3mm, L 42.9 standards. This coupling has a four convolution bellows for higher torque and torsional stiffness capabilities than equivalent couplings with more convolutions. The addition of keyways allows for increased torque capacity and prevents the coupling from slipping on the shaft when over torqued.
7 mm) OD, Stainless This Ruland single friction bearing universal joint with set screws and keyways has 20mm x 0. It is best suited for applications requiring a short length and high torque (when compared to double universal joints of an equivalent OD).7mm) outer diameter, and a 5. This single universal joint is manufactured in the USA.
