The Zeta fixed castor features a medium rectangular plate fitting for secure mounting applications. The housing is constructed from steel sheet, very heavy grade material, providing robust structural integrity for demanding industrial environments. The wheel incorporates a polyamide body with tread material identical to the wheel body, ensuring consistent performance characteristics, whilst utilising a plain bearing system for reliable operation. The wheel diameter measures 250 mm, contributing to smooth movement across various surfaces. The overall height of the complete assembly is 290 mm, making it suitable for applications requiring substantial ground clearance. Load capacity specifications include a static load rating of 1600 kg, with dynamic load capacities of 800 kg at 4 km/h operating speed and 640 kg at 6 km/h operating speed, ensuring reliable performance across different operational requirements.
