Bedford, MA, April 19, 2004 -- Steinmeyer, Inc. has expanded its Quiet Ball Screw product line with eight (8) new sizes. These will be featured at SEMICON WEST in Booth 5536. With diameters now ranging from 5 to 20 millimeters, the new sizes provide greater flexibility in applying precision ball screws that have been specifically engineered for smooth super-quiet motion. Ball screw noise is virtually eliminated because instead of metal tubes the nut utilizes end cap ball returns manufactured from plastic.
When the Series 24xx Quiet Ball Screw was first introduced in 2002, three sizes were offered: 12 x 10, 16 x 10 and 16 x 30 (diameter x pitch). Eight new sizes were recently added: 5 x 2 (5 mm diameter with 2 mm pitch) 8 x 2 10 x 4 12 x 516 x 1616 x 2016 x 3220 x 10Quiet Ball Screws are available with or without backlash, and in a choice of two accuracy grades – T5 (ground thread, series 2426) and T7 (rolled thread, series 2446). Combination wipers are standard. And, several sizes are compatible with the latest DIN 69051 ball screw standard. For pitches greater than 5 millimeters, the Series 24xx ball screw utilizes a dual start thread profile that provides substantially higher load carrying capacity compared to single start screws.
Because the nominal diameters are relatively small, this new screw exhibits low inertia, a distinct advantage for high speed applications. And, by eliminating external return tubes, the nut body is considerably smaller. To protect against contamination, the ball nut is fitted with the exclusive Steinmeyer Combination Wiper system consisting of labyrinth seals and felt wipers. The felt, saturated with oil or liquid grease, enables long - term lubrication as well as superior wiping action.
Should the application require high vacuum compatibility, the Series 24xx ball screw can be assembled using end caps manufactured from Teflon™, as an option.Applications for the new Series 24xx Quiet Ball Screw include semiconductor production machines, inspection equipment, medical devices, pick and place machines, robotic mechanisms and automation equipment.For additional information call George Jaffe at 1-800-297-6403 or visit www.steinmeyer.com .Schneeberger Inc. is the exclusive North American distributor of Steinmeyer Ball Screws.
