Simple and Versatile: The basic structure consists of an inner ring, an outer ring, a set of steel balls, and a cage. It is the most commonly used type of rolling bearing, suitable for a variety of mechanical applications.
High-Speed Performance: Features a small friction coefficient and a high-speed limit, making it ideal for high-speed or extremely high-speed operations.
Low Maintenance: Bearings equipped with dust caps or seals on both sides are maintenance-free and lubricated for life.
Sealed Bearings: Require no additional lubrication during use. Operating temperature should be maintained between -30°C and +120°C.
Open-Type Bearings: Regular inspection and lubrication are required. Ensure the environment is clean to prevent dust and impurities from affecting performance.
Selection Advice: When choosing your bearing, consider load capacity, speed requirements, installation space, and precision requirements. Always verify that the equipment fits the 60mm x 130mm x 31mm dimension profile.
