Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged, Their rolling elements linearly come into contact with the raceways of inner ring and outer ring. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load and also can take the axial load only. The larger the contact angle is, the higher the axial capacity can be loaded.
In order to achieve pure rolling, all the extended lines of which roller and raceway contact must be designed to meet the same point in the shaft center line.
The new designed bearings use the enhance frame. The size of roller is extended both in length and radial. The quantity of roller is increased. The new designs also use the special rollers that have bulgy surface. All of these make the bearings take higher load and have longer life. The big flat of roller contact the big block in the way of spherical surface and cone-shaped surface contacted. Therefore, the design improves the lubricating condition. We manufacture both metric and inch size tapered roller bearings. |
