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 stainless steel type shown here, with two mounting flanges, can resist 80 ft-lbs of torque, with a 5:1 safety factor. Applications include adjustable fixtures, rotating fixtures, welding 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.
Inline Version for 220° Adjustment
Offset Version for 360° Rotation
The inline version shown here has hub extensions that line up in the same plane. The total range of movement is 220° (not a full rotation).
The version shown here has mounting flanges that provide two options for mounting: 1) two 1/4-20 tapped holes allow fastening an object to the mounting flange; 2) two 9/32"-dia clearance holes for 1/4" or M6 screws allow fastening the mounting flange to a surface.
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. When using offset hubs that can rotate 360°, always ensure that loads are balanced in the rotational axis.
