For the fan of a living room ventilator an absolutely silent bearing must be found. The bearing must compensate for certain manufacturing tolerances of the injection-moulded housing. The housing has a compact design; only a small installation space is available for the bearing used.
Bearing element LEZ367 with 2.5 mm wire and 6 mm balls.
To further minimize noise, the ball cage of the bearing is only fitted with every second ball. To facilitate series assembly by the customer, the injection-moulded housing has been optimised. A threaded ring is used to adjust the bearing seat.
