in the linear unit from the exterior. This is accomplished using sturdy seals that have been tried and tested in hydraulic systems. The result is that no seals are needed on the individual inner components.
The oil bath has a positive effect on the service life of spindle nuts, bearings and guides. It leads to less friction and therefore less heating of the components. The lubricant dissipates heat from the components inside the motor to the surface of the housing. In addition, start-up from a standstill is easier, without a slip-stick effect. The CMS63S electric cylinder does not have any vent holes, is hermetically sealed and is rated IP65, providing a high degree of protection. The piston rod seal is permanently leakage-free. Thus, the drive is especially suitable when hygienic requirements or requirements for protection against moisture and dust are high, as well as in rough operating conditions. In combination with the boundary hardened, chrome-plated piston rod, which also has an integrated locking lug (torque arm), the electric cylinder achieves the same features as the hydraulic cylinder, which has been tried and tested millions of times, in a wide range of applications.
Users can opt for an absolute encoder (a Hiperface encoder) instead of the standard resolver feedback, and can also choose from among differing ways of installing the cylinder. Further options include having a 24 V forced cooling fan attached as well as having the electric cylinder supplied as a brake servomotor with a 24 V holding brake.
If the application requires that the CMS63S or M be operated at the thermal load limit, or if the load limit needs to be increased, the motor can be supplied with water cooling. The standard version of size 63 is already equipped with the necessary connection openings.
