Thomson SPTWNM25 Ball Bushing Pillow Block Bearing, 4 Bolt Holes, Closed Type, Twin Bearing Version, Metric, 25 mm Bore Diameter

Description

The Thomson super series metric twin ball bushing bearing pillow block has integral lip seals and a removable housing cap. The four-bolt ductile iron housing with two steel ball bearing inserts provides ready-to-mount installation. The split housing with removable housing cap helps with mounting, inspection, and maintenance. The integral lip seals protect against contamination and help retain lubricant. The closed-type pillow block can be relubricated if necessary and is suitable for spanning or bridging a gap. 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.Thomson Linear Motion manufactures control, drive, motor, power transmission and precision linear motion technologies.
