Ever-power Model B coupling for light to medium-duty applications
Model B couplings aren’t interchangeable with regular Ever-power couplings.
Sizes 1 1/2 through 3 1/2 with integral end band.
CENTER FLANGE BOLTING
All couplings feature precision-drilled flange bolt holes, and tight tolerance. Quality 5 flange bolts to make sure a long-lasting flange to flange and fastener suit. Uncovered bolt flanges are regular.
Shrouded bolt flanges can be supplied through size 5. Size #5 1/2 and bigger couplings are only obtainable with exposed bolt flanges.

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

Ever-power COUPLING Features & Benefits

IMPROVED SOFT SEAL presents superior sealing in misaligned conditions.
UNIQUE TOOTH FORM using a 40° pressure angle, distributes the load over a larger area than couplings designed to use a 20° pressure position.
FULL TOOTH ENGAGEMENT reduces uneven wear on teeth that results in longer life plus improved performance.
QUALITY EXPOSED FASTENERS consists of SAE Quality 5 bolts with hex nuts and lock washers. Installation is easy, without special tools. Shrouded bolts optional.
CLEAR Corrosion INHIBITIVE AND CORROSION RESISTANT Finish off protects coupling in regular industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with large bore capabilities or stock finish bored.
OPTIONAL PILOT RINGS provides positive register between identical halves. Eliminates selective assembly needed in male, feminine sleeves.
INTERCHANGEABLE by fifty percent coupling with competitive coupling designs.
HIGHER MISALIGNMENT CAPABILITY sizes 1-7 compensate for up to ±1 1/2° static angular misalignment per equipment mesh.
Series H Gear Couplings

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

The straight-faced, involute stub tooth form can be used in the Series H coupling, sizes 8 to 30. This tooth form distributes contact pressures over the full length of the hub tooth, to greatest develop the needed lubricating film, reducing tooth wear and extending coupling support life for years of operation. THE FINISH Rings are removable for simple assembly and to allow inspection of the apparatus sets.
Ever-power Gear Couplings

The Ever-power design, using its life time all-metal end band, provides up to 300% greater lubricant capacity. This means that longer periods between relubrication could be scheduled.

The all-metallic end ring, used exclusively in Ever-power couplings, eliminates the necessity for any type of perishable lube seal (o-rings, lip seals, cork gaskets, etc.). The end ring not only supplies the dam over which lubricant must movement to escape, but it additionally pilots the sleeve with respect to the hub during start-up and shut-down functions. It further eliminates partial tooth disengagement with resulting tooth overloads by giving sleeve tooth which are flush against the inside wall of the end ring.

It is the only coupling designed to use oil lubrication.

To make sure that your couplings provide Maximum Life, usually specify Ever-power couplings, with the all-metal end ring.

The Straight-Faced involute hub tooth form featured in the Ever-power coupling is practically unique in the industry today. It is this tooth form that distributes tooth contact pressures across the full length of the hub tooth, greatest developing the needed hydrodynamic lube film, reducing tooth use and extending coupling existence. It is the only hub tooth form obtainable in the standard Ever-power coupling line.

Ever-power Gear Couplings

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

OPTIONAL PILOT RINGS
The standard Ever-powercoupling consists of two identical half couplings. Optional precision steel pilot rings can be found when even more accurate centering of the two sleeves is required.

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

Ever-power POWERLIGN
This flangeless design transmits identical torques as the standard Ever-power Coupling. Having a smaller sized outside diameter, however, it is more small, lighter, and may run at better speeds. This alternative could be chosen for applications where space is limited.

SERIES H Features & Benefits

Higher Misalignment Capability
Sizes 1-7 compensate for up to ±1 1/2° static angular misalignment per equipment mesh.
Minimizing working misalignment will maximize the life of the coupling. Make reference to the Set up and Alignment Guidelines for alignment recommendations.
Larger Bore Capabilities allow the most economical size selection for shafts up to 10 5/8″.
Higher Torque Ratings due to larger tooth pitch diameters than additional couplings.
Versatility for the reason that Series H’s are interchangeable by fifty percent coupling with competitive coupling styles.
1 1/2° Curved-Face Teeth certainly are a primary feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth type with flank, suggestion, and root curvature. When
used in combination with the straight faced sleeve teeth, these 1 1/2° curved face hubs offer improved shaft misalignment capability
CENTER FLANGE BOLTING
All couplings feature precision-drilled flange bolt holes, and tight tolerance Quality 5 flange bolts to assure a long-lasting flange to flange and fastener fit. Exposed bolt flanges are
standard. Shrouded bolt flanges can be provided through size 5. Size #5 1/2 and larger couplings are only available with exposed bolt flanges.

LUBRICATION
Each sleeve flange is supplied with two pipe plugs 180° aside. This permits assembly of a complete flex coupling with four lube plugs positioned every 90°, facilitating lubrication. The lube seal is definitely 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 equipment coupling is available in two basic product lines:

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