An oil dispenser is a watchmaker's and precision mechanic's aid for introducing lubricating oil into a bearing .

It is usually a ( steel ) wire with a small diameter (0.15–1.00 mm), which is equipped with a lanceolate tip (comparable to the leaf of a willow ). The oil dispenser is usually provided with a handle for better handling.

The oil dispenser is immersed in the oil to be introduced and pulled out. Depending on the diameter of the oil sender, the oil, the immersion depth and the speed at which the oil sender is pulled out of the oil, a more or less large amount of oil will remain on the oil sender (until drops form). This amount of oil is released to the bearing by capillary force when the bearing gap comes into contact with the oil dispenser. The oil quantities can be kept extremely low, depending on the bearing.

With the automatic oil dispenser, a thin wire running in a cannula dispenses a dosed amount of oil at the push of a button. This was developed and patented by the company “Büren Watch Co.” in Switzerland in 1947 and produced by the company “Bergeon” .
