Electric Cylinder Accessories
Nook control panels are designed to match the motor when shipped from the factory. The control panels are acceptable to use in most industrial environments (including automotive). Functionality of the control panel can be customized to match any application. Spare parts are readily available.
- Matches the motor with no design time required
- Acceptable to use in most industrial environments (including automotive)
- Interconnects with other safety/control systems
Lubricant & Paint
Nook Industries lubricants are formulated specifically for each product and designed for peak performance in most application environments. NLGI #2 grease is formulated for both high and low temperature application.
Nook electric cylinders require lubrication to operate efficiently and with maximum life. Lubricants are available for both high and low temperature application. If operating conditions exceed 200°F or -20°F, contact Nook Industries for alternative lubricants.
The electric cylinders are shipped pre-greased unless otherwise specified. Before operating any unit, check the lubricant level. All jack housings are furnished with a grease fitting.
Electric Cylinders are painted with a unique enamel color blend. Available in 9 oz. aerosol cans in three different colors:
- Blue P-5100-25
- Red P-5100-26
- White P-5100-27
We can provide alternative colors and epoxy paints upon request, including specific mil spec paints.
Miter Gearbox & Handwheels
Electric cylinders may be used in multiple arrangements by connecting shafting, couplings, and gear boxes to simultaneously transmit power to the input shafts.
Miter Gearboxes are available in three sizes and straight bevel or spiral bevel gear sets.
A handwheel is a convenient solution for manually operating a jack when using electric cylinders in intermittent positioning applications. Handwheels are available in a range of diameters from 4 to 10 inches and can be adapted for use on electric cylinders.
Electric Cylinders used alone or in multiple arrangements require couplings to transmit power to the input shaft. Nook Industries provides jaw type and flex type couplings for use with electric cylinders.
ActionJac™ LinkJac™ Line Shafting is used to interconnect the input shafts of electric cylinders used in a multiple arrangement. The shafts transfer the torque from the motor to the cylinder or from cylinder to cylinder. LinkJac™ is available in either steel Line Shafting available in standard lengths up to 144", or in aluminum Tubular Shafting with bonded journals of stainless steel available in lengths up to 196". Custom end machining and other diameters are available. Contact Nook Industries for information.
Rotary Limit Switches
Every motorized electric cylinder must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached. The ActionJac™ rotary limit switch senses extension shaft rotation and provides switch contact closures that can be used to control motors.
The ActionJac™ rotary limit switch assembly is mounted to the extension shaft side of the electric cylinder opposite the input.
Compact Limit Switch (CLS)
Every motorized electric cylinder must be controlled so that power to the motor is turned off and the brake engaged before the limits of mechanical travel are reached. The ActionJac™ Compact Limit Switch (CLS) senses extension shaft rotation and provides switch contact closures that can be used to control motors.
Sensors, Encoders & Counters
The Nook Sensor System™ (NSS) is designed to meet the need for low cost position sensing on electric cylinders. It is highly accurate, with repeatability up to ± .004" (0.1mm). The patented design allows users to install and adjust sensors on a single electric cylinder and integrate easily with a motion control system. Since there is zero maintenance, the Nook Sensor System™ helps control electric cylinder systems in ways never before possible.
For precise position sensing at the input shaft, an ActionJac™ in-line encoder option may be factory installed between the motor and motor adapter or Right-Angle Reducer. This low cost option requires minimal space, leaving the extension shaft side of the electric cylinder free for clearance, for a rotary limit switch, or for coupling to another electric cylinder.
The in-line encoder's quadrature output design allows detection of both speed and direction of shaft rotation.
For precise position display, a range of digital position indicators are available for use with electric cylinders. These indicators measure the rotation of the input shaft and display a corresponding position in a counter window.
RA Reducers & Brake Motors
The High Efficiency Right-Angle Reducer is a compact, high quality worm gear reducer enclosed in an aluminum casted housing. The reducer mounts directly to the input side of the jack. Motors mount quill-style to a standard NEMA C-face. The High Efficiency Right-Angle Reducers are non-vented, oil filled, and maintenance free. They are rated at 85% or greater efficiency - allowing for a smaller drive and motor when compared with standard efficiency right-angle reducers.
ActionJac™ Worm Gear Screw jacks and Electric Cylinders can be supplied with industrial quality. They include a spring actuated, electrically released braking mechanism that holds a load when the power is off. In normal operation, power is applied and removed to the motor windings and brake release simultaneously.
Motors can either be supplied with the brake wired externally to accommodate speed controllers, or internally for simplicity of use.
Bellows boots are available for all sizes and configurations of electric cylinders. A boot protects the lifting shaft from contamination and helps retain lubricant to ensure long electric cylinder life.
