Multi-Axis Linear Positioning System High Precision Ball Screw Rail Guide

The dust-proof device can protect the quality of block, in the presence of dust and iron could avoid abnormal wear inside the slider, shorten the service life .

Dust-proof products are for the existence of dust, wood chips, iron and other impurities in the bad environment. The product configuration of a high degree of production accessories.

Linear guides are mainly used in Turning lathe,Boring Machine,Grinding Machine, grinding machines, lathes, industrial automation machines, etc.

The first modern recorded patent on ball bearings was awarded to Philip Vaughan, a British inventor and ironmaster who created the first design for a ball bearing in Carmarthen in 1794. His was the first modern ball-bearing design, with the ball running along a groove in the axle assembly.^[8]

Bearings have played a pivotal role in the nascent Industrial Revolution, allowing the new industrial machinery to operate efficiently. For example, they saw use for holding wheel and axle to greatly reduce friction over that of dragging an object by making the friction act over a shorter distance as the wheel turned.

The first plain and rolling-element bearings were wood closely followed by bronze. Over their history bearings have been made of many materials including ceramic, sapphire, glass, steel, bronze, other metals and plastic (e.g., nylon, polyoxymethylene, polytetrafluoroethylene, and UHMWPE) which are all used today.

Watch makers produce "jeweled" watches using sapphire plain bearings to reduce friction thus allowing more precise time keeping.

Even basic materials can have good durability. As examples, wooden bearings can still be seen today in old clocks or in water mills where the water provides cooling and lubrication.
