Walther Flender Gruppe Clamping sets Page 40 MLC 7000 This model, similar to the MLC 4000 series, can withstand very high loads and is especially suitable for a smaller diameter range and a shorter installation length. The diameter gradations are the same. These clamping sets are self-centring and self-locking with excellent concentricity and runout properties, also compared with resulting torques. The very small taper angles mean that the clamping travel is relatively large. The inner clamping ring requires greater axial clearance for release (s = 0.02 · d).

Walther Flender Gruppe Clamping sets Page 41 Taper Lock® clamping bushes In addition to the cylindrical clamping elements listed here, we also offer an extensive line of conical TL clamping elements. Installation Clean and degrease all exposed surfaces. Fit pulley and bush, align holes and screw in screws loosely. Push pulley with bush onto the shaft, align and tighten screws evenly to the correct torque according to the table. The empty bores should be filled with grease to prevent penetration by foreign objects. 1008 to 3030 Disassembly Remove screws, insert one as a pushoff screw into the hole with a half thread in the bush and tighten. This loosens the Taper Lock® bush. Remove the loosened pulley unit – without impact to prevent damage to the machine – by hand. 3525 to 5050 If high torques have to be transmitted and no feather key is used, the Taper Lock® clamping bush can be driven further into the conical bore by lightly tapping with a hammer, using a suitable sleeve or wooden block. Afterwards, the screws can be tightened a bit more. This procedure can be repeated. * The specified slipping torques were measured on test stands. The screws were tightened to the corresponding torque. Taper Lock® is a trademark of J. H. Fenner and Co. Ltd.
