Do you have a mechanical design project in the works? If yes, you'll likely need to consider a linear motion control solution. While various lead screws are available for use in mechanical design, Acme screws have characteristics that separate them from competing hardware, like roller screws and ball screws. The engineering advantages of precision acme lead screws may be just what you need to add value to your design.

Acme lead screw assemblies are used to convert rotary motion into linear motion by turning the screw or the nut. One of the most popular types of lead screws uses the Acme thread form which typically has an included thread angle of 29°.

Rail car door systems are historically one of the most complex, inconsistently performing, and potentially unsafe components in rail transit systems worldwide. Yet safety is of utmost importance when human lives are at stake in accidents that may result in injury and/or death.

Linear motion by its very definition is motion along a line or linear path. Linear motion solutions take advantage of this movement to accomplish many tasks. However, selecting the right screw is not always easy albeit it necessary to get the job done effectively and efficiently.

When it comes to actuators for motion control applications, there are several types to choose from. These include pneumatic, hydraulic, electric, or electro-mechanical.

Comfortable and cost-effective airline seating is in the cross hairs of major aircraft manufacturers around the globe.

Engineers can choose from various technologies such as electrical (electro-mechanical), hydraulic or pneumatic technologies when selecting linear actuators for motion control applications. In nearly all cases, an electrical actuator will prove to be the better choice due to a unique combination of characteristics.

The only thing constant is change, especially for medical device manufacturers, which face ongoing pressures to introduce new products or highly modified versions of existing devices at a faster pace than any other industry.

Until the recent emergence of new heating, ventilation, and air conditioning (HVAC) demands for green buildings, the HVAC industry historically developed systems and supporting ductwork that were designed for overcapacity.

Globally, rail car systems build-out is projected for strong growth well into the foreseeable future. The design of rail car components has seen similar steady movement.
