TORQUE LINEAR BEARINGTECHNICAL DATAConstruction and CharacteristicsThe torque ball bushing allows the establishment of a precision longitudinal track using two components: thebearing and a profiled shaft. Shafts for torque linear bearings: Material: Cf53, precision drawing andinductive hardening.Both the bearing and the shaft have 3 or 4 ball tracks shaped like gothic arches, which form a 4-pointcontact with each load-bearing ball.The construction of the tracks ensures a very precise movement of the bearing for loads from any direction.They are high-frequency hardened along their entire length. Due to the plastic cage and the robustconstruction, the noise and vibration of the bearing could be significantly reduced.Freedom from PlayThe prestressing of the torque bushing permits theadjustment of the system free of play, thus increasingrigidity.lubricationboringballsConstruction ofball trackIncreased Dynamic Load RatingThe implementation of the ball tracks in the form of agothic arch increases the contact surface of the balls.This has allowed the load capacity of the constructionto be significantly increased.cageouter ringSealsAll torque ball bushings are delivered with seals on both sides which fit perfectly into the profile groove ofthe shafts. This results in a secure seal as well as a large lubrication space in the bearing. The bearings can berelubricated using the bearing nipples provided.Small Space RequirementsThe outer diameter of the bearing has been kept to a minimum. The return of the balls was optimised fromthis standpoint.Radial PlayOf great significance for the precision and service life of the system in a given application is the selection ofthe right radial play. For unpaired units, the radial play cannot be definitely specified (increased radial playand/or increased prestressing are possible.) The value of the prestressing for the individual bearing sizes aregiven in the table.Designation of units:SSP202 T1360ConstructiontypeNumber ofbearings pershaftNo prestressing,T1 mild prestressing,T2 average prestressingShaft lengthExample applications:Average prestressing T2Strong vibration, frequently changing load directions (welding machines, cutting tables.)Mild prestressing T1Mild vibrations, changing load directions (robot arms, XY tables, assembly machines.)No prestressing T0Very little vibration, load only from one direction (measurement equipment, packaging machines.)MINITEC LINEAR SYSTEM 39
