Sier-Bath Constant Sleeve and Flanged Sleeve Couplings

Constant Sleeve Series
Basic and inexpensive all steel kind of gear coupling constructed using a single sleeve and 2 hubs
Comparatively straightforward installation
Precision reduce 20° strain angle gear teeth with minimum backlash
Most typical configurations can be found as stock objects
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 through twelve, to accommodate bore sizes up to and including 12.50 inches
Interference fit (regular) and Clearance match on bores can be found
Load Capacities vary from 2,500 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 design with reinforced washers bonded for the 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 from hardened spring steel which securely hold the coupling collectively, are effortless to install or remove, yet withstand 100,000 lbs of finish thrust
Inch and Metric bore sizes out there
Flanged Sleeve Series
Patented tooth kind for extended coupling daily life
Precision cut 20° pressure angle gear teeth with minimal backlash
All steel sleeves and hubs (stainless steel obtainable)
Models for applications requiring horizontal and vertical orientation
Most common configurations are available as stock items
Angular misalignment of 1-1/2° per gear mesh (flex-plane) as much as size 5.five, 3/4° for sizes 6 and above
Coupling sizes available through dimension thirty to accommodate bore sizes up to and like 44 inches
Interference match (standard) and Clearance match on bores are available
Load capacities vary from seven,600 in-lbs up to 47,269,000 in-lbs
Exposed bolts standard on all sizes, shrouded available by request as much as size 6
Typical bolts supplied are handled for being corrosion resistant
Flanged sleeve couplings are interchangeable with sector specifications
Piloted gear match for higher speeds and much less vibration
Labyrinth all steel seal layout in FL series
Inch and Metric bore sizes readily available
Standard Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which contain C and F typical hubs and sleeves, Mill Motor hubs, Vertical style, Floating Shaft, and Spacer patterns. ’s fantastic engineering personnel make it attainable to support several further coupling varieties such as the Brakedrum type, Sliding Hub kind, Shear Pin form, Jordan type, and customized lengths for non regular shaft separations. Further size ranges and styles to meet uncommon application requirements could also be produced by to meet market demands. Material can vary from regular steel to alloy steel as well as stainless steel. The outstanding simplicity with the coupling design make this all achievable.
Misalignment and End-Float Capability
The basic principle of Sier-Bath C and F style couplings is much like that of other typical versatile gear couplings. Although it is desirable to align shafts as accurately as you possibly can, the purpose of any flexible coupling will be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a distinctive gear tooth geometry designed especially 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 completely crowned to supply for any greater get hold of region and reduced stresses underneath misaligned ailments. The crowned tooth style and design also eliminates the majority of the end loading that takes place on straight gear teeth underneath misalignment.
