The back-up rollers with stud are used when the the sheet metal to level has little relevant thickness. Unlike the previous execution the stud facilitates the mounting on the machine. The usual internal execution provides needle roller cages because the load to support is normally lower than the previous version. For a good distribution of the applied load these bearings have a very thick outer ring with optimized outer profile suitable to compensate the possible misalignment of surrounding parts of the machine. The rings and the stud are made in hardening and tempering steel (100Cr6 & 100CrMo7) with high hardness (up to 62 HRc). The stud can be made also in case hardening steel in relations to the dimensions. They are available with sealing system (lamellar double or triple rings), thermoplastic seals and labyrinth system. They are generally mounted in line so on request they can be supplied in pre-selected groups to be mounted on the same row of the bank machine. Alpha Wälzlager GmbH produces levelling back-up roller with stud of any execution design for any application (please contact our technical department for any further informations)
