There are numerous ways to classify the performance of linear positioning devices such as ball screws, belts, and rack and pinion systems, but the terminology can be confusing. The two most common terms, accuracy and repeatability, and are often used interchangeably. When someone says that a ball screw is very accurate, they may really mean that […]
What are the main types of linear actuators?
Updated August 2017 || Linear actuators come in myriad configurations to suit almost any application, environment or industry. They’re primarily categorized by their drive mechanism; then manufacturers use other features such as the type of guide and housing to further differentiate them. Below is an explanation of the most common linear actuator categories. Belt-driven and […]
A selection guide for linear systems
Gone are the days when machine designers and builders had to choose between constructing their own linear system from scratch or settling for a limited range of pre-assembled systems that, in most cases, were an imperfect fit for their application. Manufacturers today offer systems based on a range of drive mechanisms—ball screws, belts, rack and pinions, linear motors, […]
New Timing Belt Drive Resists Sag over Long Travel
Aston, PA – The new model AZ1040 drive is the most recent extension to the Amacoil-Uhing line of timing belt drives used for smooth linear motion in positioning and indexing applications. The drive features a one-piece aluminum profile extrusion which serves as the belt housing. T-slots and receiver grooves for the load carriage guide bars […]
EXCEL-A-BELT Miniature Drive Belt System
Something new in the miniature drive belt system from NBK. After years of testing, NBK’s system offers a unique arched tooth profile with zero backlash which enables the system to run longer, cleaner, and quieter than common drive belts in use today. The key to the new tooth profile, which allows for high accuracy positioning […]
