IP65 slip rings for flow packaging machines offer long service life and minimal maintenance


Sertecnica’s SVTS B Series slip ring assemblies provide machine builders with continuously rotating electrical joints that can extend their service life to 100 million revolutions at high speeds. Targeted at demanding industrial applications in high-throughput production machinery, this series features gold alloy multi-fiber brushes and precious metal rings in IP65 fully sealed ABS/aluminum/stainless steel housings to ensure highly reliable transmission of power and instrument signals through rotating structures.

The SVTS B 03 variant with a diameter of 70 mm is designed to transmit power to the rotating heat sealing blades in flow packaging machines and to process the temperature signal output to the machine controller. This model is equipped with three 400V/20 A circuits and two 240V/2A signal circuits, and has full sales and technical support from Serotecnica’s UK distribution partner, Heason Technology. Its 22 mm diameter through-hole allows direct mounting on the drive shaft of the rotating blade via four M3 set screws. Two versions are available for machine washdown use: fully encapsulated and IP65 sealed or partially encapsulated to IP65 when installed – both have sealed cable gland electrical connections, are lower powered and provide a customer specified number of slip ring “channels” .

Servotecnica’s SVTS fiber tow technology provides lower friction and longer life than traditional high-wear carbon brush designs used by other manufacturers. The multi-fiber bundle requires no lubricant and produces only negligible debris, significantly reducing the need for routine maintenance or frequent brush replacement. High-precision stainless steel support bearings also help ensure long operating life, and a specified rated speed capability of 400 rpm is available for use on high-throughput machinery. Other benefits include improved signal quality, as (up to ten) individual gold alloy wire brushes ensure multiple points of contact with the slip ring, and a higher ability to handle high transient loads, in addition to better resistance to shock and Vibration capability. Other versions of the SVTS-B Series feature quick-action male terminal connectors that do not require sealing.

Servotecnica’s wide range of slip rings and rotary joints includes standard and custom models with specifiable multiple channels for power and signal transmission as well as Ethernet, radio, fiber optic and fluid transmission – available in housings or partial housings, explosion-proof, Highly rugged, open style and flat slip ring assembly. In addition to packaging machinery and industrial manufacturing plants, other industries served include wind turbines, cranes and hoists, process control, medical and pharmaceutical production machinery, amusement equipment, machine tools and more.

Heason Technology is ready to add machine customization using Serotecnica’s slip ring components. As a systems integrator with its own in-house design and production facilities and distribution partnerships with select global automation component suppliers, Heason also provides and supports motion control equipment from the component level to complete systems, including steppers and Servo motors and drives, motion hardware and software, gear devices, linear bearings, mechanical positioning mechanisms, and more.
