(495)-921-34-60Technical dataGeneral informationThe general technical data applies toall rail guides (all carriages andrails).Special technical data is listedseparately for the individual designs.Preload classesIn view of the different user requirements,the ball rail guides can besupplied in four different preloadclasses.So as not to reduce the servicelife, the preload should not amountto more than 1/3 of the bearingload F.In general, the stiffness of thecarriage increases according to thepreload increase.Guide systems withparallel rails• In connection with the selectedpreload class the permissibledeviation in parallelism of therails must also be taken intoaccount (see tables for thevarious designs).• For the installation of rail guides inthe accuracy class P5 werecommend the version withclearance T0 or the preloadclass T1 in order to avoidstresses owing to thetolerances.Speedv max : 5 m/sAccelerationa max : 500 m/s 2Only in the case of preloaded systems.In the case of non-preloaded systems:a max = 50 m/s 2Material specifications1 Recirculation parts:POM (PA6.6)2 Lubrication nipple:carbon steel3 Metal front plates:1.43014 Seals: TEE-E5 Flange screws:carbon steel123Temperatureresistancet max : 100 °CThis is a maximum value which isonly permissible for a short time.
