Shock-absorbing bolt-hole casters are specialized wheel assemblies designed to reduce the impact and vibration transmitted to the equipment or furniture they support. These casters are equipped with a built-in suspension system, often utilizing springs or rubber components, to absorb shocks and vibrations. This feature is particularly beneficial in environments where equipment is frequently moved over uneven surfaces or where delicate items are transported, as it helps protect both the equipment and its contents from damage. The term "bolt-hole" refers to the mounting style of these casters. They are designed to be attached to equipment or furniture via a single bolt that fits through a hole in the caster's mounting plate. This allows for easy installation and removal, making them a versatile choice for various applications. Shock-absorbing bolt-hole casters are commonly used in industries such as manufacturing, medical, and food service, where equipment mobility and protection are crucial. They are available in various sizes, materials, and load capacities to suit different needs. The wheels can be made from materials like rubber, polyurethane, or nylon, each offering different levels of durability, traction, and noise reduction. Overall, these casters enhance the mobility and longevity of equipment by minimizing the wear and tear caused by constant movement and impact, thereby improving operational efficiency and reducing maintenance costs.

Shock-absorbing casters work by incorporating a suspension system that reduces the impact of shocks and vibrations when moving over uneven surfaces. These casters typically consist of a wheel mounted on a spring-loaded or elastomeric mechanism that absorbs energy from impacts. The key components include: 1. **Wheel**: Made from materials like rubber or polyurethane, the wheel provides traction and durability. It is designed to roll smoothly over surfaces. 2. **Spring Mechanism**: This can be a coil spring, leaf spring, or a combination of springs. The spring compresses when the caster encounters an obstacle, absorbing the energy and reducing the force transmitted to the load. 3. **Damping Element**: Often made from elastomeric materials, this component dissipates the energy absorbed by the spring, preventing excessive bouncing and ensuring a smooth ride. 4. **Swivel Mechanism**: Allows the caster to rotate 360 degrees, providing maneuverability. The swivel may also include a shock-absorbing feature to handle lateral forces. 5. **Mounting Plate or Stem**: Connects the caster to the equipment or furniture, ensuring stability and secure attachment. When the caster rolls over an uneven surface, the wheel encounters bumps or obstacles. The spring mechanism compresses, absorbing the impact energy. The damping element then dissipates this energy, minimizing vibrations and jolts. This process protects the load from damage and provides a smoother, quieter operation. Shock-absorbing casters are commonly used in environments where equipment is frequently moved over rough terrain, such as in hospitals, factories, or warehouses, enhancing both the longevity of the equipment and the comfort of the operator.
