Comparatively simple set up
Precision minimize 20° stress angle gear teeth with minimal backlash
Most typical configurations are available as stock objects
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 via twelve, to accommodate bore sizes up to and which includes 12.50 inches
Interference fit (conventional) and Clearance fit on bores are available
Load Capacities vary from 2,500 in-lbs as much as two,520,000 in-lbs
Types for applications requiring horizontal and vertical orientation, full-flex, flex-rigid, mill-motor, disengagement, sliding hubs, Shear Pin, floating shaft, and spacers
Patented and examined BUNA N seal design with reinforced washers bonded to the within edges which positively retain lubricant and seal the interior from outdoors contaminants
Reinforced rubber seals with snap rings to hold in lubricant
Two snap rings manufactured from hardened spring steel which securely hold the coupling together, are quick to install or clear away, but stand up to a hundred,000 pounds of finish thrust
Inch and Metric bore sizes obtainable

Conventional Types and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which consist of C and F common hubs and sleeves, Mill Motor hubs, Vertical type, Floating Shaft, and Spacer models. ’s superb engineering employees make it feasible to help many further coupling forms such as the Brakedrum style, Sliding Hub sort, Shear Pin form, Jordan form, and customized lengths for non typical shaft separations. Further size ranges and patterns to meet unusual application specifications may also be produced by to meet industry demands. Materials can vary from standard steel to alloy steel as well as stainless steel. The exceptional simplicity of your coupling design and style make this all attainable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F variety couplings is much like that of other typical flexible gear couplings. Although it can be desirable to align shafts as accurately as you possibly can, the purpose of any versatile coupling would be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a special gear tooth geometry designed particularly to resolve concerns with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are absolutely crowned to provide for any greater get hold of place and reduce stresses beneath misaligned circumstances. The crowned tooth design also eliminates the vast majority of the end loading that happens on straight gear teeth underneath misalignment.
