Tapered roller bearings are separable bearings, inner and outer ring of the bearing with tapered Raceway. The bearings according to the number of columns to complement into variable-column and four-column and single row tapered roller bearings of different structural types. Single row tapered roller bearings can accommodate radial loads and single direction axial loads. When the bearings are subjected to a radial load, will have an axial force, another affordable anti-so when you need to be balanced bearing in the axial direction. Single row tapered roller bearings are subjected to axial load carrying ability depends on the contact angle, outer ring raceway of that angle, angle, the greater, the axial load carrying capacity is also bigger.   Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged, their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial ) load.        
Tapered roller bearings have single, double and four rows.  We manufacture both metric and inch size tapered roller bearings.     Use:   Tapered roller bearings are widely used in automotive, mill, mine, metallurgy, plastics machinery industry       Packaging & Shipping   Packing:     1)      Barreled package+outer carton+pallets   2)      Single box+outer carton+pallets   3)      Tube package+middle, box+outer, carton+pallets   4)      According to your requirement.     Delivery:     Detailed Images   Production show:              ...
