It isnecessary to prevent foreign matter from entering the system. Therefore, when possible entrance offoreign matter is predicted, it is important to select an effective sealing device or contaminationprotection device that meets the working conditions.1End sealUsed in locations exposed to dust.End sealSeals and Scrapersz to v SealsHighly wear-resistant end seals made of special resin rubber and sideseals for increased contamination protection effect are available.If desiring a contamination protection accessory, specify it with thecorresponding symbol indicated in table 3.For the supported model numbers for contamination protectionaccessories and the overall LM block length with a contaminationprotection accessory attached (dimension L), see table 4.2Side sealSide sealUsed in locations where dust mayenter the LM block from the side orbottom surface, such as vertical,horizontal and inverted mounts.Seal resistance valueFor the maximum seal resistancevalue per LM block when a lubricantis applied on seals SHW … UU/SS,refer to the corresponding valueprovided in table 1.Table 1 Maximum Seal Resistance Valueof Seals SHW … UU/SS Unit: NModel No.Seal resistance valueUU SS12CA/CR 1.0 1.412HR 1.0 1.8141.2 1.8171.4 2.2214.9 6.9274.9 8.9359.8 15.850 14.7 22.734Inner sealUsed in locations severely exposedto dust or cutting chips.Inner sealDouble sealsUsed in locations exposed to muchdust or many cutting chips.End sealbn ScrapersLaminated Contact Scraper LaCS®For locations with an even more adverse working conditions, theLaminated Contact Scraper LaCS is available. LaCS preventsminute foreign matter from entering the LM block by removingsuch foreign matter adhering to the LM rail in multiple stagesthrough a laminated contact structure (3-layered scraper).FeaturesSince the 3 layers of scrapers fullycontact the LM rail, LaCS is highlycapable of removing minute foreignmatter.Since it uses oil-impregnated, foamsynthetic 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 LaCS213.9276.53513.05019.5Note 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.
