This makes it ideal for straight-line movement and directional stability. A swivel castor can rotate 360 degrees, allowing the platform to be steered in any direction. Most trolleys and platforms use a combination of both: fixed castors at the rear for stability and swivel castors at the front for manoeuvrability.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-item\"\u003e\n\u003cdiv class=\"cs-faq-q\"\u003eWill these castors scratch or mark my floor?\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-a\"\u003eThe grey rubber tread is a non-marking compound suitable for use on hard indoor floor surfaces including timber, vinyl, laminate, tile, and sealed concrete.

The 50mm option suits lighter domestic and furniture applications up to 60 kg per castor. The 75mm option is well suited to workshop, retail, and light commercial use up to 70 kg per castor. The 100mm option is the best choice for heavier industrial and commercial equipment up to 80 kg per castor, and also rolls more easily over minor floor irregularities due to its larger diameter.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-item\"\u003e\n\u003cdiv class=\"cs-faq-q\"\u003eAre these castors sold individually or in sets?\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-a\"\u003eThese castors are listed and priced individually.
