Metal wheels or heat-resistant plastic wheels are suitable for high-temperature conditions. Avoid standard rubber wheels, as elevated temperatures can cause rubber to soften, deform, or even melt.

The noise reduction effect primarily depends on the wheel material and bearing quality. Polyurethane and rubber wheels are generally quieter than nylon wheels, while high-quality bearings also minimise friction noise.

Possible causes include bearing damage, bracket deformation, debris obstructing the wheel, or improper installation. Inspect and clear any obstructions; replace damaged components if necessary.

Regularly clear debris from wheels, check bearings for lubrication needs, tighten bracket screws, and promptly replace worn wheels to extend service life.

Soft surfaces (carpets) suit large-diameter hard wheels, while hard surfaces (tiles) favour elastic wheels to reduce noise and vibration. Uneven surfaces require large-diameter castors.

Load capacity is typically determined by multiplying the rated load per castor by the number of castors, then applying a safety factor (generally 1.3–1.5). For example, four castors rated at 100kg each should not exceed a total load of 300kg.

Brake castors can lock the wheel when required, preventing equipment from sliding. Common braking methods include wheel-face brakes and full brakes (simultaneously locking the wheel and steering mechanism), suitable for scenarios requiring fixed positioning.

Common materials include polyurethane (PU), rubber, nylon, cast iron, and plastic. PU castors are quiet and wear-resistant, rubber castors offer good shock absorption, nylon castors have high load-bearing capacity, while cast iron castors are durable but heavier.

Castors are primarily categorised into fixed castors and swivel castors. Fixed castors can only roll in a single direction, making them suitable for straight-line movement; swivel castors can turn 360 degrees, facilitating flexible manoeuvring.

Castors are wheel assemblies fitted to the base of furniture or equipment to facilitate movement, typically comprising a wheel, bracket and bearing. They are widely used in trolleys, toolboxes, medical equipment, shelving and similar items, enabling effortless movement by reducing friction.

When choosing castors, factors such as load-bearing requirements, floor surface material, ambient temperature, and whether silent operation is needed must be considered. For instance, silent polyurethane castors are suitable for hospitals, while nylon castors are appropriate for factory floors.

The installation height is the sum of the wheel diameter and the bracket thickness. Excessive height compromises stability, while insufficient height may increase rolling resistance. Selection should be based on the equipment's application and ground conditions.
