Torqmaster Advantages
Constant Torque
Regardless of shaft angular position, predictable, positive, constant, mechanically balanced torque is produced in either direction. There is an absolute linear relationship to pressure and output torque making the sizing and application simple to specify.
Balanced Bearings
Twin rack construction ensures the pinion shaft bearing is balanced by each rack under pressure.
Cushioning
Cushioning is available as an optional option to slow down operation at the end of stroke. Normally effective over the last 10 to 15 degrees of rotation in each direction.
End Stops
End stops are available as an option to trim the rotation. Each adjuster can reduce the total rotation by ten degrees. This assists in trimming the applications end position.
Space Envelope
Compact design when compared to other rotary actuators on the market.
Variable Torque
Torque can be varied by adjusting the hydraulic pressure, up to a max of 210Bar working pressure.
Variable Speed
Speed can be varied by adjusting the hydraulic flow rate.
Efficiency
Extremely volumetric efficient. Mechanical losses within the actuator have already been accounted for in the published figures.
SWP Torqmaster
Special Variants
Spring return system
Ensuring the actuator always returns to its open or closed position.
Mechanical override
Allowing the actuator to operate in the event of hydraulic failure.
Position indication
Indicating movement in degrees, or end stop position.
Fail safe spring pack
Safety feature, ensuring pinion returns to its desired position.
Non-standard materials
Designed to suit various environmental conditions.
Special paint options
Subsea / top side / industrial / water based / enamel or just undercoat.
Drive Style
Single and double output shafts with keyways are standard.
Output Shaft Datum
When Torqmaster actuators are provided with a keyway, this will be at the twelve o’clock position at the mid-rotation point.
Hollow Pinion Shafts
Hollow Pinion Shafts can be offered where mating space is at a premium. This removes the need for a drive coupling but should not be used at pressures above 100 BAR (1500psi).
Mounting Supports
Mounting Supports the actuator to its intended position, which will vary dependent on the application. Various configurations can be offered which are typically X4 blind tapped holes located into the mounting face of the actuator.
Port Position
The standard port position will always be supplied unless the alternative is specified by quoting.
Seal Options
Various seals options are available to suit your specific requirements, including cycle, high temperature and subsea variants.
Paint Finish
Impressive in-house paint facilities, including Alkaline hot wash for degreasing, shot blast preparation for superior adhesion and a modern paint booth for a quality finish.
Size & Economy
SWP Torqmaster is more compact than a hydraulic cylinder with crank arm, more reliable than an electric motor and gearbox. Rated for continuous industrial duty, it is ideal for continuous automation and inertial loads. Please check with our applications department for suitability of your selection.
Material Options
SWP Torqmaster Actuators can be made from various materials to suit customer specific environmental conditions. Standard variant is typically carbon steel, however we able to supply actuators in the following alternative materials:
• NAB
• Copper Nickel
• Super Duplex
• Monel
• Aluminium
Racks, pinions and seals are specified to suit the application and technical requirements.
