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 round ends, 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 offset version shown here has hub extensions that are offset to allow full 360° rotation. Offset hubs should usually be used in pairs, to avoid off-center loading on a single hub and ensure full strength. Make sure that rotating loads are balanced.
The version shown here has two round ends to fit 3/4" ID pipe or tubing. The tapped mounting holes can also be used to attach a plate or angle bracket.
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.
