Ever-power Model B coupling for light to medium-duty applications
Model B couplings are not interchangeable with standard Ever-power couplings.
Sizes 1 1/2 through 3 1/2 with integral end ring.
CENTER FLANGE BOLTING
All couplings feature precision-drilled flange bolt holes, and tight tolerance. Grade 5 flange bolts to assure a long-lasting flange to flange and fastener fit. Uncovered bolt flanges are standard.
Shrouded bolt flanges could be supplied through size 5. Size #5 1/2 and larger couplings are only available with exposed bolt flanges.

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

Ever-power COUPLING Features & Benefits

IMPROVED SOFT SEAL offers 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 wear on teeth that results in longer existence plus improved performance.
QUALITY EXPOSED FASTENERS consists of SAE Grade 5 bolts with hex nuts and lock washers. Installation is easy, without special tools. Shrouded bolts optional.
CLEAR RUST INHIBITIVE AND CORROSION RESISTANT End protects coupling in regular industrial environments.
AVAILABLE OFF-THE-SHELF in reborables with huge bore capabilities or stock finish bored.
OPTIONAL PILOT RINGS provides positive register between similar halves. Eliminates selective assembly required in male, feminine sleeves.
INTERCHANGEABLE by half coupling with competitive coupling designs.
HIGHER MISALIGNMENT Ability sizes 1-7 compensate for ±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 your shafts in a full-flex coupling. Series H couplings can be supplied in full-flex, flex-rigid, floating shaft and spacer plans as well as custom designs. Only exposed bolt flanges can be found 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 type distributes contact pressures over the full amount of the hub tooth, to greatest develop the needed lubricating film, minimizing tooth put on and extending coupling service life for years of operation. The End Rings are detachable for simple assembly and to enable inspection of the apparatus sets.
Ever-power Gear Couplings

The Ever-power design, with its lifetime all-metal end ring, provides up to 300% greater lubricant capacity. This implies 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 movement to escape, nonetheless it additionally pilots the sleeve with regards to the hub during start-up and shut-down operations. It further eliminates partial tooth disengagement with resulting tooth overloads by giving sleeve teeth which are flush against the inside wall of the finish ring.

It is the only coupling made to use oil lubrication.

To make sure that your couplings provide Optimum Life, always specify Ever-power couplings, with the all-metal end band.

The Straight-Faced involute hub tooth form featured in the Ever-power coupling is practically unique in the market today. It really is this tooth type that distributes tooth contact pressures over the full length of the hub tooth, best developing the needed hydrodynamic lube film, minimizing tooth put on and extending coupling lifestyle. It is the only hub tooth form available in the standard Ever-power coupling line.

Ever-power Gear Couplings

FULL ENGAGEMENT TEETH
The Ever-power equipment coupling has been made with full length tooth engagement with the inherent result of longer lifestyle and improved performance.

OPTIONAL PILOT RINGS
The standard Ever-powercoupling consists of two identical half couplings. Optional precision steel pilot rings are available when more accurate centering of both sleeves is required.

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

Ever-power POWERLIGN
This flangeless design transmits identical torques as the typical Ever-power Coupling. Having a smaller sized outside diameter, nevertheless, it is more compact, lighter, and can run at better speeds. This alternative may be chosen for applications where space is bound.

SERIES H Features & Benefits

Higher Misalignment Capability
Sizes 1-7 compensate for ±1 1/2° static angular misalignment per equipment mesh.
Minimizing operating misalignment will increase the life of the coupling. Make reference to the Installation and Alignment Guidelines for alignment recommendations.
Larger Bore Capabilities permit the most economical size selection for shafts up to 10 5/8″.
Higher Torque Ratings due to bigger tooth pitch diameters than additional couplings.
Versatility in that Series H’s are interchangeable by half coupling with competitive coupling designs.
1 1/2° Curved-Face Teeth are a prime feature of the Series H coupling, sizes 1-7. The crowned hub teeth are a 20° full-depth involute tooth form with flank, suggestion, and root curvature. When
used with the straight confronted 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 Grade 5 flange bolts to assure a long-long lasting flange to flange and fastener fit. Exposed bolt flanges are
standard. Shrouded bolt flanges could be provided through size 5. Size #5 1/2 and bigger couplings are only available with uncovered bolt flanges.

LUBRICATION
Each sleeve flange is supplied 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 certainly 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 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.
