A Plummer Block, also known as a Pillow Block, is a robust mounting assembly that houses and supports a rotating shaft with a bearing. It is widely used in industrial applications where the shaft needs to be supported while allowing free rotation with minimal friction.
🧩 Key Features:Bearing Housing Assembly:
Consists of a housing (cast iron, cast steel, or aluminum) and an insert bearing (usually self-aligning) that supports the shaft.
Easy Installation & Maintenance:
The split housing design allows for easy mounting, dismounting, and maintenance without removing the shaft.
High Load Capacity & Rigidity:
Suitable for radial and axial loads, even in demanding and heavy-duty environments.
Sealing Options Available:
Comes with seals (felt, labyrinth, or rubber) to prevent dust, dirt, and moisture entry.
Interchangeable Components:
Bearing inserts and housings can be replaced separately, reducing downtime and cost.
