Used in crane hooks thrust bearing 51230 (NSK)

Thrust ball bearing consists of a shaft washer, a housing washer and a ball and cage thrust assembly. The bearings are separable so that mounting is simple as the washers and the ball and cage assembly can be mounted separately. Thrust ball bearings, as their name suggests, can accommodate axial loads in one direction and thus locate a shaft axially in one direction. They must not be subjected to any radial load.     

Drawings of crane hooks thrust bearing 51230

Features:
 1. with one-way, two types of two-way.
  2. In order to allow installation error, whether one-way or two-way, you can select the type of spherical self-aligning spherical or spherical saddle seat type.
  3. quality steel - the highest use can extend bearing life 80% of the ultra clean steel.
  4. a high degree of grease technology - NSK grease lubricant technology can extend the life and improve the performance of bearings.
  5. high-grade steel ball - quiet and smooth high-speed rotation.
  6. using options in the ring, may allow installation error.

Application:

Applies only to bear the side of the axial load, low speed parts, such as crane hooks, immediately pump, immediately centrifuge, jack, speed reducer. Shaft bearing ring, seat ring and rolling bodies are separate and can each assembly and disassembly.
