The choice between helical and spur gears in planetary gearboxes may seem straightforward. Go with helical gears if you want the gearbox to run as smoothly and quietly as possible. Choose spur gears when you need to maximize the gearbox’s torque density or working life … [Read more...]
Miniature Linear Bearings Offer Maximum Performance
In the semiconductor, medical, surgical, robotics and precision machinery industries, components must sometimes be sized to the smallest dimensions possible to meet demanding performance criteria. When bearing sizes range from 1 to 25mm, load capacity and maintenance can become more of an issue than … [Read more...]
What are dual-motion hybrid actuators and where do they excel?
Some motion applications need axes to deliver both linear and rotary motion. Conventional designs for such functionality are often complicated and bulky. What’s more, rotary motors put to linear motion often have output shafts that are inadequate for supporting heavy side loads. Download the … [Read more...]
Noise and vibration in leadscrew-driven motion designs and how to avoid them
Leadscrews — especially those with high-accuracy threads — can be a low-vibration alternative to other linear-motion options. That’s in part because of the consistent contact between their load-bearing mating subcomponents. Download the white paper from Ametek … [Read more...]
Considerations for adding Linear Guide Features to Industrial equipment
Bishop-Wisecarver understands the difficulties you may face when designing and building a machine. A properly selected product such as QuickTrak®, reduces design and installation costs by easily integrating into machine configurations and helping to eliminate or reduce manual processes resulting in … [Read more...]
Springs Perform Many Key Functions in Aerospace Applications
From jet engines to cargo doors, springs play a critical role in aerospace motion control applications. Read this FAQ to learn about the strength, material and durability considerations for designing springs that can withstand the extreme conditions inherent in the science of flight. … [Read more...]
Deliver the most efficient, precise performance
Ball screws are mechanical linear actuators that convert rotary movement into linear motion with little friction, which boosts efficiency. Due to this efficiency, ball screws are ideal for a variety of industrial and medical applications such as medical imaging devices, diagnostic and surgical … [Read more...]
Saving energy and service cost with electric linear systems
Today we are seeing a major shift from pneumatic linear actuators to electromechanical systems. This is because of high maintenance requirements of pneumatic and hydraulic systems which results in long machine downtimes and lost productivity. But can electrical linear systems truly fill in as a … [Read more...]
Do You Know the Basics of Thermal Expansion?
Motion systems with very long length capabilities like the LoPro® Linear Actuators from Bishop-Wisecarver may require careful evaluation. Thermal expansion is one of the problems that can plague your long motion system application, but it doesn’t have to be! Basics of Thermal Expansion is a … [Read more...]
The Long-Term Advantages of Linear Piston Free Pumps and Aerators
This paper examines the idea of design simplicity as it relates to compressors and vacuum pumps comparing and contrasting conventional design (i.e., motor-driven and diaphragm) with the linear motor free piston system design. … [Read more...]
