Multiply MR^2 Values by 4 to obtain GD^2 values. Weight & Inertia are at max bore with smallest standard spacer. For other spacers use weight & inertia change values to calculate actual figures. Maximum permissible angular misalignment is 1.0 deg for 1500 RPM and 0.5 deg for 3000 RPM at each disc Pack. Standard Construction has hubs, spacers of class2 forged steel IS2004 and Disc Packs of Stainless steel. For plated bolts reduce Tightening Torques by 20%. Spacer Dimensions other than standard spacers can also be supplied.
