Bearing Units - Plummer Block & Accessories

Plummer blocks, also called pillow blocks, are powerful bearing housings built to provide sturdy support to rotating shafts in challenging industrial applications. They are usually utilised with larger-diameter shafts and heavier loads than other types of bearing units. They feature a split housing designed to facilitate easy installation and maintenance, which makes them perfect for various applications across different industries.

Crucial Components of Bearing Units - Plummer Block & Accessories

A complete plummer block unit is generally composed of the following:

• Plummer Block Housing: A robust cast iron or cast steel housing that provides necessary support to the bearing and offers mounting points. 
• Bearing: Typically, a spherical roller bearing or self-aligning ball bearing is preferred because it can accommodate shaft misalignment.
• Seals: Stops contaminants from penetrating the bearing and retains lubricant. Common seal types include felt seals, labyrinth seals, and heavy-duty taconite seals.
• Lubrication System: Supplies for grease or oil lubrication, including grease nipples or oil inlets.

What are the Popular Plummer Block Housing Types?

Plummer block housings come in different designs to address various applications:

• Split Plummer Blocks: They allow for easy installation and removal of the bearing without disassembling the entire shaft.
• Solid Plummer Blocks: Used in applications where the shaft can be inserted axially.

Crucial Accessories for Plummer Block Units

Several accessories improve the overall performance of plummer block units, including:

• End Covers: Shield the bearing and housing from pollutants.
• Locating Rings: Position the bearing axially within the casing.
• Adapter Sleeves: Facilitate mounting bearings with tapered bores onto cylindrical shafts.
