50mm/2in PU Braked Swivel Castors Set of 8, Bolt Fixing, Ball-Bearing

• Bolt-through fixing with hardware included – Supplied with M8 x 20 mm bolts, nuts and washers for secure mounting through pre-drilled panels or frames. Ideal for metal, thin panels and other surfaces where both sides of the mounting point are accessible.
• 50 kg / 110 lb capacity per caster – Each 2 in caster supports up to 50 kg / 110 lb. A four-caster base supports up to 200 kg / 440 lb on a flat floor, while the recommended working load on three casters is 150 kg / 330 lb for uneven-floor conditions.
• Smooth 360° swivel with total-lock brake – Precision ball bearings deliver smooth, quiet and low-effort rolling, while the total-lock brake secures both the wheel and swivel to help keep trolleys, workbenches, cabinets and other equipment firmly in position.
• Non-marking polyurethane tread – Durable PU wheels roll without leaving black marks or scuffs on hardwood, laminate, tile, vinyl, epoxy or polished concrete. The tread also resists oils, greases and many common workshop chemicals.
• Set of 8 for carts, furniture and workbenches – Includes 8 braked swivel casters with black powder-coated steel brackets for strength and corrosion resistance. Suitable for utility carts, furniture, workbenches, cabinets, toolboxes, display units and other mobile equipment.

FIXING TYPE: BOLT-THROUGH. Supplied with M8 x 20 bolts, nuts + washers to bolt through a pre-drilled panel or frame.

Wheel Size: Ø50 x 22.8 mm (2" x 7/8") Overall Height: 71 mm Top Plate: 52 x 72 mm with 4 slotted holes (Ø8.3 mm) Bolt-Hole Centres: 35 x (49-55) mm (slotted for flexible fixing) Load per castor: 50 kg / 110 lb Total load on 4 castors (flat floor): 200 kg / 440 lb Safe working load on 3 castors (uneven floor): 150 kg / 330 lb Pack of 8 = up to 400 kg / 880 lb combined Motion: 360° swivel with total-lock brake (locks wheel + swivel) In the box: 8x swivel castors with total-lock brake; supplied with M8 x 20 bolts, nuts + washers Why the 3-castor rating matters: floors are rarely perfectly level, so a loaded trolley usually rests on only three of its four castors at any moment. Size your load to the 3-castor figure (150 kg) for a safe margin, not the flat-floor maximum. FREGAT Series 65 castors roll on hard-wearing polyurethane (PU) tyres fitted with precision ball bearings for an easy, quiet, low-effort roll. The PU tread is non-marking and leaves no scuffs or black marks on hardwood, laminate, tile, vinyl, epoxy or polished concrete. PU shrugs off oils, greases and most workshop chemicals and resists wear far better than soft rubber, so the wheels last longer and run more smoothly under load. The wheel core is tough white hard PP (polypropylene) plastic, while the swivel fork and top plate are black powder-coated steel for strength and corrosion resistance. Ideal for trolleys, furniture, workbenches, carts, cabinets, display units, toolboxes and DIY projects.
