The 3-jaw puller with cone knob has been developed for the proper extraction of rolling bearings in collaboration with a Scandinavian ball bearing manufacturer. Both the proportions of the puller and the consistently straight puller jaws are specifically tailored to the requirements for centric pulling of small and medium-sized bearings under limited environmental conditions. This prevents potential damage to the bearing and bearing seat during extraction. The springs guarantee a synchronous opening and closing of the puller jaws, enabling easier handling and even more efficient working. The combination of a tightened reach adjusting knob and spring element prevents the puller from slipping and ensures a particularly firm hold at all times. At the same time, the fixation of the jaws is accelerated and facilitated by the cone knob, making work easier when performing consistent pulling operations with an identical spread. The 3-jaw design guarantees an even load distribution and thus a particularly secure hold on the part to be pulled.Automatic self-centering of the jaws by tightening the tension ringThe tension ring and spring ensure a force-fitting fixation of the puller without slipping or deflection of the jaws.
