Welcome to our newly redesigned website!
The Zeta swivel castor with directional lock is a robust mobility solution engineered for demanding industrial applications including airport equipment, automotive original equipment manufacturing, production and platform trolleys, and transport equipment. The castor is fitted with a medium rectangular plate that provides secure attachment to host equipment. The housing comprises very heavy steel sheet construction incorporating two ball races that are either reinforced or stainless, ensuring reliable swivel performance and extended operational life in challenging environments. The wheel features a 250 mm diameter design mounted on a precision ball bearing and is fitted with an elastic tyre that is non-marking and vulcanised, with an aluminium body that balances durability with weight efficiency. The overall height of the castor assembly measures 290 mm, providing appropriate ground clearance for most industrial trolley and equipment applications. The load capacity specifications are rated at 1000 kg static load, whilst the dynamic load capacity varies according to operational speed, supporting 400 kg at 6 km/h or 500 kg at 4 km/h, allowing engineers to select appropriate deployment scenarios based on required mobility and load parameters.
