Instruction

Linear ball bearings are commonly used in low-cost linear motion systems. This product consists of a cylinder-shaped outer ring, multi-row steel ball, and a cage. It can make a reciprocating motion on a shaft. Multi-row steel ball and low friction allows the bearing for mechanical equipment to be moved easily and lightly. In addition, the industrial bearing is durable. It also gives convenience for maintenance and replacement.

Allowing for different shapes, the linear ball bearing can be divided into the straight tubular type, open type, and the flanged type. The linear motion product is widely applied in industries including the electronic equipment, food machinery, packaging machinery, CNC machine tools, and the automotive lamps.
