Underground Mine Structures

A specialized design combines an external cylinder with a cylindrical raceway and balls that are incorporated in the retainer, making rotary and linear motion in the axial direction possible simultaneously with rotational motion. Small Rolling Frictional Resistance Incorporating a ball with high accuracy into the precisely polished external cylinder results in small rolling frictional resistance and extremely smooth rolling motion together with reciprocal motion. Low Inertia Since the retainer has high rigidity and is lightweight, it has low motion inertia, making it suitable for rolling motion and reciprocal motion in highspeed operations. A Variety of Models Standard and heavy load models are available, each with different load ratings, and each offered with or without seals. It is easy to choose the right product based on the specifications of your machine or device.

Hole Jewel contains a series of components that are chiefly applied as supporting bearings to the rotational systems of various accurate chronographs, auto-memorizing apparatus, precise instruments (micrometer, dial indicator) and other apparatus. Main types: Plane straight/olive holed bearing, single-cup plane straight/olive holed bearing, double-cups plane straight/olive holed bearing, raised olive holed bearing, and single-cup raised olive holed bearing, etc. ■Material Synthetic CZ/KY sapphire, ruby, single crystal α-Al2O3, natural agate, spinel, ceramic, etc.

Slides steel. Ball cages steel. Balls, steel. Version Slides electro zincplated. Ball cages, electro zincplated. Balls hardened. Note for ordering Sold in pairs. Note On telescopic slides with partial extension both sides, the travel is less than the installed length. Latches in open position on both sides. The dynamic load capacity of the telescopic slides indicates the maximum load rating of a vertically mounted slide pair when the entire extension length is used. The load capacity specified is calculated with a slide spacing of 450 mm and is based on the maximum value with 50,000 cycles. The load capacity is ca. 75% lower by horizontal mounting. The head height of the fastening screws should not exceed 2.5 mm otherwise there is a risk of collision with other parts of the slide. Advantages Pulls out in both directions Latches in open position on both sides Light running
