Inch tapered roller bearing

Inch tapered roller bearing structure and assembly dimension accuracy and rotation accuracy is different from the metric bearing. Used for imports of machinery, or special needs of industry.

This kind of four row roller bearing, can take great radial load, and can carry two-way axial load, limit rotational speed is low. It is widely used in all kinds of cold and hot rolling mill. Bearing inside diameter and the roll diameter using the transition fit. The size of the axial clearance of tapered roller bearing can be normal working relationship is great, clearance after hours, the temperature rise is higher; Clearance is bigger, bearing damage easily, so when installation should pay special attention to three outer and two inner ring, two outer baffle, a baffle in factory type number, don't wrong.

Four row circular cone roller bearings is one of the main roller bearing, such bearing radial and axial load capacity is large, the radial load capacity of about 3 times of single row, can withstand larger bidirectional axial load, but limit rotational speed is low. It can limit shaft (or shell) axial displacement of two direction within the scope of the bearing axial clearance, therefore can be used as a bidirectional axial positioning. But by changing the inner and outer ring baffle between thickness to adjust bearing diameter, the axial clearance.

Four row circular cone roller bearings are mainly used for hot rolling mill and cold rolling mill work roll, and roughing mill roll, etc. Due to the convenient for loading and unloading, usually with the roll neck into a clearance fit. Tapered roller bearings generally adopts the stamping steel cage, the larger size, the use prop cage.
