This is a Fixed Auction for a New in the Box, Thomson Precision 1/2" Ball Bushing Bearings, No. A81420. PLEASE NOTE -- Each Bid is for ONE Bearing. Closed Type, Precision, Hardened Steel, Inch, Hardened Steel, 7/8" OD, 1-1/4" Length Precision Linear Ball Bushing Bearing, Bore Diameter 0.50 Inch, Length 1.250 Inches, Bearing Diameter 0.8750 Inch, Load Capacity 85/60 Pounds, Distance between Grooves 0.967 Inch, Required Housing Bore Diameter 0.8755 Inch, Closed Type, Steel Precision Steel Ball Bushing bearings offer great improvements in efficiency, productivity, and accuracy over high-friction plain bearings flat-ways. The all-steel design makes the bearing product line perfect for replacing plain bearings in high temperature applications. Rigid construction makes them very durable compared to ball bushing bearings with polymer components. When installed in a standard Thomson Pillow Block, the Precision Steel Ball Bushing bearing can self-align up to 3° in all directions. Product Features Linear ball bearing for low-friction linear movement on a shaft Hardened steel outer sleeve for strength and resistance to wear Chrome steel balls for high load capacity and resistance to wear Recirculating balls reduce wear and coefficient of friction Low coefficient of friction allows the use of smaller motors and drive components This Thomson Precision series open type ball bushing bearing provides free linear movement on a hardened steel shaft. Ball bushing bearings are linear ball bearings that reduce friction for linear motion. The bearing’s outer sleeve is made of hardened 52100 steel for strength and resistance to wear, and the balls are made of chrome steel for high load capacity and resistance to wear. The balls are recirculated to reduce wear and provide a low coefficient of friction, allowing the use of smaller motors, belts, and gears compared to conventional linear bearings. The bearing has a maximum operating temperature of 500 degrees F (260 degrees C). This ball bushing bearing is shipped with a rust preventative oil, and is used in XY tables and other types of motion control equipment. Plain bearings provide low-friction sliding contact for relative motion between parts of a machine. They are the simplest type of bearing, with no rolling elements, and there are three basic types of plain bearings: radial plain bearings (also called sleeve bearings or bushings) to support rotating or reciprocating shafts, thrust bearings (also called washers) to support axial loads on shafts, and linear bearings to support and guide the motion of parts in a straight line. Flanged sleeve bearings have a flange on one end to support axial loads. Spherical plain bearings are radial bearings that allow for angular misalignment of the shaft. Plain bearings are made from durable, low-friction materials such as sintered or cast bronze alloys, plastic, or a combination of a metal shell and a plastic bearing surface. They can be lubricated externally or by a lubricant embedded in the bearing material. Plain bearings are used in automobiles, construction and mining equipment, textile manufacturing equipment, and robotics, among others. Many more sizes available - see my other auctions. I will fully guarantee these Bearings.
Shipping in the Continental US is $3.90 - I have very competitive rates for International bidders that are always welcome.
