Aluminium Rings Provide Very Quiet Operation

Hepcomotion's new ALR aluminium rings are designed to be a cost-effective choice for medium-precision, lightly loaded applications, such as in theatre and film animation. Bishop-Wisecarver Dualvee polymer overmoulded guide wheels with integral studs make a significant contribution to the ring's virtually noiseless operation. They are claimed to run exceptionally smoothly, with little friction or wear on the ring vees.

All metal parts are stainless steel and the shielded wheel bearings are lubricated for life. The ALR rings themselves are machined from high-strength aluminium alloy and anodised to a specification that gives an excellent combination of durability and corrosion resistance. The finish is attractive and provides a good running surface for the Dualvee polymer wheels. Another advantage is that aluminium provides designers with a non-magnetic choice.

ALR rings can be supplied with a special finish, which is engineered to be more corrosion resistant than stainless steel and very durable. It is approved by the US Department of Agriculture for food use. Rings are available in four standard sizes, from 148mm to 300mm in diameter, and these are compatible with the size-two Dualvee wheels. For smaller, lighter applications, sizes one and zero Dualvee wheels can be specified. Special rings can be supplied economically. The choice includes different diameters and thicknesses, rings with internal vees, gear cut rings and rings machined in the form of self-aligning timing belt pulleys.

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.
