This mounted bearing is for use with a ball transfer table to provide a heavy duty conveyance system. The bearing has a 1" (25.4 mm) main ball supported by a layer of miniature balls to minimize friction. The housing is made of pressed steel for strength and resistance to corrosion, and the maximum load capacity is 75 lbs. The flange has two 5.5 mm bolt holes for mounting to a base, and measures 30.3 x 69 x 50 mm (H x W x D). These mounted bearings are suitable for use with multi-direction conveyors and feeding machines, among other applications.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed bearings are lubricated with oil or grease in the bearing factory, while open and shielded bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
