Bosch Rexroth linear motion

Electromechanical cylinders

Bosch Rexroth electromechanical cylinders (EMC series) convert the rotary motion of a servo motor into precise linear movement. The range primarily covers compensation couplings for cylinder series EMC32, EMC40, EMC50/63, and EMC100XC, which provide a misalignment-tolerant connection between the motor shaft and the cylinder drive. Couplings with M36x2 thread (EMC100XC) and their counterparts for EMC32, EMC40, and EMC50/63 allow installation even with slight angular deviations without affecting the cylinder's positioning accuracy.

How to choose Electromechanical cylinders

What matters when choosing: properties, comparison and typical applications.

Technical features

⚙ Compensation couplings EMC series - for cylinder sizes EMC32, EMC40, EMC50/63, EMC100XC
✓ M36x2 thread (EMC100XC) - couplings R349950900 and R349951100 for the largest cylinder size
⚡ Misalignment tolerance - compensates angular errors during motor coupling without affecting position
🛡 Direct motor connection - no gearbox required, high repetitive positioning accuracy
