Constant Sleeve Series
Features
Very simple and affordable all steel form of gear coupling constructed using a single sleeve and 2 hubs
Comparatively uncomplicated set up
Precision reduce 20° strain angle gear teeth with minimal backlash
Most standard configurations are available as stock objects
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 through twelve, to accommodate bore sizes as much as and including 12.50 inches
Interference fit (conventional) and Clearance match on bores can be found
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 examined BUNA N seal style with reinforced washers bonded to the within edges which positively retain lubricant and seal the interior from outside contaminants
Reinforced rubber seals with snap rings to hold in lubricant
Two snap rings made from hardened spring steel which securely hold the coupling with each other, are simple to install or clear away, yet stand up to 100,000 pounds of finish thrust
Inch and Metric bore sizes readily available

Regular Kinds and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which incorporate C and F regular hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer styles. ’s exceptional engineering workers make it attainable to help many further coupling sorts this kind of since the Brakedrum kind, Sliding Hub type, Shear Pin form, Jordan form, and custom lengths for non normal shaft separations. Supplemental size ranges and models to meet unusual application specifications may also be manufactured by to meet marketplace demands. Material can range from normal steel to alloy steel and in some cases stainless steel. The exceptional simplicity from the coupling design and style make this all feasible.
Misalignment and End-Float Capability
The fundamental principle of Sier-Bath C and F kind couplings is just like that of other conventional versatile gear couplings. When it really is desirable to align shafts as accurately as possible, the goal of any flexible coupling would be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings use a special gear tooth geometry created specifically 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 thoroughly crowned to supply for a greater get hold of location and lower stresses below misaligned problems. The crowned tooth design and style also eliminates the majority of the end loading that happens on straight gear teeth beneath misalignment.
