TURMOGREASE Highspeed L 252 Suitable for the lubrication of spindle and cylindrical roller bearings for bore sizes of the inner ring d < 100 mm. It is the special grease to be used for high-speed rolling bearings up to Dm x N = 220 x 10 4 (rpm x mm). TURMOGREASE Highspeed L 182 This grease is particularly well suitable for smaller rolling bearings (d < 25 mm) and very high speed factors up to Dm x N = 250 x 10 4 (rpm x mm). Grease 32

UNBALANCE 1X RPM always present and normally dominates Amplitude varies with square of increasing speed Can cause high axial as well as radial amplitudes 102
ANGULAR MISALIGNMENT PARALLEL MISALIGNMENT 1x 2x 4x Radial 103
BENT SHAFT Bent shaft problems cause high axial vibration 1X RPM dominant if bend is near shaft center 2X RPM dominant if bend is near shaft ends 104
MECHANICAL LOOSENESS (C) Phase is often unstable Will have many harmonics Can be caused by a loose bearing liner, excessive bearing clearance or a loose impeller on a shaft 105
