The SEALMASTER CRTBF-PN is a mounted bearing assembly that pairs an insert bearing with a pillow block housing, ready to bolt onto a bed or frame. It supports rotating shafts where a firm, straightforward support is needed. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams across the United States and Latin America.

Reading the code helps you order the right replacement. CRTBF-PN identifies the pillow block series, which may come with a split or solid housing depending on the variant. The PN suffix tells you how the insert locks onto the shaft, typically by set screws or clamps. The trailing number, such as 20 or 32, reflects the shaft diameter in millimeters or inches per the manufacturer's convention. So CRTBF-PN20R and CRTBF-PN32R sit in the same family but fit different shaft sizes.

You will find these units on conveyors, mixers, mills, pumps and industrial fans. They suit food plants, cement operations, tanneries and water treatment systems, including humid or dusty areas. The pillow block shape mounts flat and handles moderate radial and axial loads.

Selection comes down to shaft diameter, load type and the surrounding environment. Look at the sealing: single or double lip variants offer more protection from contaminants. Factory lubrication may need topping up based on the duty cycle. During installation, line up the housings so the shaft is not stressed, and tighten the set screws in a controlled way to keep the insert from slipping.

Mounted bearings from different brands can often be swapped when the key dimensions line up: shaft diameter, mounting height and hole spacing. Series with matching suffixes usually share geometry, but always confirm the exact code and tolerances. We can point you to a compatible alternative that will not disrupt your equipment.
