Thrust Ball Bearing - 51300 Series

• 51300 Series.

About Thrust Ball Bearing

• Thrust ball bearings are divided into single and double direction types.
• The former is able to accommodate axial load in one direction, while the latter is able to accommodate it in both directions.
• Neither is suitable for applications that involve radial load or high-speed rotation.
• Bearings whose housing race back face is spherical (with a spherical back face or aligning seat race) are designed with a self-aligning capability and can accommodate the effects ofinaccurate mounting.

Main Applications

• Automobile steering pivots and machine tool spindles.

Features of Ball Thrust Bearing

• Consists of a row of balls running between two grooved washer rings.
• The smaller bore ring is referred to as the shaft washer while the larger bore ring is called the housing washer.
• The ring faces are always mounted parallel to the shaft centerline.
• The housing washer is made with either a flat or spherical back face.
• Thrust bearings with spherical faces and washers are self-aligning to compensate for mounting errors.
• Cages can be pressed steel, copper alloy, and a synthetic resin molded or machined resin cage
