Linear drive is even more versatile
The Amacoil/Uhing model RS linear drive now offers a wider range of linear pitch settings for improved versatility and functionality in meeting linear motion application requirements.
Linear drive assembly reduces downtime
Amacoil/Uhing has introduced a linear drive assembly providing mechanical control over linear speed and travel direction.
Rolling ring drives use specially machined bearings which eliminate backlash from linear motion.
Additionally, the drive head in a rolling ring system may be manually positioned on the shaft, without "jogging" the system on and off.
Dimensions of both rolling ring drives and assemblies are provided by mechanical drawings and specifications charts.

A novel linear motion system requires no programming and has mechanically triggered controls which automatically adjust the tool head stroke length and reversal, "on the fly".
All-mechanical ramp down for linear system
The K option is a new linear motion assembly from Amacoil/Uhing that enables purely mechanical control over ramp-down speed prior to reversal of the drive head.
Full colour photos and illustrations support detailed text covering how rolling ring engineering works, what applications are best suited to the technology, and Amacoil's rolling ring system design and implementation services.
Featured applications include test and measurement equipment, indexing machines, x-y table movement and specialised motion control assemblies such as door opening and throttle arm control systems.
Complete engineering information is presented including tables and formulas for calculating technical parameters such as axial thrust, shaft sag, drive shaft speed and predicted lifespan of rolling ring assemblies.
The brochure also offers photographs and descriptive text on the full line of Amacoil/Uhing rolling ring linear motion products including RG reciprocating linear drives, shaft collar clamping systems, PLC-controlled assemblies and an opto-sensor system used to improve spooling and winding procedures.
The Amacoil/Uhing RS linear drive featured in the brochure has five pitch settings for improved flexibility in meeting linear motion system pitch requirements.
Amacoil/Uhing RS rolling ring linear drives achieve linear speeds of up to 5ft/s over distances up to 16ft.
Axial thrust is up to 500lb and repeatable accuracy is to within +0.0004in, depending on the type of controls used.
The only maintenance required is periodic, light lubrication of the shaft.
Since the drive shaft is threadless, its smooth surface remains clean and clog-free without the design and fabrication of a protective bellows assembly.
An optional "free-movement" lever permits manual positioning of the drive head while the system is stopped.
Pricing for RS drives starts at less than $200; assemblies (not including motors and controls) start at $500.
Delivery ranges from one to several weeks depending on the level of customisation required.
