Product Description

This linear motion closed type ball bushing has a 20 mm bore, a double length case, and a square case flange, and is suitable for use in a mounted slide unit to carry components in precision linear motion applications, such as in printing machines and computer numerical control (CNC) equipment. This ball bushing insert is used where shaft support clearance is not a factor and it compensates for misalignment caused by tolerance defects and mounting errors. The linear motion ball bushing has a flanged chromium steel case for strength and rigidity, two synthetic resin retainer plates set in tandem for accurate ball guidance and low noise, five rows of recirculating balls guided by each retainer plate for smooth running, seals at each end to retain lubricant and protect against contamination, and a maximum operating temperature of 80 degrees Celsius/176 degrees Fahrenheit. As part of a linear motion system, this long ball bushing can carry a load accurately along a straight line and is suitable for use in applications, such as measuring systems, printing equipment, and CNC tools.

Mounted bearings combine a bearing mounted inside a housing unit. The bearing housing replaces the need for a casting or weldment to position the bearing securely for reliable operation, and its design determines the type of insert bearing. Insert bearings use rolling elements (ball, cylindrical, spherical, barrel, needle, spindled, or tapered) to maintain the separation between moving parts to reduce rotational friction, and to support radial and axial loads. Available in a variety of materials and mounting configurations, mounted bearings can be one- or two-piece, they can have an extended inner ring and locking device, and they can have seals and end caps that retain lubrication and protect the working parts of the bearing from environmental debris. Mounted bearings support shafts in a variety of mounting configurations (flange block, hanger, pillow block, and take-up block), and are used in a range of applications from light duty shaft guidance on conveyors to road building equipment and crushers.

Nice linear bearing with a decent sized flange. The external diameter is 28mm as specified and it working in the leg vice I am using now. This review should be updated in a year or so to see how the bearing stands up to abuse!
