Linear Bearing/
LM L
Linear Motion bearings manufactured at low cost, are used in limitless journeys or used to work in columns. As the loading ball contacts the shaft at a certain point, the bearing application loading capacity is quite small. With balls rotating with quite small friction resistance, high-precise level movement can be obtained. Linear bearings are widely used in precise equipment such as electronic equipment, pull measuring machines, materialization 3-D measuring equipment, etc; and slip parts of industrial machines such as multi-shaft machines, punching machines, tool grinders, auto steam cutting machines, printers, card selection machine,food packing machine and so on.
