Sier-Bath Constant Sleeve and Flanged Sleeve Couplings

Steady Sleeve Series
Simple and inexpensive all steel style of gear coupling constructed which has a single sleeve and 2 hubs
Comparatively straightforward installation
Precision minimize 20° strain angle gear teeth with minimal backlash
Most common configurations can be found as stock things
Angular misalignment of 1/2° per gear mesh (flex-plane)
Sizes 7/8 by way of twelve, to accommodate bore sizes up to and like twelve.50 inches
Interference match (typical) and Clearance match on bores can be found
Load Capacities range from two,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 examined BUNA N seal style and design with reinforced washers bonded on 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 made of hardened spring steel which securely hold the coupling collectively, are uncomplicated to put in or take away, yet withstand one hundred,000 lbs of end thrust
Inch and Metric bore sizes out there
Flanged Sleeve Series
Patented tooth kind for prolonged coupling daily life
Precision lower 20° stress angle gear teeth with minimal backlash
All steel sleeves and hubs (stainless steel out there)
Styles for applications requiring horizontal and vertical orientation
Most standard configurations are available as stock products
Angular misalignment of 1-1/2° per gear mesh (flex-plane) up to size five.five, 3/4° for sizes 6 and above
Coupling sizes obtainable as a result of dimension 30 to accommodate bore sizes up to and including 44 inches
Interference fit (common) and Clearance match on bores are available
Load capacities range from 7,600 in-lbs up to 47,269,000 in-lbs
Exposed bolts conventional on all sizes, shrouded available by request as much as dimension six
Normal bolts provided are handled to get corrosion resistant
Flanged sleeve couplings are interchangeable with field standards
Piloted gear match for greater speeds and significantly less vibration
Labyrinth all steel seal design and style in FL series
Inch and Metric bore sizes accessible
Standard Styles and Sizes
Sier-Bath couplings are stocked in an assortment of configurations which consist of C and F standard hubs and sleeves, Mill Motor hubs, Vertical type, Floating Shaft, and Spacer styles. ’s excellent engineering staff make it possible to help a lot of additional coupling sorts this kind of as the Brakedrum form, Sliding Hub type, Shear Pin form, Jordan form, and custom lengths for non standard shaft separations. Additional dimension ranges and styles to meet unusual application demands can also be produced by to meet industry demands. Materials can vary from conventional steel to alloy steel and even stainless steel. The outstanding simplicity on the coupling layout make this all probable.
Misalignment and End-Float Capability
The essential principle of Sier-Bath C and F sort couplings is just like that of other conventional flexible gear couplings. Though it can be desirable to align shafts as accurately as you can, the purpose of any flexible coupling would be to absorb probable angular, parallel, and axial (end-float) misalignment. Sier-Bath couplings make use of a unique gear tooth geometry formulated specifically to resolve difficulties with shaft misalignment and accommodate from 1/2° to 1-1/2° per gear mesh or flex plane. The hub teeth are absolutely crowned to supply for a bigger get in touch with region and reduced stresses underneath misaligned ailments. The crowned tooth design and style also eliminates most of the end loading that happens on straight gear teeth under misalignment.
