Selection of frame type
Common slewing ring classifies into four types: Single-row ball, two-row ball, cross-rolling pole, three-row pole
According to our experience and calculation, we have conclusion as follows:
Bearing capacity of single-row ball slewing is more than cross-row pole with same figure dimension.
Below 160 ton meters load of incline moment, adopts single-row ball slewing bearing can get higher quality & price rate than threw-row pole slewing bearing, that is principal selection. While when incline moment is longer than 160 tons meters, should consider three row pole slewing bearing.
2. Selection of single-row slewing bearing series
Domestically, at present single-row slewing bearing has specifications of 3 series: HS series and 01 series. New clients usually don't know how to choose, we think each series has its own adantage, we analyze as bellows:
