The SEALMASTER PN Gold series 4-bolt flange housing is a mounted unit that pairs an insert bearing with a circular flange housing. It mounts perpendicular to a flat surface with four bolts, making it suitable for equipment where the shaft runs square to the support face and alignment must be straightforward.

The code CRFC-PN20RT breaks down into distinct parts: CRFC denotes the circular 4-bolt flange housing, PN refers to the PN Gold series with its sealing and retention system, 20 represents the nominal shaft diameter, and RT specifies the insert and sealing variant. Because suffixes in the PN Gold series can change the locking method or sealing, always compare the full code when specifying a replacement. If you need help, send the code CRFC-PN20RT by WhatsApp and we will point you to the compatible option.

These flange housings are common in belt conveyors, bucket elevators, mixers, blowers, centrifugal pumps and process lines across food, chemical and aggregate operations. They are often selected when the shaft must be square with the equipment wall and lubrication access is limited, since the four-bolt flange allows mounting directly onto sheet metal or structure without machining.

For correct selection, confirm the shaft diameter, the insert locking type and the sealing needed for the environment. The PN Gold series is built for conditions involving dust, humidity or frequent washdowns. During installation, set the flange on a clean, flat surface, tighten the four bolts in a cross pattern, and check shaft alignment before final torque. Lubricate according to the duty cycle and inspect the sealing if leaks appear, as a poorly seated flange can speed up bearing wear.

When interchanging mounted housings, compare shaft diameter, bolt count, center distance and insert type. Across brands, the same shaft size may differ in flange height or locking system, so matching only the shaft number is not enough. To replace a SEALMASTER unit with another brand, send us the flange measurements and insert code; we will identify a compatible alternative.
