2. Ringfeder GWE 5113 Coupling – Backlash-free, superior concentricity

RINGFEDER^® Servo Couplings GWE 5113 is a “jaw coupling” type elastomer coupling designed with single-slit clamping hubs, super compact size, very high concentricity to help smooth transmission, reduce vibration – shock load and ensure position accuracy. 7 size range, moment 3–560 Nm, maximum speed 4,000–15,000 rpm, shaft diameter 4–56 mm.

2.1. Technical highlights

– Absolutely backlash-free thanks to the tight fitting design of the elastomer “spider” → maintains position accurately even when reversing.
– Vibration reduction – shock loading, compensation for shaft misalignment (radial/axial/angular), no longitudinal shaft when mounting (axially pluggable), fail-safe construction and insulation.
– Outstanding concentricity thanks to mass-optimized aluminum hub, symmetrical clamping groove arrangement & screw position, non-slotted washers → even torque transmission, low vibration.
– Standard spider Red Polyurethane 98 Sh A, optional 4 hardness levels from 80 Sh A to 64 Sh D to fine-tune the torsional stiffness – damping of the drive system.
– Mandatory laser engraving (type code, production date, screw tightening torque according to both SI/Imperial) and QR code leading to manual (from size 19) → convenient retrieval & installation.
– ATEX option according to Directive 2014/34/EU and DIN EN ISO 80079-36:2016 for potentially explosive environments.

3. Why choose GWE 5113 for servo system & precision transmission?

– High concentricity + low inertia: aluminum hub optimizes mass to reduce inertia load, fast response – smooth.
– Customizable torsional stiffness: choose spider according to stiffness (Shore) to balance between angular accuracy and vibration reduction.
– Reliable & easy to maintain: fail-safe structure, laser engraved parameters, QR manual; ATEX available when needed.

3.1. Quick selection guide

– Step 1 – Calculate required torque: TKn = (9950xP[kW]) / n(v/ph) × load factor according to working characteristics.
– Step 2 – Choose rubber stiffness of coupling:
+ Stiffness (Sh A) → good shock absorption, suitable for packaging machines/conveyors.
+ Stiffness (Sh D) → high torsional stiffness, servo response/position control.
– Step 3 – Check bore range, speed, installation dimensions according to Catalog GWE 5113.

3.2. Installation & operation

– Keep shaft tolerance g6–h7, align within allowable offset limits; tighten screws according to recommended torque engraved on the GWE 5113 coupling hub.
– Select spider according to environment (heat/chemical) and desired stiffness; for explosion-prone areas, select ATEX version.
