YLK Servo Electric Cylinders · By Mounting Style
The same cylinder type can be supplied with different mounting styles to suit the installation space: inline versions keep the motor and screw on one axis for a compact body, while reverse-parallel versions use a timing-belt drive for a shorter overall length — front, side and rear flanges, guide rods, clevises and Y-joints are available.

PARAMETERS & NAMING RULES
YLK Selection Data & Model Naming Rules
From model naming rules to cylinder type, screw lead, mounting style and motor power, this section explains how to read a YLK servo electric cylinder model and select the right one. For more screw lead, motor power and thrust/speed combinations, please contact us for the full catalog.
Model naming rules
From left to right: series → cylinder type → stroke → screw lead → mounting style → motor interface → motor power.
YLK94-200C10ZKB-X10-M1.5
Series YLK
Series code for Youlke YLK servo electric cylinders — modular linear actuators that integrate a servo motor with a precision screw.
Cylinder type 94
Body size code, commonly 40, 50, 60, 80, 94, 110, 134, 142 and 175. Larger types handle higher thrust and longer strokes.
Stroke 200
Effective stroke in millimetres. For example, 100 means a 100mm stroke and 200 means 200mm, chosen from your mechanism travel.
Screw lead C10
Screw lead codes: C02 = 2mm, C05 = 5mm, C10 = 10mm, C20 = 20mm, C32 = 32mm. A larger lead gives higher speed, a smaller lead gives higher thrust.
Mounting style ZKB
The first letter Z means inline and S means reverse-parallel. The following letters indicate front flange, side flange, rear flange, guide rod or clevis — see the code table below.
Motor interface X10
Motor flange and interface size code, such as X1, X10, X12 or X16, used to match servo or stepper motors with the corresponding flange size.
Motor power M1.5
Motor power codes: M0.1 = 100W, M0.4 = 400W, M0.75 = 750W, M1.5 = 1.5kW and M3.0 = 3kW, selected according to speed and thrust needs.
Note: the above is the general naming rule for standard YLK models. Special strokes, special mounting, protection levels and sensor configurations are subject to technical confirmation and the final contract.
Drive and mounting style codes
Codes starting with Z are inline (motor and screw on the same axis); codes starting with S are reverse-parallel.
| Code | Drive Type | Mounting / Rod End | Notes |
|---|---|---|---|
| ZKA | Inline | Front flange | Compact, front mounting |
| ZKB | Inline | Side flange | Side mounting in tight spaces |
| ZKD | Inline | Guide rod | Guided, resists offset load and torque |
| SKA | Reverse-parallel | Front flange | Short overall length for long strokes |
| SKB | Reverse-parallel | Side flange | Reverse-parallel with side mounting |
| SKH | Reverse-parallel | Rear flange | Motor at rear, rear mounting |
| SKD | Reverse-parallel | Guide rod | Reverse-parallel with guide, resists offset load |
| SQC | Reverse-parallel | Front clevis, rear single ear | Pivot mounting with angular freedom |
| SNA | Reverse-parallel | Front flange, internal thread | Internal thread rod end |
