Smiths Interconnect launches high-power connectors for demanding defence applications HBB circular connector series now available in the five-pole version


Smiths Interconnect, a leading provider of technically differentiated electronic components, subsystems, microwave, optical and radio frequency products announces today the launch of its HBB five-pole connector in addition to the already existing single-pole version. The new five-pole is an expansion on the existing HBB


platform. The new configuration consists of the existing size 21 shell but contains five poles, each with size eight contacts as well as two interlock pins. This means that in a very tight space, the customer can run five power lines which


increases the connectors’ flexibility and offers the ability to run redundant lines as required. As the five-pole is able to handle five different lines, it is ideal for combat vehicles both


ground and air as it can carry power to various different areas on the vehicle. Looking forward, connectors with these capabilities will be increasingly in demand. “We’re starting to see more hybrid fighting vehicles, and soon we will see all-electric,”


explains Mark Kelleher, Vice President and General Manager of the Connector Business Unit at Smiths Interconnect, “these connectors will be needed for all the ancillary equipment as well as the drive train itself.” The HBB five-pole is also ideal in wider applications within defence, such as missile


launcher platforms and ground radar installations, where the requirements for robust high-power interconnectivity are ever-growing.

InnoTrans 2022 At the InnoTrans 2022 international exhibition for transport technology (20-23 September, Berlin), NSK will showcase a full suite of bearing solutions for axleboxes, traction motors and gearbox applications. The company is accelerating its active engagement with European rail OEMs, particularly in the high-speed passenger segment, and will use InnoTrans to highlight its product innovation, performance and quality at Booth 260 in Hall 20. Among several products in the spotlight will be NSK’s axlebox bearing solutions.


The company has already enjoyed good success on high-speed passenger rail transport systems both in France and the UK, demonstrating reliability, long service life and safety with its RCT sealed-clean tapered roller bearings. NSK’s RCT bearings are highly integrated with surrounding components and incorporate


advanced sealing solutions to ensure durability and optimal performance. Notably, these innovative bearings demonstrate the ability to accommodate complex load conditions, including high shock loads, static and dynamic radial loads, plus axial loads. Elsewhere on the 40m² booth, NSK will present its solutions for traction motors. The key


to reliable AC traction motor bearing operation is in the insulation. If high-voltage current is conducted through the bearing it can cause electrolytic corrosion on the bearing raceway and rolling element contacting surfaces that will result in premature bearing failure. NSK offers a number of alternative designs for insulated bearings to overcome this phenomena, including cylindrical roller bearings and deep groove ball bearings featuring outer rings that are plasma-sprayed with an optimised alumina-based, ceramic coating. This insulating barrier layer, which exhibits high mechanical strength and can handle high loads, increases reliability by preventing any opportunity for electrolytic corrosion. NSK’s ceramic-coating process is proven daily on Japan’s Shinkansen (or Bullet) latest generation high-speed, passenger trains. The most recent innovation for traction motors is NSK’s hybrid deep groove ball


bearings, which incorporate ceramic balls as the rolling elements for applications where first-class electrical insulation is necessary and/or high speeds are required. Withstanding the same load capacity as standard steel bearings, NSK’s hybrid deep groove ball bearings reduce friction levels and generate less centrifugal force which both contribute to extending service life. Maintenance cost can be reduced due to increased grease life. A further solution available from NSK in this area is PPS-insulated bearings. Glass-


fibre reinforced, polyphenylene sulphide (PPS) resin serves as an insulating coating on the external diameter and side-face surfaces of the bearing outer ring to guard against electrolytic corrosion. While the physical properties of PPS are slightly reduced when compared to ceramic, the resin material is more economical, it is ideal for new generations of conventional passenger trains equipped with AC traction motors.


NSK Europe u www.nskeurope.com Take the effort out of fitting your


linear bearings The innovative THK LMHB linear bearing takes the effort out of assembly, with a straightforward press fit design. Snap rings and stop plates are no longer required, as the nut can simply be pressed into the housing. This facilitates quick and easy assembly, reducing time spent on maintenance and boosting productivity. The LMHB also helps reduce the chance of errors occurring during the fitting process, extending the life of machinery. Another pioneering feature of the THK LMHB linear


bearing is its unique curved metal plates which provide a spring effect. This minimises clearance between the rolling elements and the shaft, facilitating smooth, silent linear motion in a wide range of applications. As the LMHB Conforms to ISO 10285 Series 1, existing users of this bush dimension


standard can now benefit from THK technology and the LMHB’s simple drop in interchangeability.

Brammer Buck & Hickman launches new


Bore and Keyway Machining Service Buck & Hickman, the UK’s leading supplier of industrial maintenance, repair and overhaul (MRO) products and services, has launched a new fast and flexible Bore and Keyway Machining Service.


This latest addition to the company’s range of engineering services has seen new bore,


keyway and grubscrew machinery installed, operated by experienced in-house engineers. Now, Brammer Buck & Hickman can rework products to suit customers’ specific requirements and within a short time frame.


The new Bore and Keyway Machining Service encompasses horizontal and vertical


adaptations. The service that is expected to have the greatest demand is machining customer bore and keyways into pilot bored products such as sprockets and couplings. Sprockets are stocked either pre-bored to receive a taper lock bush, or as pilot bored versions that can be machined with multiple bore sizes. In addition, a bespoke service is offered enabling modification to off the shelf products.


Darren Smart, Category Director - MRO at Brammer Buck & Hickman, commented:


“Whilst we have been providing a basic Bore and Keyway Machining Service to customers, up until now this has been outsourced. By investing in state-of-the-art machinery, and staff training, we are delighted to bring this service in-house, for a far more flexible service and a considerably faster turnaround. We can now meet customers’ bespoke requirements and specific tolerances, regardless of whether it is non-standard or has a slightly different fit.”


The new Bore and Keyway Machining Service joins Brammer Buck & Hickman’s range


of engineering services which include specialist workshop, gearbox repair and other engineering services geared towards saving customers money.


Brammer Buck & Hickman is part of the Rubix group, Europe’s largest supplier of industrial MRO products and services.
