The raceway gap in Franke rolling bearings serves as a compensation zone. The gap compensates for material expansion of the housing parts due to temperature fluctuations, for example.
It also compensates for certain tolerances in the machining of the wire bed as well as distortions and vibrations.
The raceway gap in wire race bearings is the distance between the outer ring of the bearing and the wire that is used as the rolling element in the bearing. This gap is important for the function of the bearing as it ensures that the wire can rotate freely and support the loads that are transferred to the bearing.
The raceway gap must be carefully controlled during the manufacture of wire race bearings to ensure that it is within the permissible tolerances. Too large a gap can lead to instability and uneven load distribution, while too small a gap can lead to increased friction, overheating and premature wear of the bearing.
The raceway gap can be measured and controlled in various ways, including optical and tactile measurement methods. During the production of wire race bearings, special machines are used to keep the gap between the outer ring and the wire at the correct size.
Accurate control of the raceway gap is critical to the performance and life of wire race bearings. Therefore, high quality standards should be maintained in the manufacture of wire race bearings to ensure that the gap is within the required tolerances and that the bearing can operate reliably and effectively.
