Product Description

This 6203-2RS 3/4-inch x 40x12-millimeter sealed ball bearing has deep groove geometry for high speeds and supporting both radial and axial loads. Its chrome steel construction makes it durable and resistant to deformity under heavy loads. The rubber seals on both sides of the bearing keep lubricant in and contaminants out, and it comes pre-lubricated from the manufacturer so that no additional lubrication is required. This deep-groove sealed ball bearing is for use in applications that involve combined radial and axial loads and a need for high running accuracy at high rotational speeds. Such applications include clutches, drives, gearboxes, compressors, pumps, turbines, and printing and textile machines, among others.

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.

Had a very hard time finding this bearing for a very old wood lathe head stock. When I found this bearing at Amazon after much searching, I immediately pulled the trigger on it. Afterwards I was able to source the bearing through a specialty bearing house and it was a known to be good brand. The bearing being rated here in all fairness may be adequate, but judging from the horrible smell of the grease used to pack it and the somewhat rough feel of it, I decided not to take a chance and will keep it as a backup.
