Detailed Product Information
Design & Protection
The 6204 RS features the universal deep groove raceway, suitable for carrying high radial and moderate axial loads. Its key feature is the synthetic rubber (NBR) contact seal on one side. This design provides enhanced protection against fine particulates on the sealed side, making it ideal for applications where one bearing face is exposed to a harsher environment, such as in certain motor end covers or exposed gearboxes. The opposite, open side allows for design flexibility.
Performance Characteristics
This bearing is built for durable and reliable performance. The contact seal effectively excludes contaminants, contributing to extended service intervals. We produce the 6204 RS to standard industrial tolerances, with the capability to provide P5 precision grades, ensuring superior rotational accuracy and smoothness for precision mechanisms that also require environmental protection on one side.
Applications
The 6204 RS is commonly specified for a wide array of industrial applications where one-sided sealing offers the optimal solution, including:
- Electric Motors: Frequently used in industrial motors, fan motors, and pumps where one side requires protection from the internal or external environment.
- Gearboxes and Transmissions: Suitable for units where sealing is needed on the input or output side against dust or splash.
- Agricultural Machinery: Components in drives and rollers where one-sided contaminant exposure is typical.
- General Industrial Machinery: A reliable choice for various machinery requiring a balance of sealing, load capacity, and speed.
