roller bearing

listen to the pronunciation of roller bearing
الإنجليزية - الإنجليزية
A bearing, in which the load is carried by round (e.g. cylindrical or spherical) elements
ring of small balls that is used to support an axis that revolves inside the ring
A bearing containing friction rollers
bearings containing small metal balls
A bearing using rollers to reduce friction between machine parts. One of the two types of rolling, or antifriction, bearings, the other being the ball bearing. Like a ball bearing, a roller bearing has two grooved tracks, but the balls are replaced by rollers. The rollers may be cylinders or shortened cones. If the rollers are cylindrical, only radial loads (perpendicular to the axis of rotation) can be carried, but with conical rollers both radial and thrust, or axial, loads (parallel to the axis of rotation) can be carried. In a given space, a roller bearing can carry a greater radial load than a ball bearing can
