1318-M Bearing Product Overview & Core Advantages
The 1318-M is a double row angular contact ball bearing designed for applications requiring high rigidity and precision performance. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant combined loads—both radial and bidirectional axial forces—simultaneously. Its compact double-row construction provides exceptional stability, making it ideal for high-reliability machinery where space constraints and operational accuracy are critical. The bearing's optimized bearing dimensions (90 mm bore, 190 mm OD, 43 mm width) offer a robust solution for demanding industrial environments.

| (Open) | No seal/shield, allowing for custom lubrication solutions and optimal heat dissipation |
1318-M Bearing Structural Features & Performance Benefits
- High Rigidity: The double row design creates a wide supporting surface, significantly increasing system stiffness and reducing deflection under heavy combined loads.
- Superior Load Capacity: Engineered to withstand substantial radial loads and bidirectional axial loads simultaneously, making it versatile for complex loading conditions.
- Optimized High-Speed Performance: The brass cage (M suffix) ensures dimensional stability at high rotational speeds, while the open structure facilitates efficient lubrication management.
- Pre-Lubricated for Immediate Service: Factory-applied lubrication enables immediate installation and initial operation, reducing setup time and ensuring proper initial running-in.
- Precision Ground Components: Manufactured with tight dimensional tolerances and CN radial internal clearance for consistent performance in precision applications.
1318-M Bearing Typical Application Areas
- Industrial Gearboxes and power transmission systems
- Machine Tool Spindles requiring high rigidity and precision
