BRECOflex CO. is launching a new timing belt. It’s the company’s most innovative timing belt to hit the market since its move-series in 2014. It’s called BRECOroll. Typically, toothed timing belts used for material handling tasks are very long. The belt’s load side usually lies in a support rail which causes friction. BRECOroll provides the […]

What are some linear motion options for moving multiple loads independently?
From a mechanical standpoint, one of the more challenging applications in linear motion has traditionally been to move two or more loads independently, as is required in some handling, transport, and inspection applications. While using multiple linear systems, or preassembled actuators, is a simple solution mechanically, this option typically requires a significant amount of space […]
How to account for ball and lead screw inertia during system design
When sizing a motion system with a ball or lead screw drive, the first step is to determine the screw diameter and lead that can meet the application requirements for thrust force, speed, and compressive (buckling) loads. Once the screw diameter and lead are determined, the next step is to choose a motor that can […]
New white paper for OEMs spotlights linear motion in biomedical, life sciences applications
SCHNEEBERGER Inc. announces a new white paper titled “Advancing Life Science and Biomedical Manufacturing Through Linear Motion: The OEM’s Guide.” It explores how original equipment manufacturers (OEMs) can achieve advancements in life science and biomedical manufacturing through the use of next-generation linear motion technology. Facing ongoing competitive pressures and market growth demands, life science and […]
THK introduces Type KR-RL LM Guide Actuator with ball screw
New from THK, the Type KR-RL LM Guide Actuator features a driving element that uses right/left threads and enables symmetrical movements with a single motor. Formerly available only as a custom system, THK responded to the high demand for a right/left actuator by adding the Type KR-RL to its lineup. The Type KR-RL Actuator integrates […]

Ball and lead screw drunkenness: What is it and when does it matter?
Unlike ball screws, which follow industry standards such as DIN ISO 3408, JIS B1192-1997, or ANSI-B5.48 for accuracy classifications, there are no accuracy standards for lead screws. Instead, many lead screw manufacturers have loosely adopted two of the most common ball screw lead accuracy specifications: lead deviation per 300 mm and lead deviation per revolution. Lead deviation […]
New frame size added to Curtiss-Wright integrated motor/actuator series
Curtiss-Wright’s Actuation Division has added a third frame size, the Exlar GTX060, to its GTX integrated motor/actuator series of industrial electromechanical actuators. The GTX Series actuators offer force, precision, and repeatability while eliminating or minimizing the maintenance and inefficiencies typical of fluid power alternatives. With continuous force ratings up to 2,668 N (600 lbf) and […]
What’s the difference between module and diametral pitch for rack and pinion drives?
Gear sizes are typically specified by one of two designations: module or diametral pitch. While both specifications define the size of the gear teeth, module and diametral pitch are calculated differently, with module (sometimes referred to as metric pitch) being the metric sizing standard and diametrical pitch being the Imperial (inch) sizing method. Standard modules for […]
More on the performance of roller screws
Knowing the differences between the several kinds of roller screws can help determine the best fit for an application. By Michael Boudreau, P.Eng. • Application Engineering Manager | Rollvis S.A. Planetary roller screws — also called satellite roller screws — have long been the primary choice for applications that involve heavier loads and higher forces […]
