ROTARY ACTUATORS We will design any size of Semi-Rotary Actuator to meet your exact requirements in terms of torque, pressure and rotation. The design is based on a machined rack and pinion configuration within a central housing, with cylinders to both sides of the housing providing the motive power. For large torques a double rack would be incorporated. For low torques the cylinders can be integral in the housing. TORQUE From 100 Nm to 600,000 Nm Rotation Any angle of rotation can be supplied but it is not normally practical to exceed 360°. Pressure Our normal design pressure would be 160 Barg. This provides for a good torque / size ratio, but still allows for high factors of safety on gear tooth loading. Design for higher or lower operation pressures can be supplied on request. Drive Interface The most standard would be a male shaft, with either a machined key way, or plain for use with a torque coupling such as a ring feeder. Hollow shafts with internal key ways are also available. Other Features The following can be incorporated into the design: – Adjustable Cushioning – End Stops – Position Indicators – Load control Valving ROTARY DISTRIBUTORS We will design and manufacture any requirement for special Rotary Distributor: 2 way to 16 way or above, For flows up to 450 Litre/Min, Pressures up to 400 Barg, For a combination of fluids, Speeds from 1 Rev/Min to 1000 Rev/Min. Applications – For use with Steel Works Rotary Mandrel Cylinder – For the hydraulic supply for mobile equipment with a slew function such as cranes or 360° machines. – Any special machine requiring fluid supply but with a rotating function. Design Choice of material and design would depend on each individual application. The following criteria would be considered: – Flow required – Rotation speed – Operating medium – Positive seals or clearance – Common or individual drain chambers. – Roller or plain bearings – Plating or surface treatment to Rotor and Stator Spa Fields Industrial Estate New Street Slaithwaite, Huddersfield West Yorkshire HD7 5BB United Kingdom Tel: +44 (0)1484 845740 Home About Quality Assurance Technical Downloads Contact Privacy Policy © Copyright 2021 Hystat | UK Registered 01244978 | Site by DCA
