Product description and operating principleComparison to fluid mechanic actuators:

Electromechanical cylinder transforms rotary motion of a motor to linear displacement of the piston rod via a ball screw drive. Combination with a servo drive enables precise control of speed, position and force. (Fluid mechanics: pressure, flow or piston surface area with air, oil or water)

Comparison to a linear axis:

An EMC extends or retracts the piston rod freely in space. This changing actuator length opens up new possibilities for linear motion applications in addition to rodless linear axes.

Pressing , forming, joiningApplication possibilities

Swivel mechanisms

Unlike linear axes the EMC extends freely in space


5


Simple control and flexible positioning High accuracy and dynamics Energy efficient Machine set up does not allow fluid mechanics Space saving and simple integration to purely electromechanical

machine concepts Simple and quick commissioning

Drivers for electromechanics

EMC is an energy efficient and versatile alternative to pneumatic cylinders


6


Benefits of the EMC Hygienic design Effective sealing: Protection class IP65, sealed against external

contamination and lubrication leaks (optional) Easy to access one-point lubrication with an optional connection

to automatic lubrication system reduces downtime and costs Precision ball screw drive: High efficiency and performance Flexible and complete system provides optimal solution to

customers applications Ready-to-install solution: Simple engineering and quick assembly Freely programmable motion cycles with intelligent servo drive

systemFlexible & configurable: The EMC from Bosch Rexroth fits } Exactly

MotorMotor attachment

Housing

Front cover

Piston rod

Threaded bolt with hex nut Base

Structural design without mounting elements

The principle design has not changed from EMC Generation 1.



Structural design, standard cylinder Clean Design housing without T-slot

(switch mounting profile as optional accessory)

Countersunk fastening bolts (Clean Design)

Easily accessible lubrication point (can be connected to an automatic lubrication system)

Improved technical specifications Low radial forces allowed on the piston

rod Ball screw drive (BSA) with 2% preload ,

optional grease / oil lubrication or with preservative oil only (bearings and anti-rotation device are always lubricated)

New sizeEMC-100-XC-2 with BSA Ø50 All mounting elements with only a few

exceptions are suitable for Fmax

The 2nd generation EMC can be ordered with three different housing variants


10


Structural design with IP65 optionSpecial features:1. Paper seals between the

housing and front cover and base

2. Pressure compensation hole with hose connector in the housing to prevent the cylinder from drawing in contaminated air

3. Reinforced seals for the piston rod

4. Protection Class IP65 for all motor attachments

Structural design with IP65 +R optionsSpecial features:1. Aluminum seals between

the housing, front cover and base

2. Pressure compensation hole with stainless steel hose connector in the housing to prevent the cylinder from drawing in contaminated air

3. Stainless steel lubrication connector

4. Reinforced chemical resistant seals for the piston rod

5. No initial lubrication on the piston rod

6. Stainless steel plugs for bolts (available as accessory)

7. Protection Class IP65 for all motor attachments

Structural design based on parameter smax

smax= maximum stroke is the base of all length dimensionsLad = additional lengthLBC = total length of housing and front cover and baseLZS = Position of the retracted piston rod (at 0 mm stroke)

Calculation of EMC total length depends on smax


13


Dimensions

Dimension LBC is the same in first and second generation EMC‘s – cylinders with the same smax are interchangeable

Re-lurication of the screw drive system is required.For lubrication the ball screw nut must be positioned in the lubrication position.The location of the lubrication port can be defined in two different ways:S1 – distance from the base to the lubrication positionS2 – distance from the piston rod end to the front coverPositioning tolerance is ±2 mm The lubrication port is directly accessible and is located on the centerline of the cylinder.The EMC can be connected to an automatic lubrication system.Lubrication options:1. Initial lubrication with Dynalub 510 (NLGI 2)2. Initial lubrication Dynalub 520 (NLGI 00) for

automated lubrication systems3. Ball screw drive with only preserving oil –
