SKF launches big range of parts for machine tools
A complete package of products, aimed specifically at machine tool builders and users, has been unveiled by SKF Engineering Products Limited.
In order to obtain such accuracy, precision ball screws must be supported with bearings of special design to provide optimum axial run-out and rigidity characteristics.
The high precision ball screws now offered by SKF Engineering Products rely on the company's range of ball screw support bearings, which give high dynamic and static load ratings, high speed capability, superior axial rigidity and extreme running accuracy, especially in an axial direction.
The precision ball screws therefore easily meet the operating demands of a wide range of machine tool applications, including grinding machines, machining centres, lathes, drilling equipment, milling machines and EDM machines.
They will typically be used for high-speed spindles to increase tool performance, accuracy, and service life.
As well as supplying four different versions of the high precision ball screws, SKF EPL also offers complete screw assemblies with machined ends, to customer drawings, or screw shaft cut-to-length, with the nut mounted on a sleeve.
Nuts are available preloaded or with axial play, with the preloaded version ideal for applications where accuracy of positioning under load is important. Request a free brochure from SKF UK ...
