slewing bearing wear measurement

How to conduct a rocking test of the crane?

Answer:The slewing bearing rocking test should be done periodically for the bearing wear tracking and early failure detection. The measurement could be done from the inside and outside of pedestal. INSTALLATION AND MAINTENANCE OF SLEWING RING seizure; both of which will reduce slewing ring bearing service life. annually to determine the amount of wear in the bearing. Measurements must be taken as close to the raceway as possible to minimize elastic deflections in the structure and entered into the machines maintenance logs.

Marine Crane Slewing Bearing Inspections Alatas Crane

Jan 04, 2021 · Classification organisations require a cranes slewing bearings to be assessed for wear every year. During these inspections, the bearing clearance is measured, grease is taken for a ferrography analysis and, in the case of Class ABS, that slewing bearing bolts are NDT tested. Without accurate slewing bearing inspections, the classification may not be completed, and more wear may Rocking test of deck crane - DieselShipApr 12, 2020 · Rocking test of deck crane is carried out to ascertain the wear down of the sleeve bearing of the deck cranes by measuring the play (relative movement) between the inner and outer bearing race. This measurement indicates the rate of wear. Usually the wear down is also identified by analyzing the grease sample taken from the bearing housing. Rothe Erde Slewing Bearings.Rothe Erde manufactures slew- ing bearings up to 8,000 mm diameter as monobloc systems and segmental bearings in larger dimensions. Rothe Erde slewing bearings are manufactured in Germany and by Rothe Erde subsidiaries in Great Britain, Italy, Spain, the United States, Brazil, Japan and China.
