Linear Motion 20 mm Shaft Support Block, Aluminum, Metric

This linear motion shaft support block has a 20 mm inside diameter and is suitable for end or intermittent shaft support where loads are light and shaft deflection is minimal, such as in computer numerical control (CNC) equipment. The aluminum alloy support block has a slit in the top surface to help shaft insertion, a setscrew to lock the shaft in place, and a flat square foot to help accurately align the block. This support block is light weight and is suitable for use in linear motion 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.
