Product Overview: The 5311 Double Row Angular Contact Ball Bearing
The 5311 bearing is a high-performance component designed to handle complex load conditions. As part of our 5300 Series, this Double Row Angular Contact Ball Bearing features a 55mm bore diameter, a 120mm outer diameter, and a 49.2mm thickness. Its internal construction is similar to two single-row angular contact ball bearings arranged back-to-back, but in a more compact design. This configuration allows the 5311 to accommodate radial loads as well as axial loads in both directions, making it an excellent choice for applications requiring rigid shaft guidance and the ability to manage combined loads simultaneously.
Manufactured from high-quality bearing steel, the 5311 provides exceptional durability and reliability in demanding industrial environments. Its robust design ensures a stiff bearing arrangement, which is crucial for precision machinery.

Features of the 5311 Bearing
- Double Row Design: Two rows of balls provide a high load-carrying capacity for both radial and axial forces.
- Bi-directional Axial Load Support: Capable of accommodating axial loads in both directions, simplifying shaft arrangements.
- High Rigidity: Offers a stiff bearing assembly, ideal for applications where shaft deflection must be minimized.
- Compact and Space-Saving: Delivers the performance of a paired set of single-row bearings in a narrower, more integrated unit.
- Precision Engineering: Manufactured to precise tolerances for smooth, efficient, and reliable operation.
- Durable Construction: Made from high-purity, hardened bearing steel for long service life under heavy loads.
Applications of 5311 Bearings
- Industrial Pumps and Compressors: Provides rigid support for rotating shafts, handling the combined loads typical in fluid machinery.
- Gearboxes and Transmissions: Used to support gears and shafts, ensuring precise alignment and torque transfer.
- Machine Tool Spindles: Offers the high rigidity and rotational accuracy required for precision cutting and milling operations.
- Hoisting Equipment and Cranes: Suitable for pulleys, wheels, and lifting mechanisms that experience heavy radial and axial forces.
- Conveyor Systems: Supports rollers and drives that are subjected to continuous operation and combined loads.
- Agricultural Machinery: Employed in demanding applications like tillers, seeders, and harvesters where durability is key.
- Elevators and Escalators: Ensures smooth and reliable operation in drive systems and guide rollers.
Benefits of Using the 5311 Bearing
- Enhanced Load Capacity: The double row configuration handles significantly higher loads compared to a single-row bearing of similar size.
- Simplified Mounting: Replaces the need for matching and mounting two separate single-row bearings, reducing assembly time and complexity.
- Improved Operational Reliability: The inherent stiffness of the bearing minimizes shaft movement, leading to more stable and predictable machine performance.
- Versatile Performance: Its ability to manage combined loads makes it suitable for a wide variety of industrial and automotive applications.
- Cost-Effective Solution: Often provides a more economical and compact solution than using a matched pair of single-row angular contact bearings.
- Extended Service Life: Robust construction and high load capacity reduce wear and tear, leading to fewer replacements and less downtime.
