Inline Version for 220° Adjustment
Economical-yet-rugged locking hub made of tough black thermoplastic. Adjustable Locking Hubs are rotary bearings that provide positive locking at any 10° increment. Once locked, the hub becomes an absolutely rigid joint, able to withstand considerable torque. The thermoplastic type shown here, with two square ends, can resist 33 ft-lbs of torque, with a 5:1 safety factor. Applications include adjustable fixtures, rotating fixtures, trunnion mounting, adjustable handles, foldable handles, adjustable part trays, adjustable shelves, adjustable racks, adjustable and/or fold-away work surfaces, positive positioning of lighting or nozzles, and collapsible structures. Patent numbers 5,586,363 and 5,689,999. Other patents pending. Made in the USA.
Available only as an inline version. Hub extensions line up in the same plane. The total range of movement is 220° (not a full rotation).
The version shown here has square hub extensions to fit 1-1/2" OD square tubing externally, or 3/4" square tubing or bar stock internally.
Avoid any possible pinch points, especially with heavy loads. Do not release the hub unless adequate support for the load is in place. Do not let loads swing freely.
Black thermoplastic (Dupont Zytel). DFARS and RoHS compliant.
