pillow block
Noun: A pillow block is a mounted housing or support that contains a bearing. Its primary function is to provide secure mechanical support and allow for the rotation of a shaft, rod, or axle. The bearing inside the pillow block reduces friction and facilitates smooth movement.
A pillow block is a fundamental component in mechanical and industrial systems. It is used to provide a stable, fixed point of support for a rotating shaft. * The conveyor belt's drive shaft is supported by two pillow blocks at either end. * For the new motor installation, you will need to align the pillow block precisely with the shaft.

The term "pillow block" is highly specific to mechanical engineering. It does not have common idiomatic or figurative meanings outside this technical context. It is not related to bedding or pillows in any functional sense; the name is derived from the block's shape or its supportive function.
