For the slewing ring manufacture, ROLLIX selects the best material specifications to suit most foreseen usages.
These materials are manufactured by approved steel works.
Inspections are carried out at each significant step of manufacturing what makes it possible to warrant the quality of the products. Most of the time, we select high-grade Carbon steels which permit us to meet all operating requirements.
Core hardening and tempering are carried out when the applied stresses dictate these processes.

COMPONENTS 

ROLLIX selects rolling elements : balls and rollers with very specific characteristics.
Their assembly requires particular caution.
Any action of dismantling bearings or replacement of rolling elements is definitely inadvisable and cancels the ROLLIX warranty.


OTHER MATERIALS
Specific factors of some applications or functional requirements may result in the use of materials such as :
. Stainless steel.
. Structural hardening steels or alloys.
. Special steels for hardening under controlled atmosphere.
. Case or nitrided steel.
. Special steels for very low temperature.
. Aluminium-based alloys.
. Titanium alloys.
. Plastic, composite materials.
