... to Easier Mounting all the Way Down to the Reduction of Noise
With the eccentric unit for embroidery heads (see illustration below left), you can obtain a clever system solution from us that is suitable for single or multiple embroidery heads. This INA subassembly comprises a lever, eccentric, connecting rod and the corresponding Bearing units and simplifies the overall design of the machine. The gearing becomes unnecessary since the eccentric converts the rotary motion of the drive shaft to the up-and-down motion of the embroidering process. More than 1,000 strokes a minute are possible with our smoothrunning precision rolling bearings. The effective seal enables you to save maintenance costs during the entire, long operating life. Yoke type Track rollers are another INA and FAG specialty. In weaving Machines, for instance, they are used in the slay drive or in the gripper drive. Yoke type track rollers convert the rotating motion of the cam disk and eccentric disk to a precisely defined and calculated backand-forth motion. In the process, forces occur that can vary greatly in one cycle. These forces can increase very quickly, which can produce a strong impact on the bearing. That’s why our Pulleys have especially thick walled outer rings made from special rolling bearing steels. The optimized design of the tires means that slanted positions can be compensated and the contact pressure between the raceways can be considerably reduced. This means longer life for the bearings and the adjacent construction. Cylindrical Roller bearings allow the construction of locating and non-locating bearing solutions with high load carrying capacity in the Gearboxes of weaving machines. FAG Cylindrical roller bearings are especially suitable for this application since they run reliably even with marginal lubrication or high vibrations. The materials and geometry of the bearing cages are as varied as the operating conditions. A geometrically-stable sheet steel cage for high temperatures, a rib-guided solid brass cage for strong vibrations or high speeds or a completely new design for a special application? Just ask us – we are your development partner!
