3 StructureFunctional description


3 Structure3.1 Functional description

A CMP50/63/71 servomotor is used as the drive for the modular unit. Depending onthe design, the servomotor is mounted to the modular unit using different couplingadapters (/ACA, /ACH). The use of a third-party motor is also possible.The threaded spindle with guide is located in the modular unit. The installed servomo-tor turns the threaded spindle via a coupling while the nut is fixed. The nut is routed inan aluminum extruded housing via T-slot nuts. The nut and piston rod are connectedto each other. The piston rod has a smooth, high-quality corrosion-proof surface and issealed with a sealing system. The joint head is connected to the piston rod. An oil bathlubrication system supplies the bearing points, threaded spindle and seals with lubri-cant.All CMSM.. modular electric cylinders are filled with lubricant (optionally with foodgrade lubricant) at the factory in mounting position M0 (universal).

3.2 Combination optionsThe CMSM.. modular electric cylinder is a separate modular unit of the standardCMS.. electric cylinders. They can be combined with the servomotors of the CMP..series via the following adapters. The use of a third-party motor is also possible.• ACA for motors with key• ACH for motors without keyThe following figure shows the combination options of CMSM.. modular electric cylin-ders with adapter and CMP.. series servomotors:

4.2.4 Mechanical stroke limiting

INFORMATIONThe customer must limit the stroke of the CMSM.. modular electric cylinder by provid-ing for appropriate measures in the extended and retracted position, e.g. by usinglimit stops, cushioning or shock absorbers.

The maximum permitted feed force of the CMSM.. modular electric cylinder must notbe exceeded. That is why the mechanical limiting elements built-in by the customermust be able to absorb the reactive forces and kinetic energy that is created when theend position stops are reached. Soft, damping elements are necessary. Their purposeis to absorb the energy and then limit the end position mechanically. As a rule, youshould use cushioning or shock absorbers that are dimensioned accordingly.

INFORMATIONThe rated stroke length (HCMS), e.g. stroke 200 mm, is only available in limited formfor the customer application because safety distances (S) to the limit stops restrictthe effective stroke (Heff).

6 Inspection/maintenanceLiquid cooling


6.1 Liquid coolingLiquid cooling can significantly increase the thermal capacity of the drive. The data forliquid cooling in the power diagrams for the thermal limit torque are based on the fol-lowing parameters:

• Temperature of cooling liquid inlet 25 °C

• Temperature increase at cooling liquid outlet about 5 °C• Flow rate: 2 l/min for CMSMB50/63• Flow rate: 4 l/min for CMSMB71Higher flow rates increase the cooling effect only slightly.Cooling liquid requirements:

• Max. operating pressure 2 bar

• demineralized and desalinated• No foreign objects and sediments• Frost protection, if necessaryThe components through which the cooling liquid flows are corrosion-protected. Thecooling liquid must not contain any chemically aggressive additives, contactSEW‑EURODRIVE if necessary.

6.1.1 Liquid cooling at CMSMB50 (in preparation)The CMSMB50 can optionally be equipped with a connection option for liquid cooling.Inlet and outlet connection for cooling liquid can be exchanged.A cooling liquid connection is provided on the A-side motor flange.

6.1.2 Liquid cooling at CMSMB63/71The CMSMB63/71 is equipped with a liquid cooling connection option as standard.Inlet and outlet connection for cooling liquid can be exchanged.

6Inspection/maintenanceOil bath lubrication for CMSMB50 – 71


6.2 Oil bath lubrication for CMSMB50 – 71The CMSMB50 – 71 modular electric cylinders are equipped with an oil bath lubrica-tion with little maintenance requirements. The only required maintenance measure is aregular visual check for leaks. The oil need not be changed in usual applications.An oil change might make sense for applications with the following higher require-ments:

• Travel cycles with a cyclic duration factor > 60% and an operational performance of> 1 km/hour.

• Working strokes < 10 mm with stroke frequencies > 5 Hz• Expected service life > 10 000 hours of nominal operationPlease contact SEW‑EURODRIVE if necessary.As standard, CMSMB50 – 71 modular electric cylinders are filled with the lubricantMobil SHC630 at the plant. This lubricant is used for recirculating ball screws andplanetary roller screws.As an alternative, you can order CMSMB50 – 71 with food-grade Castrol OPTIMOLOPTILEB GT from SEW‑EURODRIVE.

6.2.1 Maintenance work oil bath lubrication

INFORMATIONThe oil screw plug of the electric cylinder must not be opened.

The sealing system and the components have been developed and tested to comple-ment each other. Observe the following notes in order not to reduce the service life:

• Do not paint the piston rod

• Do not expose the piston rod to potential damage resulting from hard components

• Protect the piston rod from clinging foreign substances (e.g. cleaning agent, sweat)• Make sure that the joints are free to move• Visually check for any leakages regularly, at least every other week

Replacement interval of wearing parts

The drive reaches the end of its service life after 10 000 hours of nominal operation. Ageneral overhaul and refit of the drive is not recommended.
