Inch Couplings


A new series of inch couplings from Sterling Instrument   (ISO 9001:2000+AS9100C Registered Manufacturer) feature unique lattice design which allows for very large axial, radial, and angular misalignments while transmitting high torque loads with zero backlash. The 35 couplings identified as the S50CLM and S50SCLP Series feature a maximum angular offset of 7°. Their bores range from .125” to 1.250”. 

Other bores are available on special order. Their maximum torque ranges from 5 lbf in. to 300 lbf in. The hubs are made of 6061 aluminum and the discs of 420 stainless steel or polyamide resin. The end flanges are made of 416 stainless steel. A complete series of 24 metric lattice couplings with similar specs are also available from stock.
