Adjustable Locking Hubs are rotary bearings that provide positive locking at any 10 Degree increment. Once locked, the hub becomes an absolutely rigid joint, able to withstand considerable torque. The stainless steel type 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. Made in USA.
The offset version has hub extensions that are offset to allow full 360 Degree 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 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 Degree, always ensure that loads are balanced in the rotational axis.
