Exhibitor: PRECISION MOTION INDUSTRIES, INC.

Booth No: J302

Characteristic

Characteristics︰SKM series consist of linear guideway unit and ballscrew unit. For saving space, PMI combine the carriage of linear guideway and nut of ballscrew to a integral carriage-nut. The carriage-nut cooperate with the U rail designed for
high rigidity to achieve the high rigidity and high accuracy in the minimal space, especially to saving time of installation. Moreover, the design of two rows with gothic-arch groove and contact angle of 45°can bear four directional loading.
Application︰IC / LSI Manufacturing Machine / Hard Disc Drive / Slide Unit of OA Equipment / Wafer Transfer Equipment
Features︰
1.Ball Chain Design, Smooth Movement︰The U rail and carriage-nut circulating system with the ball chain design which use the strengthened synthetic resin of accessorize and avoid interference between balls to make it more stable during passing the load district. Besides, the ball chain can keep the ball move in line and improve the movement.
2.Low Noise︰The retaining pieces of the carriage-nut can avoids collision between balls then decrease the noise. Non-mutual friction can decrease heat generation and keep the accuracy in the range.
3.High Dust proof, Extend The Maintenance Intervals︰The carriage-nut with the wiper at both ends can reduce grease leakage. Besides, the wiper with a special lips structure can matches the threads that ensures the removal of scraps as well as insulation dust.
4.Four Directional Equal Load︰SKM series are applied two rows with gothic-arch groove and designed to contact angle of 45° which enables it to carry an equal load in radial, reversed radial and lateral directions to suit to any mounting orientation.
5.Saving Space︰Combine the carriage of linear guideway and nut of ballscrew to a carriage-nut, SKM series can achieve
the best use of space.
6.High Rigidity︰Base on the optimal analysis of FEM for the shape of U rail, it has the balance between light weight and
high rigidity.
7.High Accuracy︰The design of two rows with gothic-arch groove and stable manufacturing technology can control the variation by load at the minimum. It can provide the smooth feed with high accuracy.
