5 Surprising Facts About Casters Every Professional Should Know

Casters simplify the movement of heavy or bulky items. By attaching a wheel to a mounting plate, they convert lifting into rolling, saving time and reducing strain. Though the concept is familiar, many users overlook the nuanced engineering behind these seemingly simple devices.

#1) Swivel Casters Are Over a Century Old

Swivel casters, which rotate 360°, have been in use for over a century. The first patented design was created by Seibert Chesnutt, and a modern patent was filed in 2020.

#2) Some Casters Feature a Locking Mechanism

Many casters—both swivel and fixed—include a locking mechanism that prevents movement when engaged. On uneven surfaces or ramps, this feature acts as a brake, keeping the load stationary and enhancing safety.

#3) Casters Suffer From ‘Flutter’

Flutter, also called shimmy, occurs when a caster oscillates side‑to‑side, compromising stability. The problem is mitigated by installing dampers—washers positioned around the swivel joint—to absorb motion.

#4) Lower Risk of Injury

Casters reduce the need for manual lifting, a common source of workplace injuries. By enabling rolling rather than hoisting, they lower the risk of back strains and other injuries that affect thousands of workers annually.

#5) Available in a Variety of Materials

Casters are engineered from multiple materials: the wheels are typically made of durable plastics or rubber, while the frames are forged from metal or alloy. This combination offers both resilience and load‑bearing strength.
