First, divide the total loaded weight of your equipment by 4 (the number of castors) and select a castor whose individual load rating exceeds that figure — always allow a safety margin. Then check the total castor height against the clearance under your equipment frame. The 50mm castor stands 72mm tall, the 75mm stands 100mm tall, and the 100mm stands 122mm tall. If you are unsure, the 75mm option is the most versatile choice for general-purpose light-to-medium duty use.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eWill these castors mark or damage my floor?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eNo. The grey rubber tread is a non-marking compound, meaning it will not leave black scuff marks or streaks on hard floor surfaces such as vinyl, laminate, tile, or sealed concrete. The rubber tread also provides a degree of grip and cushioning, reducing noise during movement and protecting the floor from scratching. These castors are not suitable for use on soft or carpeted surfaces, where a harder wheel material would be more appropriate.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eWhat fixings do I need to fit these castors?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eEach castor is fitted with a 4-hole pressed steel top plate measuring 60mm x 60mm. The plate has two sets of hole centres — 48mm and 38mm — in both length and width directions, giving you flexibility to match existing fixing patterns on your equipment. The plate holes are 6mm in diameter, so M6 bolts, nuts, and washers are required for installation. These are standard fixings readily available from any hardware supplier and are not included with the castors.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-item\"\u003e\n\u003cdiv class=\"fc-faq-q\"\u003eCan these castors be used outdoors or in wet conditions?\u003c\/div\u003e\n\u003cdiv class=\"fc-faq-a\"\u003eThese castors are primarily designed for indoor use on smooth, hard floor surfaces. The pressed steel top plate and bracket can be susceptible to surface rust if exposed to prolonged moisture, standing water, or outdoor conditions. For occasional light exposure to damp environments — such as a covered loading bay or a kitchen area — they will perform adequately, but for regular outdoor use or consistently wet environments, a stainless steel or zinc-plated castor would be a more suitable long-term choice.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"fc-note-box\"\u003eAll castors are dispatched from UK stock. Load capacities are stated per individual castor. Always ensure the combined load rating of your chosen castors exceeds the maximum loaded weight of your equipment, with an appropriate safety margin applied.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"SafetySuppliesCo","offers":[{"title":"50mm - 60 KG","offer_id":52524419612965,"sku":null,"price":15.25,"currency_code":"GBP","in_stock":true},{"title":"75mm - 70 KG","offer_id":52524419645733,"sku":null,"price":16.85,"currency_code":"GBP","in_stock":true},{"title":"100mm - 80 KG","offer_id":52529097605413,"sku":null,"price":19.93,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/1932\/9829\/files\/100mm-Swivel-1.jpg?v=1780992596","url":"https:\/\/safetysuppliesco.co.uk\/products\/pressed-steel-swivel-castors-with-grey-rubber-on-black-polypropylene-wheel-50mm-to-100mm","provider":"safetysuppliesco.co.uk","version":"1.0","type":"link"}
