VC25EUFT

For precision adjustment of feed rates

Adjustable
Compression force 30 N to 3,500 N
Stroke 15 mm to 125 mm

Precise adjustment for any type of application: The VC model of hydraulic feed controls is ideally suited for the precise tuning of constant feed rates. The thread of the outer body of this closed hydraulic element allows simple assembly. Designs with a smooth body can also be supplied.
As the hydraulic oil is forced out through the throttle opening, a constant feed rate is achieved on the stroke, which also avoids the stick-slip effect. In the models up to 55 mm stroke, the tried and tested rolling diaphragm, known from ACE shock absorbers, serves as a dynamic seal, as volume compensation of the piston rod and as a reset element.

The VC model of precision hydraulic feed controls is used in automotive and industrial applications as well as in automation and machine building and electronics industries.

Technical data

Compression force 30 N to 3,500 N

Stroke 15 mm to 125 mm

Piston rod diameter Ø 8 mm

Feed rate/Compression force Min. 0.013 m/min. at 400 N; Max. 38 m/min. at 3,500 N

Impact velocity range At speeds of 0.3 m/s the maximum allowed energy is approx. 1 Nm for units up to 55 mm stroke and approx. 2 Nm for units 75 mm to 125 mm stroke. Where higher energies occur use a shock absorber for the initial impact. Avoid high impact velocities.

Adjustment Infinitely adjustable

Positive stop External positive stops 1 mm to 1.5 mm before the end of stroke provided by the customer.

Damping medium Oil, temperature stable

Material Outer body: Black anodized aluminium; Piston rod: Hard chrome plated steel; Accessories: Steel with black oxide finish or nitride hardened

Mounting In any position

Operating temperature range 0 °C to 60 °C

Application field Handling modules, Linear slides, Automatic machinery, Conveyor equipment , Absorption control

Note

Nylon button PP600 can be fitted onto piston rod. Unit may be mounted in any position.

Safety information

Do not rotate piston rod, if excessive rotation force is applied rolling seal may rupture. External materials in the surrounding area can attack the seal components and lead to a shorter service life. Please contact ACE for appropriate solution suggestions.

On request

Special oil and other special options available on request.

Application Examples

VC25 handbike wheelchairs
VC25 handbike wheelchairs
The specially-designed handbike wheelchairs experience problems on bends as soon as roads are wet from rain. In order to make speed achievable on ice and not just when travelling in straight lines, a Dutchman developed a special construction. By using gas springs he was able to achieve speeds of 14 km/h on bends. With a gas-filled feed control this speed increased by 50 percent. This is made ...
