The double row deep groove ball bearing 4300 series is suitable for applications that support high speeds, radial loads, and thrust loads in both directions. The 4300 series has a larger cross section than the 4200 series, making it suitable for heavier loads and lower speeds. Because it has two rows of rolling elements, this bearing series provides a higher load carrying capacity than a single-row ball bearing.

This bearing is made of chromium steel for durability and resistance to deformity under heavy loads, and has deep inner and outer races that conform to the balls that run in them, allowing higher speeds and creating lower friction than comparable-sized roller bearings.

The open design facilitates lubricating the bearing in place and dissipating heat. This bearing has an injection molded snap-type cage made of polyamide to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This clearance provides latitude for self-realignment and compensates for static and dynamic alignment errors.

Application

This deep-groove ball bearing is suitable for commercial and industrial applications including generators, pumps, original equipment or replacement parts in motors, office automation, farm equipment, and conveyor rollers.
