Custom Hydraulic Cylinder Engineering for OEM Projects
Working on a new fitness machine or upgrading an existing actuator? DALLAST engineers collaborate directly with OEM design teams to tailor damping curves, stroke lengths, and mounting interfaces.
To speed up technical evaluation, please include the following in your enquiry:
Equipment type & biomechanics:The machine type (e.g., squat, rower, rehab) and how the cylinder integrates into the lever arm.
Target resistance & adjustment:*Force requirements (in Newtons) across settings during extension and compression.
Return behavior:Whether free return, damped return, or automatic self-return is required.
Envelope dimensions:Stroke length, retracted/extended pin-to-pin center distances, and maximum allowable outer diameter.
Mounting interface:End-fitting style (eyelet, clevis, spherical bearing), pin diameter, and pivot width.
Duty cycle & environment:Expected stroke speed, daily cycle frequency, and indoor vs. outdoor installation.
Replacing an existing cylinder? Send us the current part number, physical dimensions, or a sample unit, along with any performance improvements you want to achieve.
Discuss Your Custom Project with an Engineer
Built for Commercial Gym and Outdoor Fitness Equipment
Indoor Commercial & Rehab Equipment
For indoor selectorized or hydraulic-resistance machines, our focus is on smooth, noise-free operation, zero oil leakage, and consistent force curves across thousands of daily repetitions. Specify your target adjustment tactile feel, space envelope, and cycle life requirements.
Outdoor Fitness & Park Equipment
Outdoor installations face rain, high humidity, UV exposure, dust, and wide seasonal temperature swings. Tell us about your environmental standards-we can configure your cylinders with upgraded rod surface treatments (such as hard chrome or salt-spray tested coatings), heavy-duty wiper seals, and low-temperature hydraulic fluids to prevent performance drift.
FAQ
Q: How do I choose between tension damping and bidirectional damping?
A: It depends on the exercise mechanics. Choose tension damping if the user works against resistance in one direction (extension) and needs a light or assisted return stroke. Choose bidirectional damping if the machine requires concentric work in both pushing and pulling movements (such as combined chest press/row stations).
Q: Do all adjustable fitness cylinders return to their starting position automatically?
A: No. Automatic return requires an internal spring or gas-charged mechanism and is offered as a dedicated configuration within selected series. If your machine linkage does not return by gravity or user action, specify **automatic return** along with your required retraction force and speed.
Q: Can you customize the stroke length, pin-to-pin distance, or end fittings?
A: Yes. As an OEM manufacturer, we regularly modify stroke lengths, retracted dimensions, mounting eyelets/clevises, and damping valves to fit proprietary machine frames. Share your envelope drawing and target volume so we can confirm feasibility for your chosen series.
