Creating a Power Jacks motorized actuator system requires a range of components, all of which have been selected to offer the best possible performance with Power Jacks’ range of screw jacks, linear actuators, and gearboxes.
Choose from a variety of couplings, driveshafts, motors, plummer blocks, hand wheels, limit switches and encoders to build the perfect solution for your situation.
Power Jacks has electric motors for all applications whether AC or DC motors are required. Motor brakes—spring applied electrically released units—provide the fail safe operating characteristics such that on interruption, or failure of the power supply, the brake will engage and arrest the load. All Power Jacks electric motors offer:
Power Jacks offers a wide range of reduction gearboxes for actuator system building whether just a single motorized actuator or several actuators mechanically linked.
While standard gearboxes are available as motorized units, gearboxes without motors are also available. The most popular types of gearboxes are Helical Worm, In-line Helical, and Parallel Shaft gearboxes. Other types are available upon request. Key features include:
Our 4 standard spider type jaw coupling with it's curved jaw design has no need for lubrication, making it a good low maintenance component. In a rugged aluminum and iron housing the coupling delivers smooth and silent operation in temperatures of -40° to +90°.
There are three standard drive shaft sizes offered by Power Jacks with ends machined to suit actuator system couplings however drive shafts can be supplied to customer sizes with specific end designs.
Plummer blocks are to DIN736 with anti-friction bearings, tapered bores, and adaptor sleeve. The housings are made of cast iron and are sealed with felt strips on both sides. The housings are designed to allow floating or located bearings.
Hand Wheels are made from polished aluminum casting and rotating handle and are Bored and keyed to BS4235 Part 1. Other types of hand wheels are available upon request.
Our range of motion control devices allows you to safe guard the operation of you actuator system and ensures it operates within the specified parameters. Choose from rotary, proximity, or mechanical components. Most are ideally suited to screw jack or linear actuator mounting. Power Jacks series geared cam limit switches are ideal for use as:
And allow integration of other feedback devices such as potentiometers and encoders inside their compact housing.
