Recirculating Guides Available on Fast Lead Times

Schaeffler has announced that it is now offering its RUS and PR linear recirculating roller guidance systems to UK customers on fast lead times. John Loonam, linear product specialist at Schaeffler, said: 'Although the RUS and PR linear recirculating roller guidance systems have been part of our range for many years, many UK customers, particularly machine builders and machine tool retrofitters, still have a requirement for these types of linear guides.

'Fortunately, Schaeffler UK holds a good stock of these units available on fast lead times - typically one to two months,' he added. Linear recirculating roller guidance systems comprise INA linear recirculating roller bearings, with guideways and adapters. The units can be used as locating/locating or locating/non-locating bearings. In a closed arrangement, the bearings can support loads from all directions and moments about all axes. The RUS and PR versions within the range are said to be popular with machine tool retrofitters and machine builders as these units offer very high load carrying capacities while requiring little installation space.

Loonam continued: 'The units also provide extremely high rigidity under preload. 'The RUS and PR units come with adjusting gibs, which facilitate mounting and provide uniform distribution of the preload over the entire length of the linear recirculating roller bearing, enabling the preload to be set very easily,' he said. The RUS..KS version offers smooth, low-noise operation thanks to the seals on the end faces. This unit can be lubricated through the end piece and can operate in temperatures from -30C to +90C. The PR model is a full-complement cylindrical roller set and is suitable for use in high operating temperatures and at high speeds and high accelerations. Of all-metal construction, the PR can operate in temperatures from - 40C to +120C.

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.
