New Power Transmission Couplings Last up to 30 Times Longer

The Sure-Flex® brand of elastomeric couplings is a best seller in the US and for very good reason. It provides many performance advantages over other power transmission couplings of this type. Now Sure-Flex® is available from Huco Dynatork whose distribution channels can assure its ex-stock supply throughout Europe.

Sure-Flex® elastomeric couplings are the ideal choice where low cost, high flexibility and vibration dampening are primary concerns. Quick and easy installation is assured as the design has no bolts, gaskets, covers or seals; no special tools are required. Alignment is simply checked with a straight edge placed against the outside of the precision-machine flanges. Characterised by their clean, dependable and quiet performance, these products need neither lubrication nor maintenance as the components are wear-free and the design is immune from the ingress of abrasive dirt and moisture.

Sure-Flex® couplings use a synthetic rubber or Hytrel™ thermoplastic flex element to transmit torque – up to 8.2 kNm – and to accommodate shaft misalignment. Indeed they have exceptional torsional flexibility and their 4-way flexing action absorbs virtually all types of shock, vibration, misalignment and end float. ‘Fatigue test to failure’ results confirm that the Sure-Flex® polymeric flex elements last twice as long as their nearest competitive coupling and up to 30 times longer than the remaining competitive models. As a result these couplings are proving extremely popular in all manner of rotating machinery across a wide spectrum of industry.

Typically Sure-Flex® couplings are found in systems involving pumps, fans, blowers, compressors, mixers, electric motors and conveyors. Flex elements are available in a choice of four materials or compounds and in various shape configurations to suit the application. Spacer, bushed hub and clamping hub designs complete the range, the most popular sizes of which are available from stock.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
