Radial bearings are those with rolling contact in which the direction of action of the load transmitted is radial to the axis of the shaft. This bearing reduces rotational friction and support loads. The ball offers substantially less rolling resistance and coefficient of friction than if two flat surfaces were rotating. Features: VERSATILE: Recommended for applications in which high loads, high speeds, and extreme temperatures are factors GREASE-PACKED: Parts come pre-lubricated for ease of use REDUCES FRICTION: Radial bearings reduce the risk of damage due to rotational friction and rolling resistance DESIGNED FOR RADIAL LOADS: These bearings accommodate loads that run predominantly perpendicular to the shaft These radial bearings feature an attractive bronze finish, come bagged in quantity of 1, and measure 1/2" in inner diameter (bore) x 1-3/8" outer diameter
