Constant Sleeve Series
Functions
Straightforward and inexpensive all steel type of gear coupling constructed by using a single sleeve and two hubs
Comparatively straightforward installation
Precision minimize 20° strain angle gear teeth with minimal backlash
Most standard configurations can be found as stock goods
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 through 12, to accommodate bore sizes as much as and together with 12.50 inches
Interference match (standard) and Clearance match on bores are available
Load Capacities vary from 2,500 in-lbs up to 2,520,000 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 to your inside 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 of hardened spring steel which securely hold the coupling together, are uncomplicated to put in or eliminate, but stand up to 100,000 lbs of end thrust
Inch and Metric bore sizes readily available
Flanged Sleeve Series

Regular Sorts and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which contain C and F regular hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer types. ’s excellent engineering employees make it possible to help several more coupling types such since the Brakedrum kind, Sliding Hub type, Shear Pin type, Jordan variety, and custom lengths for non normal shaft separations. Extra dimension ranges and patterns to meet uncommon application needs could also be produced by to meet market place demands. Material can range from normal steel to alloy steel and in many cases stainless steel. The excellent simplicity of the coupling style make this all possible.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F type couplings is much like that of other typical flexible gear couplings. While it is actually desirable to align shafts as accurately as you possibly can, the goal of any versatile coupling is usually to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a distinctive gear tooth geometry produced exclusively to resolve problems with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are totally crowned to supply to get a greater make contact with place and reduce stresses under misaligned ailments. The crowned tooth design and style also eliminates nearly all of the finish loading that happens on straight gear teeth beneath misalignment.
