TRICO NO-4 Vari-Feed Wick Oiler

Description:

The Trico NO-4 Vari-Feed Wick Oiler is used in industrial lubrication systems to provide a controlled gravity-fed oil supply to bearings and other rotating machine components through a capillary wick. Commonly installed on electric motors, conveyors, pumps, gearboxes, machine tools, and production equipment where continuous, low-volume lubrication is required. Maintenance teams and system integrators use this part for wick oiler replacement, lubrication system upgrades, preventive maintenance, and improving equipment reliability.

Applications:

The Trico NO-4 Vari-Feed Wick Oiler is commonly used in manufacturing plants, paper mills, steel mills, mining operations, power generation facilities, and general industrial machinery where a constant, metered oil supply helps reduce bearing wear, extend equipment life, and minimize maintenance requirements. Vari-Feed wick oilers provide a consistent feed rate based on wick selection and lubricant viscosity.
