Linear Motion 20 mm Slide Unit, Open Type, Metric

Linear Motion 20 mm Slide Unit, Open Type, Metric

This linear motion open type slide unit has a 20 mm inside diameter and is suitable for use in precision linear motion applications, such as in printing machines and computer numerical control (CNC) equipment. The open type aluminum alloy housing and ball bushing insert provide shaft support clearance. The slide unit, designed to carry a component, has a housing with a flat mounting face and four tapped bolt holes, and circle clips at each end to retain the ball bushing. The ball bushing insert compensates for misalignment caused by tolerance defects and mounting errors. The linear motion ball bushing insert has a chromium steel bushing case for strength and rigidity, a synthetic resin retainer plate for accurate ball guidance and low noise, five rows of recirculating balls inside the ball bushing for smooth running, and a maximum operating temperature of 80 degrees Celsius/176 degrees Fahrenheit. This slide unit can carry a load accurately along a straight line and is suitable for 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.
