5 Technical instructionsLubricationRoller pin lubricationThe bearings inside the Rollers are lubricated for life. Custom lubricationof the roller sliders for use in high temperature environments or in the foodindustry is available upon request. For more information, please contactthe Rollon Application Engineering department.Lubrication of the racewaysProper lubrication during normal conditions:■ reduces friction■ reduces wear■ reduces the load of the contact surfaces through elastic deformations■ reduces running noise■ increases quiet runningTo reach the calculated service life (see pg. 56), a film of lubricant shouldalways be present between the raceway and roller, this also serves toprotect against corrosion of the ground raceways.N-slider lubricationLubrication when using N-slidersNTE-, NUE- and NKE-sliders (except for types NT/NU18) are equipped witha self-lubrication kit for periodic lubrication of the slider.This provides a progressive release of lubricant (see tab. 36) on the racewayduring operation of the slider. The expected service life is up to2 million cycles, depending on the type of application. The zerk fittings(see fig. 94) provide the lubrication.Lubricant Thickening agent Temperature range[°C]Dynamic viscosity[mPas]Mineral oil Lithium soap -30... to +120 < 1000Tab. 367 2,5M6 x 1SW 76,57Fig. 94Replacement of N-slider wiper headSliders NTE, NUE and NKE are equipped with a safety system made oflongitudinal sealing lips and rigid, spring-preloaded, and therefore selfadjusting,wipers on both sides of the head for automatic cleaning of theraceways. The slider heads can be removed for replacement. To do this itis necessary to loosen the zerk fittings (except for types NT/NU18), whichshould be refastened after installing the new heads with the followingtightening torque:Slider typeTighteningtorque [Nm]NTE, NUE28 0.4 - 0.5NTE, NUE, NKE43 and 63 0.6 - 0.7Tab. 3758 www.rollon.com
