Weighting Arms for Worsted Ring Frames

Pre-calibrated weighting arms

TeraSpin weighting arms are characterised by their robust design and corrosion resistant finish. Not only are these weighting arms built to last the lifetime of the ring frame, but each weighting arm exerts the same load on all the top rollers irrespective of how long the arm has been in use or at what position on the machine it is fastened. Loading springs used on TeraSpin weighting arms are pre-calibrated for specified loads for an unlimited period of time.
