1) Different structure
The totally enclosed linear module is to seal the transmission part inside and prevent the dust from falling on the transmission part.
The semi-enclosed linear module has a mouth on both sides. This mouth is open to the mover seat, and the transmission member can be seen through the mouth.
2) The use of different environments
The semi-enclosed linear module is mainly suitable for dust-free working environment. The totally enclosed linear module is used in dusty environment, mainly because the dust will affect the life of the linear module. For example, some dusty environments use semi-closed straight lines. Modules, dust is easy to enter, dust stuck to the screw, if you do not clean up will affect the operation of the screw, but if you often need to remove the cleaning, this is a waste of time, so the general more dust working environment Select a fully enclosed linear module.
3) Different costs
Fully enclosed linear module is relatively high compared to semi-closed, and its profile is also not the same. Semi-closed is a concave shape, full closed is a bit like a mouth shape, just the place of the upper mouth A groove is opened. This groove is used for a movable seat, and then a steel wire belt is placed on the movable seat. It also has a dust cover. It is harder to install the fully enclosed linear module than the semi-closed linear module in terms of assembly. One point, so these are the reasons that indirectly cause higher costs.
In short, which module to purchase is more suitable for the enterprise, depending on the specific working environment and the user's assembly technology level.
