2-Arm MECHANICAL PULLERS BETEX 46 Simple, handy 2-arm puller for parts gripped externally like pulleys, bearings, rings, etc. Suitable for removing fans from electric motors. During operation the arms cannot slip because they are pressed against the cross bar. The higher the necessary pulling force, the stronger the arms are pressed against the cross bar. The one-hand operation of the puller permits easy use even under unfavorable conditions. A spring inside the housing guarantees a continual clamping of the forged alloy steel arms.
