A swivel castor rotates 360 degrees, enabling multi-directional movement. Fixed castors are typically used in combination with swivel castors — for example, two fixed at the rear and two swivel at the front — to provide both directional control and manoeuvrability. For equipment that travels in a straight line only, all-fixed configurations are common.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-item\"\u003e\n\u003cdiv class=\"pc-faq-q\"\u003eWhat floor surfaces are grey cast iron wheel castors suitable for?\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-a\"\u003eGrey cast iron wheels perform best on hard, smooth, or semi-smooth floor surfaces such as concrete, stone, ceramic tile, and sealed screed. They are not recommended for use on soft flooring, delicate surfaces, or floors where noise reduction is a priority, as cast iron wheels are rigid and can mark or damage softer materials. For sensitive floors, a rubber or polyurethane wheel would be more appropriate.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-item\"\u003e\n\u003cdiv class=\"pc-faq-q\"\u003eHow do I calculate the correct load capacity for my application?\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-a\"\u003eTo calculate the required load capacity per castor, divide the total weight of the loaded equipment by the number of castors, then apply a safety factor of approximately 1.3 to 1.5 to account for uneven load distribution and dynamic forces during movement. For example, a 300kg trolley on 4 castors requires each castor to handle at least 75kg — but with a safety factor, a 140kg-rated castor is the appropriate choice. This castor supports up to 420kg across a standard 4-castor configuration.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-item\"\u003e\n\u003cdiv class=\"pc-faq-q\"\u003eWhat does the 4-bolt-hole plate measurement mean and how do I check compatibility?\u003c\/div\u003e\n\u003cdiv class=\"pc-faq-a\"\u003eThe 4-bolt-hole plate refers to the top mounting plate with four fixing holes arranged in a rectangular pattern. The key measurements are the hole centres — the distance between the holes measured centre-to-centre — and the hole diameter. For this castor, the hole centres are 80mm (length) x 60mm (width) and the hole diameter is 9mm, on a plate measuring 100mm x 85mm. To confirm compatibility, measure the existing bolt pattern on your equipment and match it to these dimensions before ordering.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pc-footer\"\u003ePrecision-engineered for industrial performance — built to move what matters.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Castorsuk.co.uk","offers":[{"title":"Default Title","offer_id":56864442843516,"sku":null,"price":34.2,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0621\/7003\/8451\/files\/100mm_Pressed_Steel_Fixed_Castor_Grey_Cast_Iron_Wheel_4-Bolt-Hole_140kg_Load_Capacity.jpg?v=1781180518","url":"https:\/\/castorsuk.co.uk\/products\/100mm-pressed-steel-fixed-castor-grey-cast-iron-wheel-4-bolt-hole-140kg-load-capacity","provider":"castorsuk.co.uk","version":"1.0","type":"link"}
