Highly recommended for high speeds and quiet operation in wash-down or wet applications. The internal radial bearing is made from bearing grade stainless steel to prevent rust and corrosion. The bearing is assembled in the outer housing for easy installation. The hex adapter eliminates metal-to-metal contact between the bearing and axle which reduces noise during operation. The radial bearing also includes rubber contact seals for protection against dirt and debris. The seals increase rotational drag and are not recommended for gravity applications. Recommended for high speed powered conveyor applications with moderate to light loads.
