Definition

1. Noun:
   • A mechanical component: "plummer-block" is a type of bearing housing, specifically a split or solid block that supports a rotating shaft. It is commonly used in machinery to reduce friction and provide stable support for shafts, often in industrial or engineering contexts.

Usage Examples

• Noun:
  • The engineer replaced the damaged plummer-block to ensure the conveyor belt ran smoothly. (The bearing housing was changed to keep the rotating shaft stable.)
  • A plummer-block is essential in heavy machinery for supporting long shafts. (This component provides crucial support in equipment with extended rotating parts.)

Advanced Usage

• "to mount a plummer-block": to install or position the bearing housing in a machine.

  • The technician mounted the plummer-block securely on the base plate. (The housing was fixed in place for the shaft to rotate without wobbling.)

• "split plummer-block": a type of plummer-block that can be separated for easier maintenance or shaft replacement.

  • The split plummer-block allows quick access to the bearing without disassembling the entire system. (The separable design simplifies repairs.)
