Interchanged linear guides are divided into THK series linear guides and HIWIN series linear guides.it’s easy to assemble and repair.
The important is that interchanging linear guides have high cost-effective, assemble on the same size and high precision, high reliability CNC machine or other general equipment or device.
Interchanging Linear guides are mainly used in general requirements, such as lathes, woodworking machines, handling machines, transport devices, industrial automation machines, etc.

Two-piece plain bearings, known as full bearings in industrial machinery,[11] are commonly used for larger diameters, such as crankshaft bearings. The two halves are called shells.[12] There are various systems used to keep the shells located. The most common method is a tab on the parting line edge that correlates with a notch in the housing to prevent axial movement after installation. For large, thick shells a button stop or dowel pin is used. The button stop is screwed to the housing, while the dowel pin keys the two shells together. Another less common method uses a dowel pin that keys the shell to the housing through a hole or slot in the shell.[13]
The distance from one parting edge to the other is slightly larger than the corresponding distance in the housing so that a light amount of pressure is required to install the bearing. This keeps the bearing in place as the two halves of the housing are installed. Finally, the shell's circumference is also slightly larger than the housing circumference so that when the two halves are bolted together the bearing crushes slightly. This creates a large amount of radial force around the entire bearing, which keeps it from spinning. It also forms a good interface for heat to travel out of the bearings into the housing
