OWC One Way Clutch Needle Roller Bearings

The OWC (One Way Clutch) Bearings are mechanical components designed to allow rotational movement in one direction while preventing motion in the opposite direction. These bearings are commonly used in applications requiring torque transmission, indexing, backstopping, or overrunning functions. Key features and examples include:

1. Design and Functionality:

• OWC bearings often integrate internal ball bearings and roller bearings (e.g., the GMN RA series) to handle high torque and ensure smooth unidirectional operation. They may also include lifetime oil lubrication and sealing systems for durability in demanding environments.
• Some variants, like the OWC612GXRZ model, have specific dimensions (e.g., 6×12×5 mm) and are designed for compact applications, such as in machinery or automotive systems.

1. Material and Construction:

• Components like raceways and rings are typically made of hardened bearing steel for wear resistance, while seals may use rubber (e.g., GMN rubber seals) to prevent contamination.
• Simpler designs, such as those without internal bearings, might use steel balls for rolling mechanisms and POM (polyoxymethylene) bodies to avoid marking delicate materials during handling.

1. Applications:

• Widely used in CNC machines, robotics, spindles, and motors, OWC bearings support precise motion control and load management.
• Specific models, like GMN’s RA series, are suited for indexing clutches or backstops, offering dual-sealed units with keyway connections for secure mounting.
