Linear guides power generating

Paul Boughton

THK, the developer and manufacturer of linear motion technology, has introduced its latest range of linear guides and ballscrews for use in a wide range of applications in the power generating and associated sectors.

In particular, the latest products have been designed to offer exceptionally high levels of positional accuracy, combined with heavy load bearing capacities, fast operation and a long, maintenance-free working life in areas that include gantry and equipment movement systems, training simulators and ancillary equipment for fixed and mobile diesel generating sets.

The latest range of products includes the HBN high-performance ballscrew that, size for size, is capable both of transporting over twice the average dynamic load of competing devices and of producing double the typical maximum nut speed (the DN value). With a dynamic load capacity of up to 997kN and operating speeds of up to 130,000DN, the HBN is especially suitable for applications that demand high-speed precision movement of larger loads, such as the accurate positioning of robotics and automation equipment.

The HBN features THK's proven Caged Ball technology together with a high-speed ball return system that eliminates ball-to-ball contact and ensures that all lubricants are retained; as a result, operation is smooth, silent and virtually maintenance free, minimising frictional losses and helping to cut energy consumption by as much as 33 per cent.

Also being introduced by THK are the latest SNR and SNS linear guides. Both units incorporate Caged Ball technology, giving smooth, high speed and virtual maintenance free operation, with a high level of rigidity to allow exceptionally precise positioning to be achieved. Indeed, so effective is the Caged Ball system that when compared with traditional devices rolling resistance is reduced by up to 90 per cent and noise levels by more than 50 per cent, with corresponding reductions in heat and friction.

Perhaps as importantly, the latest linear motion guides are capable of transporting exceptionally heavy loads, with the SNS in particular being rated up to 5,530kN, are available in six heavy duty models and six ultra heavy duty models.

A range of accessories are available to further enhance the performance of the latest ballscrews and linear motion guides, including THK's unique QZ lubrication system, that gives significantly extended maintenance intervals with reduced usage of lubricants, and contact scrapers for applications where an additional level of contamination control and protection is required.
