WAL deep groove ball bearings are used to balance the various expansions of bearings and housings.
In order to avoid damage to the polyamide rings, the housing bore is fitted with a chamfer of 15° - 30°. It is recommended to use the drilling tolerances G6 or G7.
Due to the polyamide rings (service temperature range -20°C to +110°C) on the outer ring, a circumferential movement of the bearing in the housing is prevented at elevated temperatures.
Tolerances according to DIN 620, tolerance class PN.
