DescriptionThis item is manufactured with nickel plating material for durable and long lasting use. Excellent workmanship makes it suitable for high-end equipment. Universal equipment using. Round linear bearing accessory provides you precision use.Features-Color: Silver. -Material: Carbon steel. -Size: About 4.5x3x1cm/1.77x1.18x0.39 inch. -Linear bearing is a linear motion system produced at low cost, used in conjunction with a cylindrical shaft with an infinite stroke. -Since the bearing ball is in point with the shaft, the use load is small. -The steel ball rotates with very little frictional resistance, so that high-precision and smooth motion can be obtained. -Feature linear bearings are used in conjunction with hardened linear drive shafts. -A system for infinite linear motion. Because the load ball and the quenched drive shaft are in point contact, the allowable load is small, but when moving in a straight line, the friction resistance is small, the accuracy is high, and the movement is fast.
