A swivel castor includes a rotating head that allows the wheel to turn 360°, enabling multi-directional movement. Fixed castors are typically used in combination with swivel castors ? for example, two fixed castors at the rear and two swivel castors at the front of a trolley ? to provide both directional stability and manoeuvrability.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-item\"\u003e\n\u003cdiv class=\"cs-faq-q\"\u003eHow do I fit this castor to my furniture or equipment?\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-a\"\u003eThis castor uses a 4-bolt top plate fixing method. The pressed steel plate measures 60 mm (length) x 67 mm (width), with bolt hole centres of 48 mm or 38 mm in both directions and a hole diameter of 6 mm. To fit, align the plate with the pre-drilled holes on your furniture or equipment frame and secure using four M6 bolts (not included). Ensure the mounting surface is flat and structurally sound to achieve the rated load capacity.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-item\"\u003e\n\u003cdiv class=\"cs-faq-q\"\u003eIs this castor suitable for use on hard floors such as tile, concrete, or laminate?\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-a\"\u003eYes. The polypropylene wheel is well suited to smooth, hard floor surfaces including tile, sealed concrete, vinyl, and laminate. It rolls quietly and does not leave marks under normal operating conditions. It is not recommended for use on soft or uneven surfaces such as carpet, gravel, or outdoor terrain, where a softer wheel material would be more appropriate.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-item\"\u003e\n\u003cdiv class=\"cs-faq-q\"\u003eHow many castors do I need, and what is the combined load capacity?\u003c\/div\u003e\n\u003cdiv class=\"cs-faq-a\"\u003eEach castor is rated to carry 65 kg. When four castors are used together, the combined maximum load capacity is 195 kg. Note that the combined figure is not simply four times the individual rating ? a safety margin is applied to account for uneven load distribution across the four mounting points. Always ensure the total weight of the loaded item does not exceed 195 kg when using a set of four of these castors.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp class=\"cs-note\"\u003e* All measurements are nominal.
