The side seal is used in locations on the LM block which are prone to dust entering from surfaces such as the side or bottom. These include vertical, horizontal and inverted mounts.
The inner seal can be located in areas that are severely exposed to dust or cutting chips.
The double seals can be located in areas exposed to significant amounts of dust or cutting chips.
The non-contact metal scraper is used in locations where welding spatter may adhere to the LM Rail.
The Common Seal Types:
UU - With end seal
SS - With end seal + side seal + inner seal
DD - With double seals + side seal + inner seal
ZZ - With end seal + side seal + inner seal + metal scraper
KK - With double seals + side seal + inner seal + metal scraper
LaCS are made to order for locations with adverse environments. The LaCS is non-standard stock item from THK for selected LM Guide models. The LaCS is designed to remove minute foreign materials, found on the LM rail, in various stages and prevents it from entering the LM block with laminated contact structure.
This is due to the fact that the three layers of scrapers have full contact with the LM rail. It also creates low friction due to its oil-impregnated, foam synthetic rubber, which is self-lubricating.

QZ Lubricator supplies the required amount of lubricant to the LM rail raceway. An oil film is continuously formed between the rolling element and raceway, extending the lubrication and maintenance intervals significantly.
Three major elements make up the QZ lubricator structure:
A heavy oil-impregnated fiber net, which stores lubricant.A high-density fiber net, which applies lubricant to the raceway.An oil-control plate, which adjusts the oil flow.
The lubricant contained in QZ Lubricator is fed by the capillary phenomenon as the fundamental principle. The lubrication maintenance interval can be significantly extended, as it supplements an oil loss. The QZ lubricator is an eco-friendly lubrication system that does not contaminate the surrounding area, as it feeds the required amount of lubricant to the ball raceway.
