12. Thrust needle roller bearings
Separable bearings are composed of raceway rings, needle rollers and cage assemblies, and can be arbitrarily combined with stamped thin raceway rings or cut-processed thick raceway rings. Non-separable bearings are integral bearings composed of precision stamped raceway rings, needle rollers and cage assemblies. They can withstand unidirectional axial loads. This type of bearing takes up little space and is conducive to the compact design of machinery. Most of them Only the needle roller and cage assembly is used, and the mounting surface of the shaft and housing is used as the raceway surface.

Main uses: transmission devices for automobiles, cultivators, machine tools, etc.

13. Thrust tapered roller bearings
This type of bearing is equipped with truncated cone-shaped rollers (the big end is spherical). The rollers are accurately guided by the ribs of the raceway ring (shaft ring, seat ring). The design ensures that the raceway surfaces of the shaft ring and seat ring and the rolling surface of the rollers are The apex of each conical surface intersects at a point on the bearing center line. One-way bearings can bear one-way axial load, and two-way bearings can bear two-way axial load.

The main purpose:
One-way: Crane hook, oil drilling rig swivel.
Both directions: rolling mill roll neck.

14. Insert spherical ball bearing with seat
The seated spherical ball bearing is composed of an spherical ball bearing with seals on both sides and a cast (or steel plate stamped) bearing seat. The internal structure of the outer spherical ball bearing is the same as that of the deep groove ball bearing, but the inner ring of this bearing is wider than the outer ring. The outer ring has a spherical outer surface, which can be automatically aligned with the concave spherical surface of the bearing seat.

Main uses: mining, metallurgy, agriculture, chemical industry, textile, printing and dyeing, conveying machinery, etc.
