QZ Lubricator QZ Casing (2) High-density fiber net (1) Highly oil-impregnated fiber net (End seal) Ball (3) Oil control plate Flow of lubricant Ball cage The structure of the QZ Lubricator consists of three major components: (1) A highly oil-impregnated fiber net (functions to store a lubricant) (2) A high-density fiber net (functions to apply the lubricant to the raceway) (3) An oil control plate (functions to control the flow of the lubricant) The lubricant contained in QZ Lubricator is fed to the LM system based on the principle of capillary action, which is used in felt-tip pens and other products. The QZ Lubricator feeds the right amount of lubricant to the raceway of the LM rail. This allows an oil film to be constantly formed between the rolling elements and the ball raceway, thus significantly extending the lubrication maintenance interval. Features Since it supplements an oil loss, the lubrication maintenance interval can be significantly extended. Since the right amount of lubricant is applied to the ball raceway, an environmentally friendly lubrication system that does not contaminate the surroundings is achieved. It allows the user to select a lubricant that meets the intended use. Significantly Extended Maintenance Interval Attaching the QZ Lubricator helps extend the maintenance interval throughout the whole load range from the light-load area to the heavy-load area. Applications The QZ Lubricator provides an optimal lubrication system for the following requirements. To introduce an eco-friendly machine. To prevent contaminating the surroundings of the machine/ equipment. To eliminate the waste of grease or oil used in the LM Guide. To minimize the piping of the machine. To extend the greasing interval or want to stop greasing. To lubricate the machine only with oil (want to avoid grease lubrication). Grease lubrication Forced centralized lubrication QZ Lubricator LM Guide attached with the QZ Lubricator Note 1: The QZ Lubricator has an air vent. Do not block the vent with grease or the like. Note 2: Those LM Guide models attached with the QZ Lubricator cannot have a grease nipple. When desiring both the QZ Lubricator and a grease nipple to be attached, contact THK. Note 3: The QZ Lubricator is not sold alone.

Laminated Contact Scraper LaCS Optimal for use in harsh environments subject to foreign material such as fine dust and liquids. Ball cage Ball Laminated Contact Scraper LaCS Liquid Large amount of foreign material For locations with an adverse atmosphere, Laminated Contact Scraper LaCS is available. LaCS removes minute foreign material adhering to the LM rail in multiple stages and prevents it from entering the LM block with its laminated contact structure (3-layer scraper). Features Since the 3 layers of scrapers fully contact the LM rail, LaCS is highly capable of removing minute foreign material. Since it uses oil-impregnated foam synthetic rubber with a self-lubricating function, low friction resistance is achieved.

Light Sliding Resistance Contact Seal LiCS LiCS LiCS LiCS is a contact seal with a low sliding resistance. It is effective in removing dust and the like from the raceway and retaining a lubricant such as grease. With its very low sliding resistance, LiCS achieves a smooth and stable motion. Features Light Sliding Resistance Contact Seal LiCS is a contact seal that uses a low sliding resistance material for the seal and contacts with the LM rail raceway. It is optimal for locations requiring a low sliding resistance such as semiconductorrelated machines, inspection machines and OA equipment, which are used in favorable service conditions. Effective in removing dust or the like adhering to the LM rail raceway with a seal that contacts the raceway. Use of oil-impregnated, foamed synthetic rubber, which is high selflubricating, achieves a low sliding resistance. LiCS model SSR is attached with a grease nipple as standard. For the mounting location of the grease nipple and the incremental dimension with the grease nipple attached, see page 16. LiCS models include types that also support other Caged Ball LM Guide models such as SHS. Contact THK for details. Basic Specifications of LiCS Service temperature range: - to +80 Resistance of LiCS: For seal resistance of LiCS, see the table below. Maximum Seal Resistance of LiCS 15X X SSR X X X SRG 15X Resistance 1 1.1 1.6 1.6 2 0.7 Unit: N Note: Each value represents the sliding resistance of 2 LiCS units per LM block, one unit on each end, and excludes the sliding resistance of the block and any other seals. Note: LiCS is not sold alone.

Metal Cap Dedicated for LM Rail Mounting Holes GC Cap GC Cap LM rail GC Cap LM rail Magnified view LM rail mounting bolt GC cap is a metallic cap that plugs the LM rail mounting hole (article compliant with the RoHS Directives). It prevents the entrance of foreign material and coolant from the LM rail top face (mounting hole) under harsh environments, and significantly increases the dust control performance of the LM Guide if used with a dust control seal. Features Eliminates the clearance between the mounting hole (counterbore hole) and itself Since GC Cap is driven into a mounting hole (counterbore hole), it does not leave a clearance. Eliminates the clearance Mounting method To insert GC cap into a mounting hole, use a flat metal piece like the one shown in the figure, and gradually drive the metal cap until its top is on the same level as the LM rail top face. When inserting GC cap, do not remove the LM block from the LM rail. Demonstrates a sealing effect over a long period due to superb resistance to wear If a dust control seal or the like passes over the top face of the LM rail to which foreign material adheres, a downward force from the top of GC cap is generated. Since the metal cap has a sufficient retention, it does not sink even in such a case. Dust control seal passes Dust control seal Adherence of foreign material Does not sink

Handling Precautions on Use QZ Lubricator for the LM Guide Dropping or hitting this product may damage it. Take much care when handling it. Do not block the air vent with grease or the like (see page 5). Service environment The service temperature range for this product is between -10 and +50. Do not clean the product with an organic solvent or white kerosene, or do not leave the product unpacked. When desiring to use the product out of the service temperature range, contact THK in advance. Use in a special environment When desiring to use the product in a special environment, contact THK in advance. Precaution on selection The stroke must be equal to or longer than the overall LM block length with QZ Lubricator attached. Rust prevention of the LM Guide QZ Lubricator is a device designed to feed the required minimum amount of lubricant to the raceway, and therefore it does not have a dust-prevention effect on the whole LM Guide. When using it in an adverse environment subject to a coolant or the like, we recommend applying grease or the like to the mounting base surface and the rail ends of the LM Guide as an anticorrosive measure. Laminated Contact Scraper LaCS and Side Scraper for the LM Guide Service environment The service temperature range is between - and +80. Do not clean the product with an organic solvent or white kerosene, or do not leave the product unpacked. Impregnating oil The purpose of the lubricant impregnated in the scraper is to increase the slidability of the scraper. For lubrication of the LM Guide, attach a grease nipple on the end plate side face of QZ Lubricator or the LM block before feeding oil. Functions Although these products have a dust prevention ability to remove foreign material and liquids, they require an end seal to seal grease and oil. Design When using these products, be sure to use the rail cap GC and a plate cover. Light Sliding Resistance Contact Seal LiCS for the LM Guide Service environment Options for the LM Guide The service temperature range is between - and +80. Do not clean the product with an organic solvent or white kerosene, or do not leave the product unpacked. Since the product contacts the LM rail raceway only, do not use it in a harsh environment. Impregnating oil The purpose of the lubricant impregnated in LiCS is to increase the slidability of the seal. For lubrication of the LM Guide, attach a grease nipple on the end plate of the LM block before feeding oil. GC Cap Handling If you selected the GC Cap, take much care not to hurt your finger or hand when attaching the metal cap to the LM system since the mouth of the LM rail mounting hole is sharp. When attaching the GC Cap, gradually drive the metal cap from the top surface of the LM rail using a flat metal piece until the metal cap top is on the same level as the top surface of the rail, and then smooth out the top surfaces of the rail and the GC Cap using sandpaper, oil stone or the like so that the surfaces become even, before using the product.
