This DAC30550032 wheel bearing is made of carbon steel, is double shielded, and has a steel cage. It has a 30 mm inside diameter, a 55 mm outside diameter, and a 32 mm depth. This double-row ball bearing has deep groove geometry for applications that require high speeds and support both radial and axial loads. This bearing's inner and outer races are made of carbon steel for durability and resistance to deformity under heavy loads. It has Normal radial internal clearance for applications that do not involve thermal expansion or atypical precision. This ball bearing conforms to ABEC 1 precision standard for performance within a narrow range of variation. Metal shields on both sides of the bearing keep the lubricant in and contaminants out. The steel cage evenly spaces rollers for reduced friction, vibration, and noise.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and 30x55x32 Bearing 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 NSK 6006du Bearing 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.
