Specifications
The HOMIPNEU SR series provides hydraulic resistance to regulate linear feed motion. Used with an external drive, such as a pneumatic cylinder, it helps control the working stroke, while an internal spring returns the rod after the external force is removed.

Product Features
Hydraulic Control of Linear Feed
Hydraulic resistance helps regulate the movement of an externally driven mechanism. The SR series is intended for controlled feed applications where the working motion needs to be steady.
Spring Return
The internal spring returns the rod after the applied force is removed, preparing the unit for the next operating cycle.
Sealed Hydraulic Construction
The sealed structure helps retain hydraulic oil and limit contaminant entry. This supports consistent operation in suitable industrial installations.
Hydraulic Oil Selected for Viscosity Stability
The published product description specifies hydraulic oil with stable viscosity characteristics during temperature changes. Actual feed performance should be checked under the application’s operating conditions.
Five Stroke Options
Maximum strokes of 15, 30, 60, 80 and 100 mm allow selection around the required controlled travel and available mounting space.
Compact Integration
The linear body format supports installation alongside pneumatic cylinders, feed slides and automated mechanisms.
Applications
Pneumatic Cylinder Feed Control
Works with suitable pneumatic cylinder mechanisms to regulate the working feed stroke. The cylinder supplies the driving force, while the hydraulic controller provides resistance.
Drilling and Tapping Equipment
Can be evaluated for controlling tool approach or working feed where a steady linear movement is required.
Grinding Machines
Supports controlled movement of suitable feed mechanisms, subject to the required force, travel and operating frequency.
Cutting Equipment
Can be incorporated into linear feed assemblies where hydraulic resistance is needed to regulate the cutting advance.
Automated Handling Mechanisms
Suitable for evaluating controlled approach movements in handling and assembly equipment.
Special-Purpose Machinery
Provides a hydraulic feed-control option for dedicated machines requiring a controlled working stroke followed by spring return.
Why Choose HOMIPNEU
Stroke Options for Different Mechanisms

Published Dimensions for Integration
The model table and drawing help engineers review overall length, working stroke and installation clearance before ordering.
Application-Based Selection Support
Provide the driving force, desired feed speed, working stroke, cycle rate and mounting arrangement so the proposed model can be reviewed against the application.
Related Pneumatic Components
HOMIPNEU also supplies pneumatic cylinders, valves, fittings and tubing for the associated drive and air-control system.
FAQ
What is an SR hydraulic speed controller?
It is a hydraulic device that provides resistance to regulate linear feed motion. An external mechanism drives the working stroke, and an internal spring returns the rod after the applied force is removed.
Is it a gear speed reducer?
No. The SR series controls linear motion through hydraulic resistance. It does not use gears to reduce rotational speed or increase output torque.
How does it work with a pneumatic cylinder?
The pneumatic cylinder supplies the driving force. When the mechanism acts against the hydraulic controller, the controller provides resistance to help regulate the feed movement.
Does it drive the machine mechanism itself?
No. It requires an external driving force. The internal spring provides rod return rather than the machine’s powered working stroke.
What is the difference between this product and a hydraulic shock absorber?
A hydraulic feed controller is intended to regulate motion over a working stroke. A shock absorber is primarily selected to absorb impact energy and decelerate a moving load. Selection criteria differ between the two applications.
What strokes are available?
The listed maximum strokes are 15, 30, 60, 80 and 100 mm, corresponding to SR15, SR30, SR60, SR80 and SR100.
What does the 350 kgf maximum load mean?
It is the published force rating, equivalent to approximately 3.43 kN. It does not mean the unit can stop or control any moving object weighing 350 kg.
What is the operating temperature range?
The published operating temperature range is 0–70°C.
What feed-speed range is available?
The current page does not publish a numerical feed-speed range. Provide the desired speed, applied force and cycle conditions for confirmation before ordering.
