Product Characteristics
Backlash-free elastomer jaw couplings of the RINGFEDER® GWE series are the optimum solution for all drive tasks requiring extraordinary positioning accuracy as well as highly effective damping of shocks and vibrations. They effectively compensate for radial, axial and angular shaft misalignments, are axially pluggable, puncture-proof, and electrically insulating.
The new type RINGFEDER GWE 5113, developed in close customer cooperation, is particularly convincing due to:
Low masses and even weight distribution – thanks to specially optimized hubs made of high-quality aluminum.
Superior concentricity as well as uniform, vibration- and shock-damped power transmission – due to highest manufacturing precision, symmetrical arrangement of clamping slots and screw positions as well as unslotted cam area. Convenient application even in very small, confined spaces – because of its extremely compact, short design with minimal moment of inertia.
Highly precise, absolutely backlash-free torque transmission – from 3 to 560 Newton meters (2.21 to 413.04 ft·lb).
Optimum availability – in a total of seven sizes with a wide bore diameter range from 4 to 56 millimeters (0.157 to 2.205 inch), at an attractive price and in short delivery times.
Adjustment of misalignment capability, damping behavior, and torsional stiffness as required – by means of bored and unbored elastomer spiders of four different Shore hardnesses, from 80 SH A to 64 SH D.*
Coupling hubs with keyways if needed – according to DIN 6885-1 or standard inch dimensions.
Unambiguous identification and simplified handling – thanks to obligatory laser marking that includes type designation, date of manufacture as well as screw tightening torques according to international and Anglo-American system of units.
Convenient, direct access to assembly and operation manual – by means of a mobile device via a QR code applied by laser marking (starting from coupling size 19).
Maximum operational safety in explosion-endangered areas – thanks to optional compliance with ATEX according to Product Directive 2014/34/EU and DIN EN ISO 80079-36:2016 if required.
* As standard, all coupling sizes of the RINGFEDER® GWE 5113 type are equipped with a media-resistant red elastomer spider made of high-quality polyurethane with a Shore hardness of 98 SH A.
