The bearing of the joint heads is made by plain bearings with joints type X and XD limiting the maximum permissible speed to 300 rpm. The maximum diffraction angle per joint is 45°. The precision joints type X and XD are made of stainless steel and thus corrosion-resistant. Precision joints in an extendable version are […]

In case of overload the KTR-SI FRA overload couplings uncouple driving and driven side while protecting the drive train from damages. After eliminating the overload the KTR-SI FRA can automatically be re-engaged by reversing the direction of rotation for a short time. As a result, this version is optimally suitable for positions difficult to access. […]
