Design ConsiderationsProduct DescriptionPrecision Steel ShaftsLINTECH's SL shafting and SA and TRSA shaft assembliesuse Rockwell 60-65C hardened and ground steelshafts as the inner race in this highly reliable linear bearingsystem. These high quality carbon steel shafts are accuratelymachined and precisely heat treated for uniform hardness.They are also inspected for straightness, roundness, andsmoothness. The high hardness and extremely smooth surfaceof the steel shafts creates an abrasion-resistant surface,which reduces material wear and system friction, whilemaintaining an optimal surface finish.Shaft Assembly SupportsLINTECH shaft assemblies (SA and TRSA series) use6061-T6 precision machined aluminum supports. Theseblack anodized supports have pre-drilled base mountingholes that come in both single supports for the SA, andTWIN RAIL ® supports for the TRSA. These precision machinedsupports come in 6, 12, 18, and 24 inch lengths, andcan be combined for nearly unlimited assembly lengths.SA Series - single rail supported asemblyAStainless Steel ShaftsFor corrosion resistant applications, LINTECH provides440C stainless steel shafts with the same shaft diametertolerance, hardness depth, and straightness as our standardsteel shafts. Stainless steel shafts are recommended for usein chemical and food processing industries, for medicalequipment in corrosive environments, or in strong oxidizingatmospheres where no lubricating oil is available.Chrome Plated Bearings & CarriagesLINTECH can also provide corrosion resistant linear bearingsand shafts. All metal hardware is either stainless steelor chrome plated.Pre-Mounted ShaftBase Mounting HolesTRSA Series - TWIN RAIL ® supported assemblyPre-Mounted &Pre-Aligned ShaftsBase Mounting HolesShaft Diameter ToleranceLINTECH shafts are precision ground to a very closediameter tolerance. This diameter tolerance is an extremelyimportant factor when using LINTECH linear bearings. Itassures a dependable fit, with proper clearance between ashaft assembly and linear bearing.Shaft HardnessThe hardness of a steel shaft is its ability to prevent nicks,indentations, or grooving. It is an important factor in determiningthe life of a linear bearing system in an application.The heat treatment process performed on all shafts assuresuniform hardness in radial and axial directions.Hardness DepthShaft Component SupportsLINTECH ES end supports use 6061-T6 aluminum (-A),or 1045 steel (-S). These supports slide over the hardenedshaft, and have a screw that is adjusted to "clamp" thesupport onto the shaft. The assembly support (ARS series)is manufactured from aluminum. The low profile support(LSRS series) is manufactured from C-1018 steel and functionsthe same as the ARS series, but has a smaller overallheight. The LSRS is the only support that is mounted fromthe mounting surface "up".ES-A SeriesES-S SeriesBase Mounting HolesARS SeriesLSRS SeriesShaft StraightnessThe exceptional straightness of all shafts eliminate systembinding when using a TRSA shaft assembly with a TRCAcarriage assembly, and helps the alignment process whenusing two SL shafts, or SA shaft assemblies, in a parallelassembly application.Base Mounting HolesLINTECH ®Positioning ComponentsA-5
