The Alpha swivel castor has a bolt hole fitting and a housing made of heavy steel sheet. It features a two ball races swivel bearing that allows the wheel to rotate 360 degrees. The wheel body is made of polyamide with a non-marking, vulcanized elastic tire tread. The wheel uses a roller bearing and has a diameter of 125 mm. The overall height of the castor is 155 mm. At a speed of 4 km/h, the Alpha castor has a load capacity of 160 kg. Under static load conditions, it can support up to 320 kg. The bolt hole fitting and heavy steel housing provide durability while the polyamide wheel with elastic tire tread allows for smooth rolling and non-marking mobility across various surfaces. With its high load capacities both dynamic and static, 360 degree rotation, and heavy duty construction, the Alpha is an ideal heavy duty swivel castor.
