Standard 75 mm and 100 mm white replacement wheels for platform trolleys, hand trucks, and workshop carts — fits most castor housings with a standard axle pin.
The 3-inch (75 mm) and 4-inch (100 mm) white spare castor wheels are replacement wheels for platform trolleys, hand trucks, and workshop trolleys. When the original wheel on a trolley wears out, flats, or cracks, the whole trolley does not need to be replaced — only the damaged wheel. These standard-diameter white wheels fit most common castor housings with a standard axle pin, restoring the trolley to smooth, stable rolling at a fraction of the cost of a new trolley or complete castor assembly.
Multi Trade Combines stocks spare castor wheels alongside our full range of castors, platform trolleys, and material handling equipment in Guwahati. Workshops, warehouses, stores, and retail operations in Assam that use trolleys for moving goods, parts, and finished products on a daily basis are heavy users of spare wheels. A trolley with a damaged wheel is a safety hazard — it tips, veers, or jams under load — so keeping spare wheels on hand avoids disruption and maintains safe material handling in the facility.
Workshop managers in manufacturing units, garages, and engineering facilities maintain a stock of spare castor wheels for their tool trolleys, inspection trolleys, and material transfer carts. A worn wheel on a workshop trolley is usually noticed when it starts to squeak, wobble, or resist rolling — prompt replacement prevents the castors and floor from being damaged further by a flat-spotted or seized wheel.
Retail stores, supermarkets, and warehouses in Guwahati, Silchar, Dibrugarh, and Shillong use platform trolleys intensively for stock movement, and replacement wheels are a routine maintenance consumable. Hotels and hospitals using housekeeping and linen trolleys also replace wheels periodically in their facility maintenance programme.
Tea estates and their processing factories use trolleys for moving processed tea, packaging material, and spare parts within the factory floor. A stock of spare wheels prevents production delays caused by a simple wheel failure. We supply the matching castor housing, trolley platforms, and PP rope for complete material handling solutions from our Guwahati counter.

A castor wheel should be replaced when the tread (rubber or polyurethane) is worn flat or shows flat spots from overloading, when the core (nylon or metal) is cracked, or when the wheel no longer rolls smoothly even after bearing replacement. Worn wheels can jam under load, cause the trolley to deviate from its intended path, and damage smooth floor surfaces. In workshop and store environments where trolleys carry tools or finished goods, a jammed or uneven wheel causes tipping accidents. Replacement wheels are usually the more economical fix — at 75 or 100 mm diameter, the wheel is an inexpensive consumable compared to the bearing housing or the full castor.
Castor wheel dimensions (diameter and width) are broadly standard, but the bore diameter and keyway of the wheel hub must match the axle pin of the castor housing. Most 75 mm (3 inch) and 100 mm (4 inch) castor wheels are made with standard bore sizes (6 mm, 8 mm, or 10 mm pin), so a replacement wheel of the correct diameter and bore will fit the original housing. The tread material must also match the floor type — rubber for smooth workshop floors, nylon for rough surfaces, polyurethane for a balance of floor protection and load capacity. Bring the old wheel to our counter or send a photo on WhatsApp for a direct match.
