BASIC CONSTRUCTION of a Slewing Bearing

MATERIALS

For the slewing ring manufacture, SoCare® 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 alloy steels 42CrMo4 which permit us to meet all operating requirements.

Core hardening and tempering are carried out when the applied stresses dictate these processes. 

COMPONENTS

SoCare® 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 SoCare® warranty

HEAT TREATMENTS

The slewing ring transmits loads from a turning part towards the fixed part of a mechanism. The applied stresses of the rolling elements on the raceways are calculated according tothe modern criteria of plasticity.

SoCare® carries out localized hardening treatments which makes it possible to satisfy these criteria just as well in terms of surface pressure as well as subsurface fatigue.

In all cases, induction or flame hardening permits us to achieve the necessary hardness patterns and a sufficient depth simultaneously.

In process systematic inspections during production enable us to warrant the quality and the reliability of the slewing ring treatment, according to SoCare® specifications.

According to the level of applied stresses and if geometry allows it, the same kind of hardening process may be applied on gear teeth. 

Our calculation models allow us to select the kind of treatment required.Other processes of local hardening may also be provided, for example : case hardening, nitriding, etc.
