The Envoy 2-inch polyurethane plate castor is a compact, light-duty swivel wheel for workbenches, trolleys, and equipment bases — Multi Trade Combines stocks it in Guwahati, price on request.
This 50 mm diameter polyurethane swivel castor uses a flat plate fitting — four bolt holes on a standard pitch pattern — making it easy to retrofit to existing trolleys, workbenches, equipment skids, and storage cabinets without custom fabrication. The PU tread bonded to the steel hub gives a good balance of rolling ease, floor protection, and chemical resistance.
Light-duty castors of this size are the workhorse of small fabrication shops across Northeast India. Welding shops in Guwahati's Industrial Area use them on weld-positioner bases; auto-garages roll tool cabinets and parts trays around on them; electrical contractors mount cable-drum stands on plate castors. Tea estates fit them to plucking-basket trolleys and field-maintenance carts. Even institutional kitchens and hospital service areas specify PU castors for their quiet, hygienic roll on tiled floors.
The plate-fit design means no axle drilling is required — just bolt the castor plate to any flat surface. Two swivel castors at the push end and two fixed castors at the pull end is the standard trolley layout for directional stability, though four swivel castors suit workbenches that need 360° mobility.
For heavier loads on the same trolley frame, the Envoy 3-inch Red PU Castor (also stocked at Multi Trade Combines) steps up capacity significantly. Pair with hand pallet trucks for yard-level handling, or chain pulley blocks for vertical lifts at the workstation. We also carry flat-plate castor brackets and locking-pin castors for applications where the trolley must be immobilised during machining or assembly.

A standard 2-inch (50 mm) polyurethane plate castor in the Envoy light-duty range typically carries 40–60 kg per wheel. For a 4-castor trolley or workbench that is adequate for tool cabinets and light workshop fixtures. Heavier loads need 3-inch or larger castors with ball-bearing hubs.
Polyurethane wheels roll quietly on concrete and tile floors, resist oil and solvent contamination common in workshops, and leave no black marks unlike rubber. They last longer than standard rubber on abrasive floors and offer better load distribution than hard nylon on uneven factory surfaces.
