150 × 50 mm ball-bearing swivel castor for workshop trolleys and industrial carts
The Envoy 6" x 2" Red Polyurethane (PU) plate castor is the go-to swivel wheel for workshop trolleys, utility carts, and industrial material-handling platforms that need a durable, smooth-rolling solution on concrete or tiled floors. The 150 mm diameter (6 inch) wheel with a 50 mm wide tread rolls easily over cable trays, expansion joints, and small floor irregularities without the wheel sinking or skidding — a common complaint with narrow rubber wheels on painted concrete in Northeast India's warehouses and workshops.
Polyurethane is the preferred tread material for most workshop and factory applications: it is significantly harder than standard rubber (which deforms under sustained static load, leaving flat spots), yet softer than nylon (which is loud on hard floors and can damage floor coatings). PU castors handle petrol, oil, and mild chemical spills without swelling or cracking, making them practical for garages, automotive workshops, and light engineering floors in Guwahati and across Assam. The red colour is standard for this Envoy PU grade and makes it easy to identify tread type at a glance in a mixed castor inventory.
The ball-bearing race inside the wheel hub ensures free-rolling under load with minimal push effort — important when assembling tool trolleys that are moved frequently across shifts. Fabricators and maintenance teams in Northeast India use 4–6 of these castors on heavy-gauge MS trolleys carrying welding machines, compressors, drill presses, or stacked raw material. Multi Trade Combines stocks the full Envoy plate range — from 2" light-duty to 8" heavy-duty — so you can spec every tier of your fleet from a single supplier on AT Road, Guwahati.

Welding shops and fabrication yards in Guwahati fit these castors to electrode and consumable trolleys that shuttle between welding bays. Automotive garages and tyre shops use them on tool cabinets and parts bins. Warehouse operators across Assam specify PU-wheel plate castors for picking carts and dispatch trolleys on epoxy-coated concrete. Healthcare facilities use similar PU castors on equipment trolleys for quiet, non-marking movement. If you are building or retrofitting a trolley that travels on smooth or semi-smooth floors and carries 100–800 kg total, the Envoy 150 × 50 mm PU plate castor is a solid selection.
Pairs well with: Envoy 6" x 2" Red PU Plate Brake castor (for the two fixed/braked corners of a four-castor trolley), steel angle or square-tube trolley frames, and towing handles. Multi Trade Combines carries all Envoy castor variants so a complete trolley hardware kit — four wheels, bolts, and a handle — can be sourced from a single counter visit.
The Envoy 6" x 2" (150 × 50 mm) Red PU plate castor with ball bearing is rated for medium-to-heavy trolley loads, typically in the 200–250 kg per-wheel range for standard duty. For exact rated load in your application, contact Multi Trade Combines on AT Road, Guwahati — +91 91812 13332 — specifying your trolley weight and floor surface.
A plate-type castor has a flat steel mounting plate (usually four bolt holes) that is bolted directly to the underside of a trolley frame or platform — very secure and suited for heavy fabricated trolleys. A stem or socket type inserts into a pre-drilled hole in thin-gauge tubing or furniture frames. For workshop and industrial trolleys built from steel angle or tube, the plate type is the correct choice.
