The new caged ball SHS LM Guide, which has become a global standard, achieves exceptionally high speed, low noise, maintenance free operation.
Linear actuator covers 100mm to 2700mm
THK has released details of its adaptable GL linear actuator range, designed to provide cost effective linear motion even for high speed applications of up to 3000mm per second.
The SCR is essentially constructed from four THK LM guides, in two parallel sets, mounted perpendicular to each other to form a cross.
The fully integrated unit guarantees smooth consistent motion at high speeds, is extremely accurate, typically to within 2um in every 100mm of travel, and provides an extremely stable platform on which to construct linear motion systems.
The cross rail structure enables the guideway to make complex planar movements, while use of THK Caged Ball technology ensures equal load ratings on each guide rail in the radial, reverse radial and lateral directions.
Caged Ball technology also means that each guide section in the new SCR produces less noise, has far smoother motion, even when used in vertical mounting, and has a longer service life than competing guides.
Using the SCR, machine builders and OEMs can now specify one complete unit, as opposed to separate guides, rails and mounting blocks.
In addition to saving design and specification time, the new product also significantly reduces assembly time and eliminates potential problems of misalignment in the x and y axes.
The SCR can be used in any mounting orientation and is available in several models: the SCR 25, 30, 35, 45 and 65 with heights ranging from 70 to 180mm.
The model widths vary from 88 to 226mm and the lengths from 109 to 226mm.
Precision, super precision and ultra precision accuracy grades of the cross Caged Ball LM SCR type are available, with each being supplied with a choice of contamination protection devices such as end seals, double seals and scrapers.
Typical applications include inspection devices, printed circuit board assembly machines and x and y axes control of horizontal machining centres.
