N and NS Oilers - Wick Feed Oilers

N and NS Vari-Feed Wick Oilers are used to provide a controlled amount of oil to a bearing or other machinery part. The principle of delivery combines gravity feed with capillary action in the wick to provide a constant feed rate of oil regardless of the fill level in the reservoir. Feed rate is determined by the viscosity of the oil and the type of wick being used.

The feed rate is constant and adjustable only by changing to a different wick. Five wick speeds are available and color coded for easy replacement or installation. A multi-pack of different wick speeds is included with each oiler.


Oil Sight Window

An oil sight is available on NS models for visual indication of oil flow.

Additional Features


Copper brazing of all steel connections provides long life and leak proof design. Plastic reservoirs have reinforcing ribs for long life. Zinc plating resists corrosion.

Snap Cap

A dust proof cap keeps lubricant protected.
