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 bearing reference pictures:

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 .

Standard grad e As-normalized conditio n As quenched conditio n

50Mn Code Z Code T

42CrMo Code Z

How to choose the 011.20.250 Slewing bearing suit for the equipment?

1. axis of rotation: horizontal or vertical or mutual

2. Bearing under:compression or tension

3. Gear :external or internal or without

4. Movement:positioning only or intermittent rotation or continuous rotation

5. No.of the revolution (rpm): normal and maximum

6. Bearing load: axial load and radial load and tilting moment

7. Working time

We can design the assembly drawing according to the customer supply the bearing working condition.Also they can calculate the load curve for customer.
