a dynamic load rating of 26,325 lbf and static load rating of 9,900 lbf, this bearing delivers exceptional load-bearing performance.
Optimized Construction: Manufactured from chrome steel for both rings and balls, the bearing ensures high durability and wear resistance. The brass cage maintains proper ball spacing and alignment, contributing to smooth operation and extended service life.
Operational Versatility: The C3 clearance accommodates thermal expansion in applications where operating temperatures vary, preventing premature failure. The open seal type allows for custom lubrication solutions tailored to specific application requirements.
Speed Capability: With a limiting speed of 4,500 rpm, this bearing is suitable for various industrial applications requiring moderate to high rotational speeds.
