NB's GM Slide Bush series features an outer cylinder "load section" made of hardened steel and a "ball return section" made of resin. The two sections are formed together as one unit resulting in an overall weight reduction of 3050when compared to our traditional SM Slide Bush, while maintaining equivalent accuracies and capacities. The Double- wide/Flange Double-wide products have been added to meet the needs of wide variety of application requirements. This new generation Slide Bush will respond to the demands of "low-cost" as well as broaden the application scope of Slide Bush.

STRUCTURE AND FEATURES

NB's GM Slide Bush consists of an outer cylinder casin is steel combined with resin and is formed by precision

g, steel balls, and ball retainer. The outer cylinder casing grinding processes.

Lightweight The GM Slide Bush makes efficient use of resin components making it possible to achieve an overall weight reduction of 3050when compared with the SM Slide Bush. Compact Size The GM-W Slide Bush is shorter in overall length when compared with the SM-W Slide Bush, while maintaining equivalent rated loads. This allows for full use of installation space and stroke. Low Noise Design The ball return section is configured completely in resin material, which provides for low noise operation.

Smooth Movement, High Acceleration/Deceleration Support The GM Slide Bush provides smooth movement under high acceleration/deceleration motion through the accurately lined-up circulation of the balls, a lightweight structure. Product Configurations The GM Slide Bush series is now available in three main types: Single, Double-Wide, and Double-Wide with flange. Each type is available for shaft diameters ranging from 6mm through 30mm. The Double-Wide Flange type may be provided with either Round, Square, or Two Side Cut flanges. Seal An optional integral resin seal is also available.
