44 Example of function for T Line low clamping force medium clamping force high clamping force Range of axial force per coloured ring Technical features: Spring loaded centres with pressure indication by yellow, green, red rings. Designed for high radial and axial loads and for higher speeds. High precision bearings in the head of the housing and within the taper. T he bearing seats of housing and centre spindle are matched to the bearings and ground to precise tolerances. High concentricity accuracy tested under axial load and guaranteed with test report. Housings and centre spindles are hardened. Rotary seals protect bearings from dirt and coolant. Maintenance-free due to permanent lubrication. Applications: Multi-spindle machines CNC lathes without tailstock CNC lathes with opposed spindle Design principle on page 35, type LR High Performance Live Centres T Line Housing ∅ DG axial force daN 55 0-250 250-500 500-850 68 0-350 350-620 620-850 Reduction of spring force through soft spring on request
