Single holding - Import export

In particular applications, it can be necessary to hold high axial forces and torque at the same time. For pneumatic operation, our Locking Unit series KFPD meets this demand. Depending in the size, forces / torques of 12 kN / 120 Nm or 30 kN / 500 Nm can be held securely. The “normal” SITEMA Locking Units KFH are already able to hold smaller torque. Example: 280 Nm with, at the same time, an axial holding force of 100 kN on rod diameter 56. In case higher torque needs to be held, SITEMA’s special design series KFHD can help. With this design, it is possible to hold torque with a factor of 10 higher compared to the standard KFH unit. Example: 2800 Nm with, at the same time, an axial holding force of 100 kN on rod diameter 56. Whether the operation is pneumatic or hydraulic, the application is limited to static holding. The KFPD and KFHD can prevent a rotation from starting, but are not suitable to brake rotating masses.

Several bunched single wires or bundles made from Cu-ETP1 and Cu-OF1 in bare, tin-plated, nickel-plated or silver-plated, soft annealed. Single-wire diameter ranging from Ø 0.05 mm to Ø 0.51 mm, left-hand lay or right-hand lay. Cross-section ranging from 0.005 mm² to 630 mm². Those single wires do not hold a fixed position inside the strand. Their position relative to one another undergoes a permanent change along the entire length of the bunch. The construction of a bunch is derived from the cross-section required, which leads to the electrical conductor featuring a certain resistance level. Different cross-sections with the same resistance value can be generated by applying single wires of varying sizes. Owing to their good efficiency our bunched single wires are versatile in a multitude of applications in cables and conductors.
