Itis necessary to prevent foreign matter from entering the system. Therefore, when possible entranceof foreign matter is predicted, it is important to select an effective sealing device or dust-preventiondevice that meets the working conditions.123End sealUsed in locations exposed todust.Side sealUsed in locations where dustmay enter the LM block from theside or bottom surface, such asvertical, horizontal and invertedmounts.Side sealEnd sealDouble sealsUsed in locations exposed tomuch dust or many cutting chips.End sealSeals and Scrapersz to c SealsHighly wear-resistant end seals made of special resinrubber and side seals for increased dust-prevention effectare available.If desiring a dust-prevention accessory, specify it with thecorresponding symbol indicated in table 3.For the supported model numbers for dust-prevention accessoriesand the overall LM block length with a dust-prevention accessoryattached (dimension L), see table 4.Seal resistance valueFor the maximum seal resistancevalue per LM block when a lubricantis applied on seal SSR … UU, referto the corresponding value providedin table 1.Table 1 Maximum Seal Resistance Valueof Seal SSR … UUUnit: NModel No.15X20X25X30X35XSeal resistance value2.02.63.54.96.3vb ScrapersLaminated Contact Scraper LaCSFor locations with an even more adverse workingconditions, the Laminated Contact Scraper LaCS isavailable.LaCS prevents minute foreign matter from entering the LMblock by removing such foreign matter adhering to the LMrail in multiple stages through a laminated contactstructure (3-layered scraper).FeaturesSince the 3 layers of scrapers fullycontact the LM rail, LaCS is highlycapable of removing minuteforeign matter.Since it uses oil-impregnated,foam synthetic rubber with a selflubricatingfunction, low frictionresistance is achieved.Basic Specifications of LaCS1 Service temperature range ofLaCS: -20 C to +80 C2 Resistance of LaCS: indicated intable 2*Note that LaCS is not sold alone.Table 2 Resistance of LaCSUnit: NModel No. Resistance of LaCS15X5.920X6.925X8.130X12.835X15.1Note 1: Each resistance value in the tableonly consists of that of LaCS, anddoes not include slidingresistances of seals and otheraccessories.Note 2: For the maximum service speedof LaCS, contact THK.n Light Sliding Resistance Contact Seal LiCSLiCS is a contact seal with a low sliding resistance. It iseffective in removing dust and the like from the racewayand retaining a lubricant such as grease. With its very lowsliding resistance, LiCS achieves a smooth and stablemotion.
