Description
Overview:
This 48mm smooth-tube jockey wheel for Knott Avonride (MPN 800 104) is a medium duty unit for supporting and manoeuvring trailer drawbars during coupling, uncoupling and site moves. It uses a plain 48mm outer tube (approximately 1.89 in) and is specified by Knott with a 150kg static/dynamic load rating (about 330 lb). The wheel and tyre are the 200/40B type, measuring 200mm diameter by 40mm wide (approximately 7.87 in x 1.57 in), giving good ground contact for general towing and yard handling. Designed around Knott running gear, this assembly is suitable wherever a 48mm smooth-tube jockey wheel of this rating is required. Ongoing maintenance is supported via named spares: the 200/40B wheel and tyre can be replaced like-for-like, and the spindle is available separately. This makes it a practical choice for fleets and workshops standardising on Knott Avonride components where service parts must be easily sourced.
