Hepcomotion Offers Corrosion-Resistant Ball Guides

Hepcomotion has added a corrosion-resistant model to its LBG range of ball guides, opening up the market for this product in clean rooms where previously stainless steel was the only suitable option. The hard chrome alternative is available for all rails and bearing blocks in this linear ball guide product programme. It provides a good degree of corrosion-resistance for application where moisture or contaminants could cause surface pitting.

The company said the LBG range offers high quality, good rigidity and accuracy. Its basis is a four-row angular contact ball track that is said to have numerous benefits. These include low friction and reduced differential slip, high load-carrying capacity in four directions and installation compliance. It also compensates for minor errors on the mounting surface without compromising performance, Hepcomotion added. A felt wiper within the bearing block aids lubrication, maintaining a positive oil film on the bearing contact surfaces.

Extended life and increased maintenance intervals are achieved by having the correct amount of lubrication at the contact faces. LBG corrosion-resistant rails are supplied up to 4m in length and in matched sets to ensure that even with the addition of the hard chrome coating, the pre-load of the block onto the rail is consistent. A stock range is available to cover the majority of automation requirements. However, a wider combination of pre-loads and grades can be supplied to suit the specific needs of individual applications.

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.
