011.20.250  Belong to four point contact ball slewing bearing with external teeth,

We had offered the bearing 011.20.250 to our Europen customer ,Now We will introduce  Slewing bearing 011.20.250 specification as follows:

011.20.250 Slewing bearing external teeth parameter as follows:

011.20.250   slewing ring application:

 Power Plants, Cement and Mining industry. Making use of top-grade components,

Stacker Handling Equipment,Reclaimer Machine,Grab.

 011.20.250  Slewing bearing selection:

JinHang Precision slewing bearing are allocated critical load curves for their static load capacity.when defining the required bearing load capacity, the determined loads must be multiplied by the “load factors” according to the work condition.

011.20.250  slewing bearing transport and storage:

Slewing bearing required careful handing

Slewing bearing should always be transported and stored in horizontal position and be stored in dry roofed areas.

USE eyebolts for horizontal handling,Impact,particularly in radical direction,must be avoided.

The surface of slewing bearing should be applied with anti-corrosion oil,and the anti-corrosion period is 6 months,longer storage(as backup,for example) periods will require special perservation

 Material and heat treatment

The Company selects the most suitable materials to manufacture slewing bearings to adapt to

foreseeable purposes. These materials are manufactured by a recognized steel plant. To ensure

product quality, every step in the process is inspected. Tempering heat treatment is needed when

the product is subject to high stres s.

Customers can select mater ials from the following tables. Composition of two materials and

two heat treatment states: 50MnZ, 50MnT, 42CrMoZ, 42CrMoT, with mechanical performance

ranking from low to high. Customers can also specify other materials designations according to

their needs .
