Choose industrial castor wheels by four factors: load capacity (total load divided by number of castors), wheel material (polyurethane, nylon, rubber or cast iron depending on floor and environment), floor type (smooth concrete, grating, tiles) and mobility requirement (fixed, swivel or swivel-with-brake). Multi Trade Combines stocks industrial castors and trolleys in Guwahati.
Load, material, mobility type and mounting
Step 1 — Calculate load per castor: Total load (kg) ÷ number of castors × 1.25 safety factor. Never pick a castor exactly at its rated limit.
Step 2 — Choose wheel material for your floor:
Step 3 — Choose swivel or fixed: Use 2 swivel + 2 fixed for straight-line trolleys; 4 swivel for full manoeuvrability; add brakes on swivel castors when the trolley must be parked on a slope.
Step 4 — Check mounting plate or stem: plate-mount (bolt through flange) suits custom frames; stem-mount (threaded or push-in) suits standard tube frames.

Workshops, hospitals, warehouses and mobile equipment
Multi Trade Combines supplies castors for a wide range of industrial and commercial applications in Assam and the Northeast:
If your application is unusual — extreme temperature, corrosive chemicals, explosive atmosphere (ATEX) — call us to discuss the right specification.
Divide the total maximum load (equipment + contents) by the number of castors, then select a castor rated for at least 20–25% more than that figure to allow for uneven floors and dynamic shock loads. For example, a 500 kg trolley on four castors needs each castor rated for at least 150 kg. Multi Trade Combines on AT Road, Guwahati stocks castors from light-duty 50 kg to heavy-duty 2,000 kg+.
Polyurethane (PU) castors are the most popular for smooth concrete factory floors — they roll quietly, protect the floor from marks and handle moderate loads well. For rough or outdoor surfaces use rubber castors. For high-temperature or chemically aggressive environments use nylon or cast iron. For very heavy loads on smooth floors, steel-core PU castors are the standard choice.
