Fairlane Products, a North American manufacturer and supplier of material handling components, workholding technologies, fixturing accessories, and machine tool components, has expanded its lineup of workholding and fixturing components with a wide range of adjustable grippers.
Adjustable grippers penetrate the work piece to provide superior holding power. Used in jigs, fixtures, and chuck jaws, these grippers fit any number of applications. Adjustable grippers are available in high-speed tool steel, with either tool steel or carbide serrations, in several thread styles and lengths. The styles include carbide-tipped hex head, carbide-tipped round head, and threaded body type, as well as many tooth patterns such as smooth, fine, extra fine, straight, and diamond. Each allows the user to adjust the height of the gripper. They’re for workholding applications where limited access space, or limited fixture travel makes loading, unloading, and secure holding difficult.
In the hex head style, the serrated round carbide pad is brazed into hex head pocket, while the threaded body and hex allow height adjustment. The hex head version is available in many tooth pattern serrations pad styles, in inch and metrics sizes. With shank lengths ranging from 1/2" to 2-1/2" and 12mm to 60mm. Pad diameters from 5/16" to 1" and 10mm to 30mm.
A version of the hex head is the Adjustagrip Gripper. This version is like the adjustable hex head, but with added benefits with a replaceable pad (fits only a 3/8" round gripper that has a tapped-thru hole). The Adjustagrip allows for height adjustment and comes in an alloy steel body and a blind internal hole in the back for backside mounting. The Adjustagrip comes in inch sizes only.
The round head gripper type provides a serrated round carbide pad brazed into a hex head pocket. The threaded body and flat pad allow for height adjustment. Available in inch sizes only, round head adjustable grippers are in shank sizes from 9/16" to 2-1/2" and with the contact pad available in 3/8" to 3/4" diameters. They are available in many tooth pattern serrations pad styles.
A subset of the round head style is Accugrip, designed to fit chuck jaws. Accugrip is basically a round head type gripper but with housing and a lock screw component that allows the user to fit into a chuck jaw. The pad styles are flat and serrated and come only in inch sizes.
Lastly, the threaded body type of adjustable gripper, available in 1/2" to 1-1/2" and 25mm to 40mm lengths allows an internal hex for adjusting from backside. The body type is made from M2 high speed tool steel or carbide pad brazed into alloy steel body and comes in various tooth serrations.
