PRODUCT DETAILS
The inch four-row tapered roller bearing is one of the main roller bearings. This type of bearing has a large radial and axial capacity, and the radial load capacity is about three times that of a single-row tapered roller bearing. It can withstand large bidirectional axial loads, but the limit speed is low. It can limit the axial displacement of the shaft (or housing) in both directions within the range of the bearing axial clearance, so it can be used for bidirectional shaft positioning. The diameter and axial clearance of the bearing can be adjusted by changing the thickness of the spacer between the inner and outer rings. Mainly used for the work rolls of hot rolling mills and cold rolling mills, as well as the rolls of blasting machines.
