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.
