The Sealmaster SRP pillow block ball bearing has a rubber-mounted, stamped-steel housing with two bolt holes, a setscrew locking collar, and felt seals. This ready-to-mount unit has a solid one-piece stamped-steel housing with a rubber-mounted bearing unit. It is built for maximum strength and rigidity, with black oxide-coated bearing races for corrosion resistance. This relubricatable non-expansion-type bearing uses a setscrew locking collar for attachment to the guided shaft. A felt seal protects against contaminants and helps retain lubrication. The pillow block is suitable for carrying shafts with radial or radial-and-thrust loads and is rated for use in normal-duty applications.
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.
Sealmaster manufactures bearings and bearing accessories. The company, founded in 1938 and headquartered in Elsmere, KY, meets International Organization for Standardization (ISO) standard 9001.
