Fitted with a grey rubber tread bonded to a polypropylene core, it delivers smooth, quiet rolling across hard and semi-hard floor surfaces while protecting against surface marking and wear. With a rated load capacity of 70 kg per castor, it is well suited to trolleys, shelving units, industrial carts, workshop equipment, and commercial furniture across warehousing, retail, manufacturing, and hospitality environments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-section pc-body\"\u003e\n\u003ch2\u003eProduct Overview\u003c\/h2\u003e\n\u003cp\u003eFixed castors provide directional stability that swivel castors cannot match. By eliminating rotational movement at the head, they keep loads tracking in a straight, controlled path — an essential quality when manoeuvring heavy equipment through narrow aisles, along production lines, or across warehouse floors. This unit pairs that inherent rigidity with a grey rubber tread that absorbs minor floor irregularities, reduces rolling noise, and resists the kind of surface damage that hard plastic wheels can cause over time.\u003c\/p\u003e\n\u003cp\u003eThe pressed steel top plate, finished with a zinc-plated coating for corrosion resistance, mounts securely via four bolt holes and provides a stable, low-profile fixing point.

A swivel castor rotates 360° to allow multi-directional movement. Fixed castors are typically used in combination with swivel castors: fixed units at the rear provide straight-line stability, while swivel units at the front allow steering. For applications requiring purely directional travel, all-fixed configurations are also common.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-item\"\u003e\n\u003ch3\u003eWill this castor mark or damage my floor?\u003c\/h3\u003e\n\u003cp\u003eThe grey rubber tread is a non-marking compound, making it suitable for use on finished concrete, vinyl, timber, and tile surfaces without leaving scuff marks or residue.

The plate measures 60 mm (length) x 67 mm (width), with hole centres of 48\/38 mm and a bolt hole diameter of 6 mm. To fit, align the plate with the pre-drilled holes on your equipment base and secure using four M6 bolts (not supplied).
