RULAND BEAM TYPE SHAFT FLEXIBLE COUPLINGS

ONE PIECE ALL METAL COUPLINGS FOR SHAFTS
3 TO 12 MM

Techdrives shaft couplings include the RULAND MWS and MWC beam type couplings.  These one piece couplings are available in aluminium or stainless steel with torques 0.4 to 5 Nm and for shafts from 3 to 12 mm.  These minature couplings have a high misalignment capacity and suit speeds up to 6000 r/min


Ruland manufactures three series of zero backlash beam couplings in inch or metric dimensions with outside diameters ranging from 10 to 38mm. Flexible beam couplings in all three series are machined from a single piece of aluminium or stainless steel and feature multiple helical cuts. The multiple cut design provides higher torque capabilities and greatly reduced wind-up when compared to commodity type single beam couplings.


The MW-Series flexible beam couplings are designed specifically for precision applications, especially those that use delicate components such as encoders and tachometers. The small bearings on these components make low radial forces essential to longevity and continued high performance. The MW-series helical couplings provide extra flexibility to yield reduced bearing loads. These flexible couplings are shorter than other beam couplings and conform to industry standard lengths, fitting into confined spaces and allowing for easy retrofits in existing equipment. At the same time, the helical cut pattern continues to provide excellent torque capabilities and low wind-up. Ruland beam couplings are an economical choice for servo applications.


Type: One piece all-metal torsionally soft and backlash free couplings


Construction: Machined in one piece with two sets of spiral slots. The aluminium couplings are available with set  screws MWS or clamp hubs MWC and suit -40 to +100°C.  The stainless steel versions (with carbon steel blackened screws) are available only in MWC clamp hub version and suit -40 to +170°C.


Applications:  Small and precision drives, for example encoders. Special designs are possible

ruland beam type shaft flexible couplings

See the catalogue pages for more information

The MW-Series helical beam couplings have two sets of spiral slots, a feature that provides superior parallel misalignment capabilities compared to the single beam coupling. Angular misalignment, axial motion and any combination of all three types of misalignment are also easily accommodated by this flexible coupling.  Ruland's clamp style beam couplings have the additional benefit of dynamic balancing, due to the unique configuration of the socket head cap screws.
