YDTech® manufacturer of precision double or two tapered roller bearings; supplier of loose 2 row tapered roller bearings in china.

double or two row tapered roller bearings can carry heavy loads and are stiff. They are suitable for the accommodation of combined loads and can locate a shaft axially in both directions with a given axial clearance or a given preload. Their main use is in gearboxes, hoisting equipment, rolling mills and machines used in the mining industry, e.g. tunnelling machines.

Tapered roller bearings were a breakthrough at the end of the 19th century because bearings used in wheel axles had not changed much since ancient times. They relied on bearings enclosed in a case that held lubricants. These were called journal bearings and depended on lubricants to function.

In many applications tapered roller bearings are used in back-to-back pairs so that axial forces can be supported equally in either direction.

Without proper lubrication,these bearings would fail due to excessive heat caused by friction. we are able to significantly reduce the friction on his bearings by using a cup and cone design incorporating tapered bearings which actually rolled, which reduced the load placed on the bearings by distributing the weight and load evenly across the cups, cones, and bearings.
