Plummer block bearing housings

Plummer block bearing housings – stable shaft support and UCP type bodies

Plummer block bearing housings (pillow blocks) form the foundation of most drive and conveying systems, providing rigid and secure support for rotating shafts. These mechanical components are designed for mounting on flat surfaces, such as machine frames or equipment foundations. At e-marat.pl, we offer a wide selection of plummer block housings that effectively protect the bearing from external contamination and enable high-precision lubrication of the bearing arrangement.

Among the most popular solutions, we feature ready-to-mount pillow block bearing units (e.g., UCP type). They consist of a cast iron housing and an integrated ball insert bearing. This configuration allows for rapid installation and automatic compensation for shaft misalignment, which is critical in dynamically operating production lines as well as agricultural and construction machinery.

Design types and material properties of plummer block housings

Depending on the intensity of operation and the specifics of the installation, these housings are divided into two main types:

• Split housings – consisting of a base and a cap, which facilitates maintenance and bearing replacement on long shafts without the need to dismantle the entire system.
• Non-split housings (monoblocks) – monolithic castings characterized by extreme mechanical strength, dedicated to accommodating the heaviest loads and vibrations.

The manufacturing material is of critical importance for durability – high-quality grey cast iron, spheroidal graphite cast iron, or cast steel are standard choices. Thanks to this, a plummer block housing exhibits high resistance to impacts and harsh operating conditions, such as those encountered in industrial fans, belt conveyors, and heavy-duty pumps.
