Linear-actuator application example: New angle on wheelchair vehicle accessibility
Kneeling systems have become widespread on custom wheelchair-accessible vehicles from BraunAbility and other accessible-vehicle converters. Here linear actuators lower vehicles’ rear suspension to reduce the incline angle of wheelchair ramps for easier access. Because the actuators typically mount under the vehicle chassis, they must be rugged. “Our vehicles typically kneel 2.5 to 3 in. We […]
High-speed linear actuators: What qualifies them as high speed?
Like many terms used in the linear motion industry, such as “heavy duty,” “miniature,” and “corrosion-resistant,” to name a few, there is no industry standard that specifies what constitutes a “high-speed” linear actuator. Nevertheless, there are some general guidelines that manufacturers follow when classifying and marketing their actuators as high speed. These guidelines are typically […]

What is a 12 volt linear actuator?
Linear actuators are typically characterized by their drive mechanism – belt drive, ball or lead screw drive, pneumatic drive, etc. But it’s not unusual for rod style electric actuators to be classified by the input voltage – commonly 12 or 24 volts – of their integrated motors. These actuators provide thrust force, much like a […]

As part of its cyber dynamic line product series, WITTENSTEIN cyber motor has launched a new series of linear actuators designed with an integrated ball screw […]
Linear actuator designs for vertical lifts: How to size a jack?
Linear actuator designs for vertical lifts often take the form of worm screw jacks. There are several criteria by which a worm screw jack can be sized properly — six primary factors, to be exact. First is the basic tonnage rating of the jack. This is simply the overall capacity that a jack can handle […]
What are the six basic parts of a worm-gear jack for vertical motion applications?
Screw jacks are indispensable linear-motion designs for lifts and other vertical-motion applications. They consist of six main components. First there is the housing. This contains all of the internal jack components. Second is the worm shaft – this is an input to the jack and typically where a motor handwheel is attached. The third jack […]
Vertical linear motion: Hoists to lifts to AS/RS reach new heights
New technologies boost the reliability and efficiency of vertical motion designs (including an array of lifts and hoists) for setups of various sizes. In the feature, we get input from one industry expert on the subject and then outline five key parameters that dictate what makes linear actuators suitable for lifting. Mounting orientation — especially […]
