TUBE BEARERS

The tube bearer, in conjunction with rack & pinions and winches, is an integral part of the system used for pop holes, light windows, nest boxes, vents and rolling curtains. Bearers are manufactured from steel or aluminium plate and are made to order to suit your requirements. Steel bearers are manufactured from 2mm and 3mm Z275 galvanised steel strip, aluminium bearers are manufactured from 2mm thick aluminium alloy strip. This alloy strip is extruded with a 4mm edge profile to increase stiffness and reduce twist in the finished component. Bearing inserts may be specified in self lubricating, oil filled, sintered bronze or high performance Delrin co-polymer. Inserts for 1″ bearers may be specified in either material, inserts for ¾” bearers are available in the Delrin option only. The maximum recommended length varies and depends on how and where the bearer is being fixed and what load it will be carrying.
