This foot-mounted pillow block pairs a split cast iron housing with a REXNORD P2B insert ball bearing, forming a ready-to-bolt assembly for flat surfaces. It supports rotating shafts in conveyors, elevators, mixers, and process machinery where alignment and sealing matter. MR Industrial Accessories supplies this line and helps you match the right size to your shaft diameter and operating conditions.

Reading the P2B and P4B codes is straightforward once you know the pattern. The P stands for a split foot-mounted housing, the number after it gives the housing size, and the B indicates the mounting style. The next number identifies the insert bearing size and shaft diameter. A TE suffix points to a triple-lip labyrinth seal that holds grease in and keeps contaminants out. The P4B series follows the same logic but uses a higher-capacity housing. Familiarity with these codes makes replacement faster and reduces ordering mistakes when you send a request via WhatsApp.

You will find these housings in food processing plants, flour mills, feed operations, water treatment facilities, cement plants, and packaging lines. They are common on belt and screw conveyors, bucket elevators, solids mixers, and centrifugal pumps. The foot mount simplifies installation on metal structures or concrete bases, while the self-aligning insert compensates for small misalignments. The cast iron housing stands up to impact and vibration, which is why it is also chosen for dusty areas or washdown environments.

Selection starts with the shaft diameter and the type of load: radial, axial, or combined. Check that the housing provides the axial clearance you need and that the TE seal suits your dust, water, or pressure-washing conditions. During mounting, set the housing on a flat, rigid surface, tighten the fixing screws in a cross pattern, and verify alignment with a straightedge or dial indicator. Apply general-purpose lithium grease to the insert and inspect the seal lips. Poor alignment shortens bearing life and increases noise.

When you look for equivalents, remember that each manufacturer uses its own naming system for foot-mounted insert housings. The REXNORD P2B series can be cross-referenced with other brands that share shaft dimensions and bolt-hole spacing, but sealing suffixes and tolerances do not always match. For a safe replacement, send the complete code — for example P2B-211-TE — along with the shaft dimensions. MR Industrial Accessories will identify a compatible alternative or, if none exists, discuss custom manufacturing.

If you need to replace a P2B or P4B housing, contact us on WhatsApp with the code from the nameplate or with the shaft dimensions and bolt-hole distance. We will provide a quote promptly and advise on the right sealing and lubrication for your application. MR Industrial Accessories serves customers across the United States and in several Latin American countries with power transmission components and housings.
