* meet API 610 requirements * can be supplied to API 671 on request These couplings have captured centre member this feature prevents spacer sub assembly. From flying off even in unlikely event of disc as well as bolt failure. Mass, Inertia, Stiffness are at max bore with standard spacer dimension C listed above. Other C dimension are available as required on request. Hub dimensions can be modified to suit special needs. Max angular misalignment 0.50 Deg /Pack .Misalignment limits are for speeds upto 3000 RPM. For higher speeds consult us. Bolt Tightening Torques- # for Disc Pack Bolts, ## for Hub Bolts .
