Four Rows Tapered Roller Bearing
1.Special features:
1. Tapered roller bearings are assembled such that cup,component of cone,rollers and cage parts.
2. It provides a high capacity for radial loads, axial loads and combined loads.
3. The inner and outer rings are separable, each ring can be mounted individually.
4. Tapered roller bearings can be disassembled into subunits, dimensions are standardized in ISO or AFBMA standards, provide interchangeability within each dimensional standard.
5. The spherical roller thrust bearings incorporates a maximum number of large diameter and extra long rollers. The high degree of roller raceway conformity ensures even load distribution and a high carrying capacity
6. Bearing load capacity depends on the angle of the outer ring raceway, the greater the angle the greater the carrying capacity.
2.Application
This bearing is widely used in heavy-duty machine tools, high power gear case for vessel, petroleum drilling machines, vertical machine, etc.
3.Packing
Generally bearing is to be packed in plastic tube, antirust paper, individual paper box , then in cartons, then in wooden pallets.
