Rugged Linear Bearings Suit Use in Automation

Maintenance-free, lubricant-free and suitable for extreme environments, Drylin linear bearings from Igus operate on glide pads, unlike the more common re-circulating ball bearing systems. The Igus Iglidur J, J 200 and X materials are suitable for most linear applications due to their positive wear and friction properties; being made of standard Iglidur materials means that they are also lubrication free, maintenance free, insensitive to dirt and have a low coefficient of friction.

In contrast to re-circulating ball bearings, the Igus Drylin bearings do not depend on the travel length and hence do not pose any restrictions on the minimum stroke length. There are four main types of Drylin linear bearing, the Drylin T, N, W and R. Drylin T linear guide systems were developed for applications in automation and handling systems. The design objective was a rugged linear guide for application in the most diverse and extreme environments. It has six gliding pads made of Iglidur J that are positioned opposite each other in pairs and make up three bearing guides.

The bearings are all continuously adjustable even once fitted. Drylin N is a low-profile guide system that offers low profiles in various widths and at a low installation height. The material used and the unique design make Drylin N a cost-efficient, light weight and flexible guide system. Drylin W linear guides constitute a cost-efficient pre-assembled system. The design of the linear guide allows for high flexibility in assembly and a simple installation using single or double rails. They are well-suited for applications that require good torque resistance, anti-corrosion properties, and a flexible linear guide system.

Drylin W systems are also frequently found in sliding camera applications. The final variant, the Drylin R linear plain bearings are based on wear-resistant polymers developed specifically for the linear technology. The dimensions are compatible with standard ball bearings, and the special geometry guarantees ruggedness even in extreme environments.

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.
