10k to 300k in.lbf (1,000 to 30k N.m)

Torsion Testers

    For maximum versatility and  capability, Tinius Olsen offers a full range of torsion testing machines in capacities from 10,000 to 300,000 in.lbf or (1,000 to 30,000 N.m). Higher capacity and other longer length models are available upon request.    

    Our 10,000 in.lbf (1,000 N.m) torsion tester is bench mountable and the moveable section slides on a guide rail. All other models are floor based and are furnished with heavy duty slotted steel bed rails that are normally embedded in, or secured to, a concrete foundation to assure maximum rigidity and accessibility. The moveable section on these higher capacity machines is mounted on four rollers that glide along these slotted rails and allow rapid positioning. Additionally, these rollers allow the moveable unit to compensate for any changes in specimen length during loading. The standard maximum distance between chucks is 7 ft ( approx 2.1 m); however, other lengths can be provided.
