A swivel castor has a rotating head that allows the wheel to turn 360 degrees, enabling multi-directional movement. Fixed castors are typically used in combination with swivel castors on the same piece of equipment: the fixed units provide directional stability while the swivel units allow steering.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-block\"\u003e\n\u003cdiv class=\"pd-faq-q\"\u003eWill this castor protect my floors from scratches or marks?\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-a\"\u003eYes. The grey rubber tread bonded to the polypropylene wheel core is specifically designed to be floor-friendly. The soft rubber compound absorbs surface irregularities, reduces rolling noise, and minimises the risk of scuffing or marking hard floor surfaces including timber, vinyl, tile, and sealed concrete. It is not intended for use on very soft or unfinished surfaces where the wheel may sink or leave impressions.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-block\"\u003e\n\u003cdiv class=\"pd-faq-q\"\u003eHow do I fit this castor to my equipment?\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-a\"\u003eThis castor uses a 4-bolt-hole top plate fixing method. The zinc-plated pressed steel plate measures 60mm (length) x 67mm (width), with bolt hole centres of 48mm \/ 38mm on both axes and a hole diameter of 6mm. To fit, align the plate over your mounting surface, mark and drill four 6mm holes at the correct centres, then secure with appropriate bolts (not supplied). Always ensure the mounting surface is structurally sound and capable of supporting the intended load.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-block\"\u003e\n\u003cdiv class=\"pd-faq-q\"\u003eHow many castors do I need, and what is the total load they can support?\u003c\/div\u003e\n\u003cdiv class=\"pd-faq-a\"\u003eEach castor in this range is rated to 80kg individually. When four castors are fitted to a single piece of equipment, the combined maximum load capacity is 240kg — not 320kg — as a safety margin is applied to account for uneven load distribution across the four mounting points. For equipment that will regularly carry loads close to the maximum, we recommend selecting a castor with a higher individual load rating to maintain a safe working margin.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"pd-closing\"\u003e\n\u003cstrong\u003ePrecision-engineered for dependable performance.\u003c\/strong\u003e This fixed castor is built to deliver consistent, low-maintenance mobility across a broad range of commercial and industrial applications.
