What is a plummer block?

The plummer block is a pedestal mounted bearing housing. There is a mounted block that has a bearing. In turn, the block is fixed to a base with a shaft inserted that allows the inner part to rotate. They come in different sizes and are made from cast iron or cast steel. They are designed for corrosive applications and can mount a bearing that lets the inner ring rotate while the outer one does not move.

Types of plummer blocks

The plummer blocks are of the following types:

• Split plummer blocks: They can be used for easier mounting and dismounting of the pre-assembled shafts. 
• Non-split plummer blocks: They are designed to cater to heavier loads that act in different directions. The block housing is narrow and can be used in limited spaces. 
• Flanged housings: They provide reliable housing in various applications that don’t have horizontal frames. The maintenance requirements are less too.

Applications of plummer blocks

The plummer blocks are greased and ready for installation on the equipment. They are also referred to as a housed bearing units. They find use in mechanical power transmission systems. Some of the critical applications of plummer blocks are:

• Heat treatment equipment
• Conveyor systems
• Construction plant
• Agricultural equipment
• Packaging equipment
