PRT Enables Higher Load Capacities



PBC Linear has announced the release of its Profile Rail Technology (PRT), which will consist of application-specific caged and non-caged runner blocks with a lubrication system. The company said the technology offers longer life, ability for higher load capacities, and corrosion-resistant chrome rail finishing for tolerating harsh environments. Backed by a reservoir lubrication system to ensure longer life and smooth, quiet operation, PRT's runner blocks aim to provide reliable linear motion without further lubrication.

As the ball bearings circulate, they are lubricated by end-cap reservoirs, providing a protective lubrication film in the ball tracks, facilitating a long-lasting system. The new caged-type runner blocks have additional built-in oil reservoirs at every cage ball pocket, which extends or eliminates the time between lubrication cycles. Caged runner blocks also provide up to 19 per cent more load capacity and reduce noise and vibration by 84 per cent more than competing technologies.

To keep dirt out and extend life, all PBC linear runner blocks incorporate a standard double-row sealing system. Runner blocks are available in wide and narrow, low and high combinations, in addition to short, long, and extra-long configurations. The rails and runner blocks are outfitted with corrosion-resistant black oxide, chrome or black chrome rail finishes.

Biasi Develops ActivA Unique Boiler Range Biasi UK has developed ActivA, a new range of high efficiency A rated condensing boilers boasting a unique heat exchanger. The launch of ActivA is further testimony to the company's commitment to strengthen its position in the UK domestic gas boiler market. At the heart of ActivA is a newly developed pre-mix condensing heat exchanger that is manufactured in a corrosion resistant, pressure moulded aluminium. Its sectional construction means it can be easily adjusted for different boiler outputs and its 'multipass' design ensures very low resistance for both combustion and water passage. This unique heat exchanger carries a five year guarantee. Designed to provide outstanding heating performance at an affordable price for almost all types of domestic properties, the compact range boasts some of the smallest boilers available - at just 700mm high x 400 wide and only 290mm deep - thereby allowing installation in cupboards.

Han® HC 250 high current contact

A Powerful Solution HARTING has developed the new Han® HC 250high current connector as a powerful interface that impresses by requiring little space, transmitting high current intensities and allowing flexible configuration of the number of poles. The HC 250 one-pole crimp module can be connected in various frame geometries to produce the required number of poles in a compact space – and in the existing Han® HPR housing. Technical details: - Rated current 250 A at a rated voltage of 2000 V - Termination cross-sections are: 35 mm2, 50 mm2 and 70 mm2 - Maximum four-pole interfaces in a size 24 B HPR housing, making it particularly suitable for motor connections - High quality plastic with good smoke and inflammability levels - Removal tool for simple installation and removal of the contacts and inserts - Confusion of a number of interfaces is reliably prevented by multiple coding options for the individual inserts The requirements in the railway industry are changing, as
