Straightforward and cheap all steel form of gear coupling constructed using a single sleeve and two hubs
Comparatively very simple set up
Precision reduce 20° pressure angle gear teeth with minimal backlash
Most common configurations can be found as stock items
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 by means of 12, to accommodate bore sizes up to and such as 12.50 inches
Interference match (common) and Clearance fit on bores are available
Load Capacities vary from two,500 in-lbs up to two,520,000 in-lbs
Models for applications requiring horizontal and vertical orientation, full-flex, flex-rigid, mill-motor, disengagement, sliding hubs, Shear Pin, floating shaft, and spacers
Patented and tested BUNA N seal design with reinforced washers bonded towards the inside 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 simple to install or eliminate, nonetheless withstand one hundred,000 lbs of end thrust
Inch and Metric bore sizes accessible

Regular Types and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which include C and F regular hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer models. ’s excellent engineering staff make it feasible to help a lot of extra coupling kinds this kind of as the Brakedrum kind, Sliding Hub sort, Shear Pin kind, Jordan style, and custom lengths for non standard shaft separations. Additional size ranges and patterns to meet uncommon application prerequisites may also be produced by to meet industry demands. Materials can range from standard steel to alloy steel and in many cases stainless steel. The outstanding simplicity with the coupling design and style make this all feasible.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F style couplings is much like that of other typical flexible gear couplings. Whilst it’s desirable to align shafts as accurately as is possible, the purpose of any versatile coupling is usually to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a exclusive gear tooth geometry developed particularly to resolve issues with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are entirely crowned to supply to get a more substantial contact place and reduce stresses under misaligned situations. The crowned tooth design also eliminates the majority of the end loading that happens on straight gear teeth beneath misalignment.
