Double-row angular contact geometry for supporting both radial and axial loads Filling notches on one side to permit assembling maximum number of balls into bearing CN (normal) radial clearance for applications where thermal expansion is not a factor Pressed steel cage evenly spaces rollers for reduced friction, vibration, and noise Open bearing for lubrication applied in place

This MRC 5200-M series double-row open ball bearing has a light duty designation and is suitable for use where a single-row ball bearing is inadequate to support the radial load. Filling notches on one side permit assembling the maximum number of bearing balls into the bearing to maximize its radial load capability. The bearing’s angular contact geometry supports both radial and axial loads and its bearing races have contact angles that converge outside the bearing to increase its resistance to misalignment. It has chrome steel bearing balls, a pressed steel cage, and normal clearance. The bearing is open on both sides for lubricating the bearing in place and has a pressed steel cage to prevent the balls from coming into contact with each other during use, reducing friction, vibration, and noise. The bearing has a normal radial internal clearance designation, making it suitable for applications where the load and speeds do not result in thermal expansion. This ball bearing is suitable for use in automotive and industrial machine applications such as transmissions, motors, and pumps. 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. MRC Bearing Services manufactures ball bearings for automotive, food and beverage, energy, aerospace, and other industrial and commercial applications. The company is headquartered in Jamestown, NY.
