Warner Linear develops new actuator range

Finding components that perfectly suit the needs of an application can often be frustrating. Design engineers will often have to compromise their original design to some degree in order to match the components that are available. However, when a manufacturer of ramps for wheelchair accessible vehicles needed to find a linear actuator with a small footprint that could manually retract if required, Warner Linear was able to design a new product range that perfectly met all of its needs. A leading manufacturer of ramps for wheelchair accessible vehicles was looking for a replacement linear actuator product to fold and unfold its ramps. Due to the restricted space available it was not possible to use a parallel motor design; rather, an inline design had to be used. The previous actuator specified by the manufacturer required tremendous force to manually retract in the event of a power failure. The OEM was looking to improve the design of the ramp so needed to source a component better suited to the application. Warner Linear, part of Altra Industrial Motion, was approached to see if its engineers could recommend a solution that would fit within the restricted footprint whilst offering the performance criteria demanded. At the time there were no products within Warner’s range that could meet all of the design requirements. However, rather than give up, Warner worked closely with the customer to design the I-Track actuator – a unique inline design with a release clutch and extremely narrow footprint. Eric Volant, Product & Business development Manager for Warner Linear, comments: “We pride ourselves on offering our customers flexibility and a customised service....

Global Bearings celebrates 15 years of successful Partnership

In 2011 Global Bearings and Transmission Limited of Bromsgrove were very proud to announce becoming Bosch Rexroth official sole UK linear motion sales partner. This year, Global Bearings and Transmission Limited, celebrates 15 years in this partnership with Bosch Rexroth, further cementing an already, successful partnership. Bosch Rexroth is recognised for its high quality linear motion products, ranging from linear modules and actuators, profiled rail guides, ball screw assemblies, to a multitude of ball bushings and shafts. Global Bearings offer 25 years of experience in the linear motion marketplace and provides accurate alternatives to THK, SKF,INA, amongst other leading brands, which benefit from the in-built interchangeability of individual components within the Bosch Rexroth range of products. Gordon Reeves, Linear sales manager of Global Bearings and Transmission Limited explains, “It has been a pleasure to do business with Bosch Rexroth over the last 15 years, and we look forward to the next 15 years continued success!” and concluded; “With our highest ever stock levels in our Midlands warehouse, and a new computer link direct with Bosch Rexroth UK and Germany, we can now offer an even faster and efficient service to our customers.” Global Bearings’ customers can benefit from a full manufacturer’s warranty and joint technical expertise when purchasing through an authorised sales partner of Bosch Rexroth. Together with Bosch Rexroth, Global Bearings Limited, can assist with, and supply products, from inception and design stages right through to component replacement requirements for future service and repair operations....

Integrated, Open Frame, XY Linear-Motor Stage with High Dynamic Performance

Aerotech’s PlanarDLA integrated, open-frame stages have high dynamics and exceptional geometric performance in a low-profile package. These stages are essential for applications ranging from two-sided LED wafer processing where high-dynamics and micrometer-level straightness are required, to quasi-static optical metrology where high-accuracy and precise geometric performance are necessary. The PlanarDLA XY design is optimized for applications where straightness and flatness of motion are critical. High-precision roller bearings, precision-machined surfaces, and noncontact direct-drive linear motors driving through the axes’ center-of-stiffness result in a positioning stage with straightness to ±0.5 µm and flatness to ±1.25 µm. Optimized for high-dynamic applications Structural elements are optimized for high dynamics and high stiffness for the most demanding dynamic applications. The PlanarDLA achieves high servo bandwidths while at the same time maximizing the clear aperture available and keeping the overall height to a minimum. The PlanarDLA enables high-throughput, high-accuracy processing with 2 m/s velocities and 2 g accelerations, resulting in superior process yield and a low total cost of ownership. At the heart of the PlanarDLA is Aerotech’s proprietary direct-drive technology. This allows for unmatched performance compared to other competitive screw-based and linear motor designs. Only noncontact, direct-drive technology offers high speed and accurate positioning coupled with maintenance-free operation and long service life. Speeds to 2 m/s and accelerations to 2 g PlanarDLA stages are available with one or two motors per axis allowing optimization of each axis for the specific application and process. With two motors, the resulting drive force acts through the centres of friction and stiffness for superior geometric performance and accuracy, while one motor per axis is the economical choice if high-throughput...

Acorn acknowledged as a leading THK Specialist

THK the world’s leading manufacturer of linear motion products has awarded Acorn Industrial Services Ltd their prestigious ‘Class A’ distributorship status, recognising Acorn as one of their premier distributors within Europe. The award marks a significant achievement for Acorn and is testament to their professionalism and authority in the field of linear motion. Simon Gillingham, Acorn’s Linear Product Specialist explains, “Being awarded a Class A distributorship from THK is a substantial achievement for Acorn, it acknowledges our commitment to the THK brand and recognises our ability to respond promptly to enquiries, provide the highest level of technical expertise and solutions for our customers and supply orders quickly and accurately.” Acorn’s specialist linear division has grown by over 225% in the last five years and holds over £500,000 worth of THK linear stock – making it the largest stockist of THK linear motion products in the UK. A large part of the company’s success is attributed to their strong company ethos of providing customers with a full linear technical service and ensuring customers receive the right linear solutions for their application.  ...

drylin belt drive takes centre stage

Linear motion specialist igus has developed its latest linear belt drive for use in the entertainment and theatre industry. The drylin toothed belt axis is ideal for the movement of stage systems or prop adjustments, offering a range of possible applications. Due to the use of iglidur polymer plain bearing materials in all moving parts, the drylin toothed belt axis is self-lubricating and maintenance-free, ensuring quiet running while minimising background noise. Ideal for camera movements, the toothed belt axis helps ensure quick and smooth positioning. The hard-anodised aluminium profile and carriage plate, make it lightweight and provides rigid support for camera and lighting systems.   www.igus.co.uk    ...
