Rubber Roller
A rubber roller is a cylindrical machine component consisting of a core, typically made of steel or other rigid material, covered by a layer of rubber or other elastomeric material. This design provides flexibility and grip, making them useful for a wide range of applications like printing, paper making, and conveyor systems.

Elaboration:
Core Material:
The core, or shaft, provides the structural support and is often made of steel, aluminum, or other strong materials.
Rubber or Elastomer Cover:
The outer layer of rubber or elastomer material provides the desired properties like flexibility, grip, and resistance to wear and tear.
Applications:
Rubber rollers are used in various industries including printing, paper manufacturing, textile processing, and packaging.
Key Features:
Flexibility: Allows for good contact with surfaces being processed.
Grip: Enables efficient conveyance and transfer of materials.
Wear Resistance: The rubber cover provides protection against abrasion and damage.
