MWC15-3-3-SS, Ruland

Stainless Steel Flexible Shaft Couplings Designed to perform where higher speeds, greater misalignment, and limited lubrication would exceed the capabilities of other couplings. Each coupling is manufactured as one piece, thereby eliminating mechanical joints and possible failure points.Two fixing styles available:,Typical applications include encoders, stepper motors, robotics, measuring instruments, servo systems, pumps, valves, fans etc., (i) Set Screw style is secured using one grub-screw per shaft (staggered at 120°) , (ii) Clamp style fixing uses one socket head cap screw per shaft. Constant velocity couplings with high torque capacity and zero backlash Torsionally rigid one-piece construction Not temperature sensitive High or low speed operation and reversible No lubrication required Up to 3° of axial misalignment allowable Note The coupling shown represents the clamp style fixing

RS PRO 10mm Aluminium BCC Flexible Beam Coupling A BCC series six beam coupling for use where a degree of motion is required between shafts. Each coupling is manufactured as a single piece eliminating mechanical joints and possible failure points. The clamp fastening beam coupling is constructed from Aluminium for strength and will delivery increased torque capacity with higher torsional stiffness. The BCC series coupling is designed with two sets of cuts around the centre accommodating a higher level of parallel misalignment compared to single beam couplings. The BCC series coupling features a M4 socket head cap screw at each end for easy installation.

Ruland Oldham Coupling Hub - Clamp Style Ruland Clamp Style Oldham Couplings are ideally suited to enable shafts to be coupled with a small amount of axial and angular misalignment present. The three-piece design consists of two hubs linked by a centre torque disc. The Clamp Style Hubs are manufactured from black anodised aluminium, with replaceable centre discs manufactured from acetal or nylon. Oldham couplings are ideal for light industrial and motion control applications, and, due to their unique design, Oldham couplings offer the ability to protect machinery from torque overload forces (acting as torque limiters), with centre discs that are able to break cleanly. 2 hubs and 1 torque disc required per assembly Technical specification Size Code Hub Depth (mm) Depth of Bore (mm) Hub Outside Diameter (mm) Overall Coupling Assembly Length (mm) Set Screws 19 9.7 9.7 19.1 25.4 M2.5 25 11.9 31.8 25.4 11.9 M3 33 15 47.6 33.3 15 M3 41 18 50.8 41.3 18 M4 51 20.8 59.7 50.8 20.8 M5 57 28.7 78.7 57.2 28.7 M6 Note Not supplied as a complete unit ; 2 Hubs and 1Torque Disc required per assembly. Ruland Oldham Style Couplings Paradrive™ couplings are ideal for motion control applications, especially those utilising stepper or servo motors. Their low inertia design is ideally suited to higher speed applications and where electrical isolation is also required. Small angular and axial misalignments may be accommodated. Securing: 13mm and 19mm anodised aluminium hubs are secured to the shafts with one set screw on each end. 33mm, 35mm and 41mm hubs have 2 set screws set 90° apart
