The onboard SKF actuator lifetime monitoring system continuously tracks actuator service-life status while in operation and signals when the actuator needs to be replaced. The system displays remaining service life via a simple LED color code display, using specific calculations. Green indicates more than 10% service life and orange indicates that only 10% remains. When […]

Roller Screw Jack Actuators
Roller screw jack actuators use a roller screw and nut ring gear assembly supported by two bearings. A worm gear in a stationary housing drives the actuators. The configuration distributes compression loads evenly for best handling of heavy loads in one direction. Multiple contact points in the roller screw design maximize load-carrying capacity. SKF Linear […]
Actuator Extends Nozzle’s Reach Into Dangerous Places
Leslie M. MorganHelac Corp. Firefighters have one of the most dangerous and demanding jobs in the public’s eye. They are called upon to face complex fires or natural disasters to save lives or property. Innovative technology to help protect people and property is in high demand from firefighting forces around the world. This urgent demand […]
Roller Screws for Linear Actuation
Roller screws for linear actuation can sustain static loads to 1,000 tons and dynamic loads to 200 tons, depending on type. The screws incorporate fine-lead threads, as small as 1 mm. Their robust nut can withstand shock loads; their timing mechanism is reliable at high acceleration; and a long lead and symmetrical nut design permits […]
Rodless Band Cylinder
The MX Rodless Band Cylinder has a modular body for lean manufacturing. It also comes in three different bearing designs to meet a variety of application needs. The Profiled Rail design’s THK Caged Ball technology reduces friction and extends actuator life. The Solid bearing design reduces stress concentration, and the Internal bearing design is permanently […]
No More Hoses and Valves
Electric actuators are quickly replacing hydraulic cylinders in mobile off-highway vehicles. They eliminate bulky hydraulic pumps, cumbersome hoses and valves, and minimize environmental damage from unavoidable fluid leaks. Electric actuators also increase operator safety and reduce fatigue with simple, easy-to-use controls. They can push and pull heavy loads and do not depend on ancillary brakes, […]
Metric Linear Actuators from J.W. Winco
Metric Linear Actuators with two separate threaded shafts have guide tubes of chrome plated precision steel, with metal follower nuts and plastic end caps. The tubes are also available in stainless steel. Tubes come in a variety of diameters, and travel lengths to 1,150 mm. The actuators may be ordered with one shaft right hand […]
Exlar Extrak™ Rodless Actuators
Chanhassen, MN – The Extrak™ RM and LM Series rodless actuators offer Exlar’s proven roller screw technology or high speed belt drives. With the roller screw driven versions, Exlar claims higher thrust loads and longer life than ball screw driven rodless actuators. The RM and LM Series offers the choice of motor brand and type […]
High Speed High Force Actuator
High speed LINAK introduces a high speed electric actuator. This speedy actuator, built on the LINAK LA36 actuator platform with a speed of up to 6.3 in/second (160 mm/sec) without a load and a maximum force of 112 lbs (500 N), is a revolutionary addition to the LINAK product range. High force In September, LINAK […]
Dura-Bar Revamps & Expands Website
Dura-Bar — North America’s only producer of continuous cast iron bar stock — recently completed a major revamp of its website, adding a number of on-line tools, and information. The company’s new website is designed to help identify the material advantages and cost savings offered by Dura-Bar as a substitute for steel, castings, and/or aluminum. […]
