Electromechanical rodless linear actuators can offer better load handling in smaller spaces than rod-style actuators, but realizing those benefits requires careful attention at the specification level. Whether you are replacing a failed actuator, looking for better performance or building a new application from the ground up, success depends on how precisely you specify application requirements.

Automated production of large objects such as auto body prototypes, boat hulls and surfboards traditionally requires computerized numerical control (CNC) systems costing nearly a million dollars. Thomson Cuts Costs and Production Time for Autoscale Inc.
Clutches and Brakes take center stage in the April 2017 edition of Product News.
Iâ™m building a custom gearbox with 7075 T-6 spur gears, and Iâ™m concerned that aluminum flakes will enter the races on the roller bearings (SKF 2307) and cause premature failure. So my question is â” should I place an oil seal on the shaft first to protect the bearing â” or is this an unfounded concern and I should mount the seal in the typical manner outside the bearing? Or both? Or go with a sealed bearing? Iâ™m confused and could use your expertise, please.
Tapered roller bearings can be set at initial machine assembly to any desired axial or radial clearance. This unique feature enables a designer to control bearings to meet anticipated application operating conditions, and thereby provide optimum bearing and system performance.
Believe me when I tell you that â” as a domestic automotive engineer â” I bleed U.S. manufacturing. I have never lived more than 50 miles from Detroit,
A reader asks: I have heard that new axles no longer need a break-in period. True or false?
Many of us have been there; the bearings had the correct preload. You know it, you were there, and you personally saw the measurements. Now, the testing is done and the preload is gone. Not a little gone, not sort of gone - gone, gone. Finger pointing ensues. Suppliers are dragged in by their wrinkly Polo collars. You know the drill. Losing preload in a tapered roller bearing (TRB) system over the life of your application can be a troublesome problem, particularly for gear sets that are prone to noise or severe applications that rely on a very rigid and stable system.
What are the best methods to adjust tapered roller bearings?
This article summarizes some common hurdles, issues and questions encountered by the newer and casual users of tapered roller bearings.
This paper is intended to enlarge the application range of radial cylindrical roller bearings by means of a more precise determination of thrust load capacity and more cost-effective design.
A reader asks for clarification on last issue's Ask the Expert column about ball screw sizing.
The ball screw drive is an assembly that converts rotary motion to linear motion and vice versa. The ball screw drive consists of a ball screw and a ball nut with recirculating ball bearings...
At a Midwestern producer of tubular steel products, measures taken to counteract the effects of impact on a quench tank roll made it difficult to remove and replace the conventional pillow block bearings that support the rollâ™s shaft.

This special product news section takes a look at the latest in motion control products.
Maximizing packaging machine productivity and performance is imperative to success and is driving OEMs to adopt and invest in the latest technologies that can meet their customersâ™ challenges. At the forefront of these performance-driven technologies is an integrated control system—or programmable automation controller (PAC)—and latest-generation motion solutions.
This paper introduces the basic fundamentals of proportional-integral-derivative (PID) control theory and the characteristics of each of the PID control loops.
