The axle on which the roller rotates can be an open axle (mount­ed with an M16 bolt) or a sup­port­ing jour­nal with a hexa­gon on the head side and a nut with lock­ing ring. As stan­dard, the axles are designed for M16 threads, but oth­er dimen­sions are also avail­able. 

For relu­bri­cat­able sys­tems, the axle can also be designed with a grease nip­ple. In this case 6005 bear­ings and/or 6206 bear­ings with grease fill­ing between the two bear­ings and the open spaces are used. The stan­dard met­al caps and rings should then be replaced with con­vex met­al caps and rings that allow less grease to pass through. The grease pass­es between the two bear­ings via a grease nip­ple at the head end of the axle. The con­vex met­al caps and rings are secured by means of lock­ing rings. The cast-iron shak­ers are pitch-bound and are mount­ed with an extend­ed axle in the gear­wheel run of the rod belt. The shak­ers are set in motion by the rod belt and the desired shak­ing effect is achieved by the tri­an­gu­lar shape of the teeth. The uni­ver­sal rub­ber shak­ers and the tri­an­gu­lar toothed rub­ber shak­ers are mount­ed below the rub­ber belt and are pitch-inde­pen­dent. Like the rollers, all shak­ers are mount­ed with two ball bear­ings and seals each.
