How INGIANT Controls Slip Ring Quality and Service Life
A slip ring is a wear part on a machine that is expected not to wear. Contact material, test procedure and the chosen quality grade are what decide whether it reaches the target revolutions.
Quality and Reliability
Contact material
Precious metal ring and brush pairs, with fibre brush bundle contact structures on the data-carrying designs.
Measured values
Insulation resistance of 1000 MΩ or more at 500 VDC, insulation strength of 1500 VAC at 50 Hz for 60 s at 2 mA, and dynamic resistance variation below 10 mΩ.
Test equipment
Testing equipment and procedures verify performance and durability before units are delivered.
Quality grades
Grade S Standard, Grade I Industrial and Grade P Premium, agreed with the customer against the expected duty, with service life up to one billion revolutions.
Certification
ISO 9001, GJB9001C and GB/T 19001-2008 / ISO 9001:2008.
Warranty
12 months from date of sale, with free repair or replacement for quality problems not caused by human damage.
Support
Technical information and technical training support are provided on a regular basis.
