SDP/SI offers an off-the-shelf series of inch and metric size splined sleeve type flexible couplings that offer torsional resiliency to absorb load pulsations and shocks in instrumentation applications. The couplings can accommodate up to 7 degrees of angular misalignment and transmit up to 1/2 hp at 1750 rpm. Read more...

A new series of inch couplings from SDP/SI feature unique lattice design allows for very large axial, radial, and angular misalignments while transmitting high torque loads with zero backlash. The 34 couplings identified as the S50CLM-... and S50CLP-... inch series, feature a maximum angular offset of 7°. A complete series of 24 metric lattice couplings with similar spe... Read more...

SDP/SI offers a large selection of precision ground shafting to fit a wide variety of applications. With straightness as low as .0002 inches per inch, they provide highly precise alignment where necessary. Diameters start as low as .0311”, and shaft lengths as low as 1”, so they can be used for miniature applications as well. Read more...
