The CRTBF-PN pillow block from SEALMASTER serves as the mounting base that holds and aligns a mounted bearing wherever the load acts at a right angle to the shaft. Conveyors, ventilation equipment and process machinery commonly rely on this type of unit because it mounts easily and holds up under demanding duty. MR Industrial Accessories LLC supplies this series along with technical guidance to help you match the housing to your shaft and load.

Break the code down and it tells you what you are looking at. The letters CRTBF point to the SEALMASTER pillow block family, PN marks how the unit mounts, and the trailing digits give the size. So CRTBF-PN12, CRTBF-PN16 and CRTBF-PN20 are three sizes belonging to one series. Those digits are a size code, not a shaft measurement, so they have to be checked against the manufacturer's size table before you order. The safest way to request a quote is to copy the full part number printed on the equipment or stamped on the housing.

You will run into these housings on belt conveyors, bucket elevators, mixers, blowers and process lines in food, chemical and aggregate operations. Sites dealing with dust, moisture or regular washdown tend to favor them, since a rigid base keeps the bearing aligned and absorbs vibration. Choose the CRTBF-PN when the mounting is the pillow block type, the shaft runs parallel to the base, and the radial load lands on the housing.

Sizing comes down to a few basics: shaft diameter, which mounted bearing the housing carries, the direction of the load, and the conditions on site. Set the base flat on the structure rather than packing it with makeshift shims, and tighten the mounting bolts to the recommended torque. Where dirt or water is present, inspect the bearing seal and the state of the grease as part of your routine. Lubrication and internal clearance belong to the bearing, not the housing, but a base that sits out of alignment will speed up wear across the whole assembly.

On a replacement job, match the complete part number first, then confirm the critical dimensions: hole spacing, height to shaft center and housing diameter. Cross-brand equivalents do exist, yet they are never automatic, because two housings can share dimensions and still differ in tolerances or in how they fasten. Send us the original part number and a photo of the part, and we can point you to a compatible option. Our team works with leading brands and knows the assemblies used throughout US industry and in several Latin American countries.
