Sier-Bath Steady Sleeve and Flanged Sleeve Couplings

Constant Sleeve Series
Basic and low-cost all steel style of gear coupling constructed using a single sleeve and two hubs
Comparatively basic set up
Precision minimize 20° strain angle gear teeth with minimum backlash
Most normal configurations can be found as stock goods
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 as a result of 12, to accommodate bore sizes as much as and which includes twelve.50 inches
Interference fit (common) and Clearance match on bores are available
Load Capacities range 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 layout with reinforced washers bonded towards 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 with each other, are straightforward to put in or take away, nevertheless withstand a hundred,000 lbs of end thrust
Inch and Metric bore sizes available
Flanged Sleeve Series
Patented tooth type for prolonged coupling existence
Precision lower 20° strain angle gear teeth with minimal backlash
All steel sleeves and hubs (stainless steel offered)

Conventional Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which involve C and F typical hubs and sleeves, Mill Motor hubs, Vertical design, Floating Shaft, and Spacer types. ’s excellent engineering personnel make it attainable to help lots of supplemental coupling forms such since the Brakedrum sort, Sliding Hub type, Shear Pin type, Jordan form, and custom lengths for non standard shaft separations. Supplemental size ranges and styles to meet uncommon application prerequisites also can be manufactured by to meet market place demands. Material can vary from conventional steel to alloy steel and also stainless steel. The excellent simplicity on the coupling layout make this all feasible.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F style couplings is just like that of other conventional flexible gear couplings. Even though it is actually desirable to align shafts as accurately as you possibly can, the goal of any flexible coupling will be to soak up probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings utilize a special gear tooth geometry produced especially to resolve challenges 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 provide to get a more substantial get in touch with spot and reduced stresses below misaligned conditions. The crowned tooth style also eliminates the majority of the end loading that occurs on straight gear teeth under misalignment.
