Renishaw Offers Self-Centering Scale Discs for Quick Setup

Renishaw has launched a new metal scale disc for its Atom DX encoder series: the Centrum CSF40 scale. Centrum CSF40 stainless-steel, self-centering scale discs are said to be quick and easy to install because of their mounting features that automatically center the scale when pushed onto an appropriately sized shaft. These alignment features enable fast installation with consistent installed accuracy.

Centrum scale discs are quicker and easier to install due to the specially designed flexures that act like springs to align the disc to the shaft. Mounting of the Centrum disc is completed by the addition of three bolts, tightened to pre-set torque values, with no additional gauges or setup devices required. Centrum discs are made from robust stainless steel, which is resilient and easy to clean. With 40-μm pitch incremental graduations, CSF40 discs are available in a range of sizes with external diameters from 38.4 mm to 120 mm. An Atom encoder variant compatible with Centrum scale discs is also planned.

Renishaw Centrum CSF40 encoder scales are manufactured in-house using strict quality-controlled processes that are certified to ISO 9001:2015. Renishaw encoder systems are backed by a global sales and support network of subsidiary companies in 36 countries.

“Our new stainless-steel disc scale, Centrum CSF40, incorporates three pairs of optimized alignment flexures to enhance the speed and ease of rotary encoder scale installation,” says Ben Carruthers-Watt, senior design engineer for Centrum. “The self-aligning feature eliminates the need for manual alignment of the encoder disc. This significantly minimizes installation time and simplifies the assembly process.”
