Ideal Applications This versatile swivel castor with directional brake is perfectly suited for: Industrial trolleys and material handling carts Workshop equipment and mobile workbenches Medical equipment stands and hospital trolleys Food service equipment and catering trolleys Warehouse storage units and picking carts Laboratory furniture and mobile storage cabinets Retail display units and merchandising stands Educational furniture and mobile classroom equipment Cleaning equipment and janitorial carts Office furniture and mobile filing systems Frequently Asked Questions What is the difference between a directional brake and a total lock brake? A directional brake locks only the swivel mechanism, allowing the wheel to continue rolling in a straight line. This is ideal for controlled movement along corridors or aisles. A total lock brake stops both the swivel and the wheel rotation completely, preventing any movement. What type of floors is this castor suitable for? The white nylon wheel is non-marking and suitable for most hard floor surfaces including concrete, tile, vinyl, laminate, and sealed wood. It provides excellent floor protection whilst maintaining smooth rolling performance. How do I calculate the total load capacity I need? Calculate the total weight of your equipment plus the maximum load it will carry, then divide by the number of castors. Add a 25-30% safety margin. For example, for a 400kg total weight on 4 castors: 400kg ÷ 4 = 100kg per castor, plus 30% safety margin = 130kg minimum capacity required. What fixings do I need to mount this castor? The 4-hole top plate requires four M10 bolts or screws with appropriate washers and nuts. The 11mm holes accommodate M10 fixings with clearance. Ensure fixings are suitable for your mounting surface material and thickness. Can this castor be used outdoors? Whilst the zinc-plated steel construction offers some corrosion resistance, this castor is primarily designed for indoor use. For outdoor applications or high-moisture environments, consider stainless steel alternatives for enhanced durability. How does the ball journal bearing improve performance? Ball journal bearings use precision steel balls to reduce friction between the swivel mechanism and the mounting plate. This results in smoother rotation, easier manoeuvrability, reduced wear, and extended service life compared to plain bearings. What maintenance does this castor require? Regular maintenance includes removing debris from the wheel and swivel mechanism, checking mounting bolts for tightness, inspecting for wear or damage, and applying light lubrication to the bearing assembly every 6-12 months depending on usage intensity. How many swivel castors should I use on my equipment? For optimal manoeuvrability, use four swivel castors. For better straight-line stability, use two swivel castors at one end and two fixed castors at the opposite end. The swivel castors should typically be positioned at the end where you push or pull the equipment.
