Conventional Sorts and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F standard hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer 
types. ’s fantastic engineering staff make it attainable to help a lot of extra coupling forms such as the Brakedrum form, Sliding Hub sort, Shear Pin form, Jordan sort, and customized lengths for non standard shaft separations. Added dimension ranges and types to meet uncommon application prerequisites may also be produced by to meet market demands. Material can range from regular steel to alloy steel and also stainless steel. The excellent simplicity from the coupling design make this all feasible.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F variety couplings is similar to that of other conventional versatile gear couplings. Whilst it’s desirable to align shafts as accurately as you possibly can, the purpose of any versatile coupling is to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a unique gear tooth geometry produced especially to resolve difficulties with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are completely crowned to supply to get a more substantial contact area and decrease stresses below misaligned ailments. The crowned tooth design and style also eliminates the majority of the finish loading that takes place on straight gear teeth below misalignment.
