Manufacturer & Supplier of felt wick lubricators
felt wick lubricator


Wick lubricator :
Wick lubricator is made from special quality felt wick where rapid oil transfer woolen wick is embedded in it. This enhances the wicking capabilities and lubrication of felt. Our Wick lubricator delivers a consistent, controlled supply of lubricating oil to machinery bearings or moving parts using capillary action. A wick lubricator in a railway traction motor is a passive lubrication system that continuously feeds oil to the motor's axle suspension or armature bearings via capillary action process. It ensures consistent oil lubrication, filters out contaminants, and prevents bearing failure without requiring complex mechanisms.

Working process of our Wick lubricator :
A reservoir holds a supply of high quality oil , our felt lubricator one end is submerged in the oil and the other end touches the part which needs lubrication. Through Capillary Action properties our Wick lubricator naturally draw the oil upward and continuously transfer it to the friction point.

Key Components:
● Wick Lubricator or Oil Wick pad : Made from High Quality wool felt or specialized felt. It is highly absorbent and draws oil upward from a reservoir.
● Oil Reservoir: A cavity or housing located beneath the bearing or axle cap that holds the oil lubricant.
● Positioning Spring: A mechanism (often a coil or torsion spring) that pushes the wick firmly against the rotating axle or bearing surface.

Advantages and features :
● Automatic & Controllable: The transfer and flow of oil operates automatically as long as the felt wick is touching the oil reservoir filled with oil. The feed rate can be adjusted by changing the size of the wick, adjusting the oil level, or manually raising/lowering the felt wick lubricator.

● Filtration: Our felt wick lubricators are manufctured from Natural Wool fibers which acts as a natural filter, preventing dirt, dust, and contaminants from entering the sensitive bearing.

● Self-Regulating: Oil is transfered and delivered continously at a steady, slow rate, making it ideal for machinery that requires continuous, light lubrication without flooding.

● Oil Retaining: The wick lubricator retains the oil and does not discharge it quickly. It holds and stores for longer period of time.

Application / Uses :
Wick lubricators are highly valued for their simplicity and require no electrical power or complex pumps. They are traditionally found in:

Railroad Locomotives: Our Wick Lubricator pad Assembly is used in Traction Motor of Diesel locomotive engines. Widely used to lubricate train axle journals and traction motor bearings.

Industrial Machinery: Used on horizontal shafts, sleeve bearings, and old-style machine tools.

Electric Motors: Used for the sleeve bearings found in small motors.

In vintage two-stroke marine engines, felt wick lubricator are used primarily in auxiliary drip-feed or siphon oilers for mechanical linkages, governor drives, and small bearing assemblies. They utilize capillary action to pull lubricant from a reservoir and deliver it at a slow, continuous rate. In low-speed two-stroke marine crosshead engines felt wicks are part of the engine’s auxiliary lubrication systems. The felt uses capillary action to draw oil from a reservoir and dispense it at a slow, constant rate. Wick lubricator delivers cylinder oil to slower-moving components, such as the crosshead guide bars or specific control linkage points.

Lubrication of bearing surfaces is maintained by the supply of a constant thin film of oil between the surfaces of the bearing and the shaft. In most bearing applications in steam traction engines and locomotives, a small but constant supply of oil is maintained by the use of traditional wick lubricator which syphons the oil from usually a cup and down a small tube communicating with the bearing surface. Depending on the type of bearing, the type of lubricating oil may differ, with generally a lighter oil for high speed bearings and a thicker oil being used for lower speed shafts.

The Choice of lubricating oil depends on the method of lubrication. It's important to use a genuine high quality wool felt wick lubricator for best performance, thereby ensuring excellent wicking ability. Our wick lubricator can be customised into any shape and size. The number of wick strands will also depend on the size of the lubricator and flow of oil required.

There are generally three types of lubricating cup application:

1) Rotating Bearings, such as Big-End bearings
2) Sliding, such a pistons, Little-End bearings
3) Stationary, such as cup oilers to main shafts and axle bearings

It is very important for wick lubricator to function otherwise without it may damage the steel shaft if no oil is lubricated, which would result in bigger loss.

Maintenance Tip & Best Practices:
Because they operate in heavy-duty and often dusty environments (e.g., freight locomotives and EMUs), wick lubricators require routine inspections, Technicians must routinely monitor the drip rate :
● Glazing: The end of the wick in contact with the rotating shaft can sometimes become glazed (hardened and sealed) by the heat and friction. If this happens, the glazed end must be carefully trimmed off to expose a fresh, absorbent surface.
● Contamination: The wick acts as a filter, meaning it will eventually clog with dust, debris, and metallic particles. Clogged wicks fail to draw oil and must be cleaned or entirely replaced.
● Reservoir Levels: Operators must periodically check the reservoir and top it up to ensure the wick remains submerged in sufficient oil.

If the oil reservoir runs dry, the mechanism will experience metal-to-metal friction and damage the parts.

Wick pad Lubricator Assembly
We are manufacturer of Wick pad Lubricator Assembly for Traction Motor locomotive parts. The wick lubricator are produced from High quality long length wool fibers which are thoroughly checked for quality assurance purpose. We assure highest quality premium grade Wool Wick material & manufacturing by Experience people in advanced machines along with fully equipped measuring and testing facilities, our Quality team checks the product durability and long life. Traction motor is one of the main part behind the complex propulsion systems that runs the Goods and passenger locomotive engines. Lubrication of traction motor suspension bearings is provided by felt wick inserted in the oil reservoir in each bearing cap, which ensure that the quantity of oil required for the lubrication of bearing as available continuously. The oil is drawn up from the oil reservoir to the bearing by capillary attraction in the strands of the felt and it is therefore essential for proper lubrication to provide a continuous path for the oil flow. For the proper lubrication of suspension bearings it is good normal practice that felt wicks are maintained at satisfactory level.
