Y-Bearing Units Developed for Food/Drink Industry

SKF has introduced a new generation of Y-bearing units developed to offer an effective solution for the demanding and varied environments in the food and beverage industry. These robust units offer maintenance-free performance and have been designed to withstand a range of operating temperatures, as well as humidity, aggressive fluids, gases and light particulate matter. Suitable for use in conveyors, sorters, sizers, presses, augers, brush washers and all washdown areas, the Food Line Y-bearing units feature SKF's 2RF seal to withstand high-pressure washdowns, as well as other sources of moisture and process contaminants.

As these seals prevent water, detergents and light contaminants from entering the bearing, they eliminate the need for relubrication after washdowns to purge water and contaminants, extending bearing lifecycles considerably and reducing lubricant consumption and maintenance requirements. Hygienically developed, sealed and lubricated for life with NSF-approved SKF food-grade grease, the units enable productivity levels to be optimised and costs to be minimised, while eliminating the risk of contamination. This means that the devices offer consistently reliable service despite the demanding conditions typical of food-production lines, reducing maintenance requirements, lubrication consumption and costs.

The SKF Food Line Y-bearing units will operate for years on a single food-grade grease prefill, saving plants a substantial amount of lubricant and maintenance costs. For example, this can save as much as 78kg of lubricant, as well as over 100 minutes of labour time per weekly maintenance cycle for a plant that relubricates 100 bearing positions over the course of a year. Equally, this keeps excess lubricant out of plant wastewater streams thus preventing it from entering the environment. Lubricant reduction also represents savings in wastewater treatment costs and offers a range of additional benefits, including reduced downtime and maintenance, as well as eliminating the risk of lubrication points being missed.

The new bearing units feature a curved, non-porous surface with no cavities for easier cleaning and reduced risk of bacteria accumulation. They are available in a variety of housing shapes, an extended size range and corrosion-resistant materials, including composites, zinc-coated and stainless-steel designs, as well as stainless-steel or zinc-coated bearing inserts, to meet the requirements of diverse applications. An effective end cover is also available for processes where health and safety regulations demand it.

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.
