Ever-power Model B coupling for light to medium-duty applications
Model B couplings aren’t interchangeable with standard Ever-power couplings.
Sizes 1 1/2 through 3 1/2 with integral end band.
All couplings feature precision-drilled flange bolt holes, and tight tolerance. Quality 5 flange bolts to assure a long-enduring flange to flange and fastener match. Exposed bolt flanges are regular.
Shrouded bolt flanges can be provided through size 5. Size #5 1/2 and bigger couplings are only available with uncovered bolt flanges.

Ever-power couplings are designed for ± 1/2° static misalignment per half coupling. Minimizing operating misalignment will maximize the life span of the coupling. Refer to the Installation and Alignment Guidelines for alignment recommendations.

Ever-power COUPLING Features & Benefits

IMPROVED SOFT SEAL gives superior sealing less than misaligned conditions.
UNIQUE TOOTH FORM utilizing a 40° pressure angle, distributes the load over a larger area than couplings designed to use a 20° pressure angle.
Total TOOTH ENGAGEMENT reduces uneven put on on tooth that results in longer life plus improved performance.
QUALITY EXPOSED FASTENERS contains SAE Quality 5 bolts with hex nuts and lock washers. Installation is easy, without special tools. Shrouded bolts optional.
CLEAR RUST INHIBITIVE AND CORROSION RESISTANT FINISH protects coupling in normal industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with large bore features or stock finish bored.
OPTIONAL PILOT RINGS provides positive register between identical halves. Eliminates selective assembly needed in male, female sleeves.
INTERCHANGEABLE by half coupling with competitive coupling designs.
HIGHER MISALIGNMENT CAPABILITY sizes 1-7 compensate for up to ±1 1/2° static angular misalignment per gear mesh.
Series H Gear Couplings

Series H couplings of Size 8 to 30 are created for ±1/2° misalignment per flex half coupling, to pay for misalignment between your shafts in a full-flex coupling. Series H couplings can be supplied in full-flex, flex-rigid, floating shaft and spacer arrangements and also custom designs. Only exposed bolt flanges are available in sizes 8 to 30.

The straight-faced, involute stub tooth form is utilized in the Series H coupling, sizes 8 to 30. This tooth form distributes contact pressures across the full amount of the hub tooth, to greatest develop the required lubricating film, reducing tooth use and extending coupling services life for a long time of operation. The End Rings are detachable for ease of assembly and to allow inspection of the gear sets.
Ever-power Gear Couplings

The Ever-power design, with its lifetime all-metal end ring, provides up to 300% greater lubricant capacity. This means that longer intervals between relubrication could be scheduled.

The all-steel end ring, used exclusively in Ever-power couplings, eliminates the necessity for any kind of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The finish ring not only provides the dam over which lubricant must circulation to escape, nonetheless it additionally pilots the sleeve with regards to the hub during start-up and shut-down functions. It further eliminates partial tooth disengagement with resulting tooth overloads by providing sleeve teeth which are flush against the within wall of the finish ring.

It’s the only coupling made to use oil lubrication.

To be sure that your couplings provide Maximum Life, generally specify Ever-power couplings, with the all-metal end band.

The Straight-Faced involute hub tooth form featured in the Ever-power coupling is virtually unique in the industry today. It is this tooth type that distributes tooth contact pressures across the full length of the hub tooth, greatest developing the needed hydrodynamic lube film, minimizing tooth put on and extending coupling existence. It is the just hub tooth form available in the typical Ever-power coupling line.

Ever-power Gear Couplings

The Ever-power gear coupling has been designed with full duration tooth engagement with the inherent consequence of longer existence and improved performance.

The standard Ever-powercoupling contains two identical half couplings. Optional precision metal pilot rings are available when even more accurate centering of both sleeves is required.

Competitive gear couplings include an O-ring seal. To be able to conform with today’s high misalignment capacities, this O-ring must fit into a groove that is larger than the band.Ever-power couplings make use of a truly high misalignment seal that seals remarkably under misaligned circumstances.

Ever-power POWERLIGN
This flangeless design transmits identical torques as the standard Ever-power Coupling. Having a smaller outside diameter, however, it is more compact, lighter, and will run at higher speeds. This alternative could be selected for applications where space is bound.

SERIES H Features & Benefits

Higher Misalignment Capability
Sizes 1-7 compensate for up to ±1 1/2° static angular misalignment per gear mesh.
Minimizing working misalignment will increase the life of the coupling. Make reference to the Installation and Alignment Instructions for alignment recommendations.
Larger Bore Capabilities permit the most economical size selection for shafts up to 10 5/8″.
Higher Torque Ratings due to larger tooth pitch diameters than other couplings.
Versatility for the reason that Series H’s are interchangeable by half coupling with competitive coupling styles.
1 1/2° Curved-Face Teeth certainly are a prime feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth type with flank, tip, and root curvature. When
used in combination with the straight faced sleeve teeth, these 1 1/2° curved encounter hubs offer elevated shaft misalignment capability
All couplings feature precision-drilled flange bolt holes, and tight tolerance Grade 5 flange bolts to make sure a long-lasting flange to flange and fastener fit. Exposed bolt flanges are
standard. Shrouded bolt flanges can be supplied through size 5. Size #5 1/2 and bigger couplings are only available with exposed bolt flanges.

Each sleeve flange comes with two pipe plugs 180° apart. This permits assembly of a complete flex coupling with four lube plugs positioned every 90°, facilitating lubrication. The lube seal is normally a Buna-N O-ring to help retain grease and exclude contaminants. KHP or KSG coupling greases are recommended in order to obtain maximum working life.

Ever-power COUPLING Features & Benefits

The Ever-power gear coupling comes in two basic products:

Ever-powercoupling for moderate to heavy-duty applications
Sizes 1 1/2 through 7 with integral end ring.
Sizes 8 through 30 with bolt-on end ring.
