The ZKLN and ZKLF series (with flange mounting) are now complemented by the three-row DKLFA design. The hybrid version (DKLFA-HC) delivers outstanding operational reliability, particularly in short-stroke applications and under conditions involving vibrations occurring at standstill. In certain sectors, such as mold making and medical technology, short-stroke applications can lead to premature failures of the axial bearings in screw drives, typically indicated by increased noise from the screw spindles. The associated damage pattern, known as false brinelling, typically occurs when bearings are subjected to repeated small oscillating movements and angles. 100 percent hybrid bearings: a strategic approach The damage pattern known as false brinelling remains difficult to predict and can occur after only a few hours of operation. For machine manufacturers, this can result in significant repair costs as well as reputational damage. For affected machine types, a full transition to hybrid screw drive bearings is advisable as a standard solution. Hybrid bearings ensure a very high level of operational reliability in both short-stroke applications and situations involving vibrations at standstill. With these bearings, machine downtime and costly service operations caused by false brinelling can be reliably avoided. Importantly, the dynamic load-carrying capacity and calculated rating life of the bearings remain completely unchanged.</span></p>
