Aftermarket gearbox replacement
SPX Cooling Technologies, Inc. introduces a new model to its expanding line of gearboxes, the M Series Geareducer. e expansion, the M1311 model, is a direct drop-in, aftermarket replacement for Amarillo 1311 gearboxes, eliminating the need for adaption materials. e entire M Series Geareducer line is designed and manufactured to directly and easily replace other OEM gearboxes in eld-erected cooling towers. e new M1311 model Geareducer gear drive incorporates the same di erentiating features as the Marley Series 32.2 Geareducer; including the Inpro input shaft oil seal to eliminate grooving and extend life. It is available in ratios from 7.89 to 14.64. e gear drive’s primary function is to reduce the speed of the electric motor to optimize fan performance. e Marley Geareducer gear drive goes beyond the American Gear Manufacturers Association (AGMA) requirements to maximize air movement through the cooling tower and to minimize maintenance. It provides primary support to the fan, anchors it against lateral movement, withstands shock loads at start-up and during speed changes, and minimizes power transmission losses, as well as sound generation. e M Series features gears of high-strength, case-hardened
alloy steel machined to AGMA Quality Class 9 and above.
It is designed to t into non-Marley cooling towers for easy replacement and has heavy-duty double-row interstage bearings for 100,000 hours of life or more. e M Series
gear drive operates without need for add-on oil pumps, oil lters, or oil coolers. It runs with two-stage gear reduction for e cient power transmission; external cooling ns maximize the surface area for cooler operation.

Heavy duty encoders for severe environmental conditions
POSITAL’s heavy-duty IXARC incremental and absolute rotary encoders are built to stand up to extreme environmental conditions. Based on a housing design with a 25-year track record of surviving tough conditions, these devices are suitable for marine vessels, o -shore facilities, mines, cranes, wind turbines, and other challenging locations. ese sensors feature rugged impact-resistant Type 316L stainless-steel or aluminum housings with seals rated to IP67. Other features include bearings that
can stand up to 250 N axial, 350 N radial mechanical shaft loads and the ability to stand up to high shock (200g) and vibration (20g) impact. A special shaft-lock mechanism protects the internal components of the encoder from damage due to extreme thrust loads on the shaft. An optional mechanical overspeed switch provides an additional level of safety for equipment and operators by sending a warning signal to a motor control if the rotational speed of the shaft exceeds a pre-set limit. e operating temperature range for the heavy-duty IXARC encoders is -40°
to 80°C. e heavy-duty IXARC encoders are available in a wide variety of con gurations. Incremental versions have resolutions (pulses per revolution) of up to 2500 PPR, while absolute versions are available with 16-bit resolution (.005°). Multi-turn variants of the absolute encoders have measurement ranges as high as 16,384 revolutions (14 bit). Other resolutions are also available for both incremental and absolute encoders. Incremental variants are available with Push-Pull (HTL) or RS422 (TTL) communications interfaces, while absolute models can be provided with either CANopen or SSI interfaces. Dual-function models are available that provide both incremental and absolute outputs.

Diamond-coated insert grades o er high- performance aluminum drilling
Sandvik Coromant has unveiled its CoroDrill 880 CVD diamond- coated insert grades, GCN124 and GCN134. e super-hard properties of the diamond coating provide long tool life and combine with innovative chip breaker and geometry designs
to guarantee high performance when drilling materials such as aluminum. GCN124 and GCN134 diamond-coated insert grades are designed to o er a low cost per hole in most ISO N materials thanks to long lasting insert tool life. Increased productivity could be gained from elevated cutting data and less machine downtime from fewer insert changes. Further advantages include easy handling in production due to the reliability and long life
of the inserts as well as enhanced surface nish inside the hole, which results from the ability to resist BUE and smearing e ects. Reduced insert consumption also helps lower stock levels and environmental impact. GCN124 and GCN134 complement the existing H13A, uncoated insert from Sandvik Coromant, which is recommended in applications involving shorter production runs and/or di cult interrupted cuts. e standard CoroDrill 880 range features indexable insert drills from 12 to 84mm (0.472–3.307")
in diameter, with drill lengths of 2, 3, 4, and 5 × D. Sandvik Coromant’s Tailor Made o er allows intermediate diameter and length combinations as well as di erent connection types and sizes such as HSK, Coromant Capto, or cylindrical shank. Another Tailor Made option includes customized step and chamfer drill designs for speci c components.

Expanded guide describing custom components, engineering process
Bal Seal Engineering, Inc. has published an expanded guide describing the form and function of its custom-engineered seals, springs, and electrical contacts,
as well as the bene ts of its engineering process. e 12-page guide, titled Sealing, Connecting, Conducting, and EMI/RFI Shielding Solutions, uses photorealistic application images and descriptive
insets to give readers a detailed look at where and how Bal Seal spring-energized seals, Bal Spring canted coil springs,
and Bal Contact electrical contacts work in aerospace and defense, analytical, automotive, energy, and medical equipment. A graph in the guide’s
spring technology section compares the de ection of canted coil springs with other seal energizer types, including V-springs, ribbon springs, and o-rings. e guide also provides information about the company’s collaborative engineering approach, which forges partnerships
with OEMs and tier suppliers who want to make their products faster, stronger, lighter, or more functional.

High yields and increased performance
Senvion launched its new products, the 3.7M144 EBC and 3.6M118 NES turbines, which are especially well suited for low and high wind sites respectively and feature the Senvion Next Electrical System (NES) to meet the grid requirements in
all Senvion target markets. e 3.6M118 features an optimized rotor design for very high yields and is mounted on a steel tower with a standard hub height of 91 meters, with project speci c hub heights also available. e 3.7M144 is designed
to be one of the quietest systems in its class with its strengths at low wind speeds due to aerodynamically optimized blades and serrations at the blade edges. With
a nominal output of 3,700 kilowatts and
a larger rotor, the new turbine leads to
a yearly energy yield 6.7% higher than
its sister models. e Next Electrical System (NES) features a gearbox-based concept with an asynchronous generator and a fully rated converter that permits stable grid feed-in and meets the grid requirements in Senvion’s markets. Senvion | www.senvion.com
