Small Shock Absorbing Casters: Everything You Need to Know


Small shock-absorbing casters are used on carts and dollies to cushion their contents from impacts and vibration during transport. They reduce workplace injuries and protect sensitive tools and equipment from damage.

Shock-absorbing casters feature springs that deflect under load to minimize impact and vibration. However, not all springs are created equal, and choosing the wrong ones can negate their benefits.

They Reduce Impact and Vibration

Shock-absorbing caster wheels reduce the impact and vibration created by jolts during transportation. This protects the cargo the casters carry, saving companies money in the long run. It also helps minimize workplace injuries and improves worker productivity.

Shock absorbers are often used on carts, trucks, racks, and trolleys in medical settings, manufacturing environments, and other industries where equipment can easily be jilted. They also can help reduce noise levels and extend wheel, axle, and caster life.

Shock-absorbing casters use spring deflection to cushion the impact of bumps on uneven or damaged flooring. However, they must be adequately designed to provide the right amount of spring deflection. Otherwise, they can do more harm than good. A professional can determine the proper initial force required to cause the caster wheels to deflect. They can also recommend a caster with the suitable capacity to achieve desired results.

They Help Prevent Injuries

Carts, trucks, and racks that roll on small shock absorbing casters provide a smoother ride and protect delicate cargo. Their spring-loaded suspensions reduce the impact and vibration transferred to the equipment they carry, preventing damage to the load and reducing injuries to employees who move and relocate the equipment.

Choosing the proper spring deflection is essential. Too much or too little can negate beneficial effects, damage equipment, and cause excessive vibration.

Shock-absorbing casters are ideal for equipment dollies that can be easily jilted during transportation and used in aerospace environments where noise can interfere with communication and lead to hearing loss. These casters are relatively quiet, even with significant impacts, so they can be used in sensitive environments without disturbing operations or causing injury to employees. They also minimize the effect on the floor, extending its life and reducing maintenance costs.

They Extend the Life of Wheels and Axles

Shock-absorbing casters are designed with springs and deflect when the cart hits an irregular surface. This helps cushion the blow, minimizes noise levels, and extends wheel, axle, and caster life.

The correct spring location and deflection are crucial; too much or too little can do more harm than good. This is why it is essential to consult a professional when selecting shock-absorbing casters for an application.

While it is true that a shock-absorbing caster can help protect sensitive payloads and reduce workplace injuries, many other factors must be taken into consideration to ensure optimal performance, safety, and durability. This includes choosing an appropriately rated caster for the cart’s load, properly maintaining it, and following a regular maintenance schedule to extend its lifespan.

They Are More Expensive

Shock-absorbing casters offer many benefits, including protecting cargo from damage and minimizing noise levels in sensitive environments. They are ideal for carts and dollies used to transport equipment in environments damaged by bumps or debris, such as manufacturing environments, hospitals, or chemical labs.

Shock-absorbing casters are usually spring-loaded and deflect when pressure is applied to them. However, not all springs are created equal, and choosing the wrong one can negate these benefits. The wrong spring could be too firm and do more harm than good by creating more vibration during transportation.

Extra-heavy shock-absorbing plate casters have impact-resistant swivels with large-diameter, hardened ball bearings that make them suitable for transporting heavy equipment on rough surfaces. They have thicker steel frames and stronger kingpins than medium-duty casters and can support heavier loads. They are typically used on airport ground-support equipment and assembly line dollies in warehouses and industrial environments.
