Nyoil is the only internally lubricated nylon available in three grades tailored to specific applications: Standard Green NYLOIL for most anti-friction applications. Natural color NYLOIL-FG, the only FDA and USDA compliant lubricant filled nylon for food contact, affords designers of food processing and related equipment a bearing option not previously available. Gray NYLOIL-MDX, a molybdenum disulfide filled and internally lubricated cast nylon, combines lubricant properties with higher physical strength for applications demanding higher loadings.

Ordinary cast nylon significantly outlasts cast iron, brass, bronze and many other metallic and non-metallic bearing materials, however, NYLOIL provides identical reliability to ordinary cast nylon, and offers superior notched load impact, elongation, coefficient of friction, PV capability of 16,000, and reduced water absorption.

Product Applications

• Bearings
• Bushings

• Seals
• Sprockets
• Wear Pads

Typical Properties

A lubricated surface at all times

• During NYLOIL's manufacturing process, oil lubrication is completely and evenly dispersed throughout the cast nylon, making it an integral part of the material's structure. Although not evident by sight or touch, the oil lubricant in NYLOIL is always at the surface, regardless of the amount of material removed during any finish machining operations.
• Oil will not spin out, dry out or drain out, even under harsh working conditions.
• Lubrication results in 25% lower coefficient of friction than conventional grades of nylon.
• Lower coefficient of friction means less frictional heat buildup, the major cause of plastic bearing failures.

Proven tough in harsh environments

• NYLOIL typically lasts 5 to 7 times longer than unlubricated or MoS2 dry lubricated cast nylon. This durability makes NYLOIL an excellent choice for applications where traditional materials, including ordinary nylon, cannot be used.
• Performs in harsh environments where lubrication is difficult or impossible, or where constant lubrication is required.

Additional Features

• Can be run without additional lubrication
• Works efficiently in marine applications
• Does not require bearing seals
• Constant lubrication results in low heat build-up

Works and machines as easily as brass

• The long lasting properties of NYLOIL come with no penalty in machinability. It can be free cut, and requires no more machining skill than ordinary nylons. Because it contains its own lubricant, NYLOIL can be machined much more quickly and easily than unlubricated nylon. Obtain excellent surface finish by using sharp tools in turning, milling, shaping or any other machining methods.
• For conventional finish machine operations, use any high-speed machine tool or woodworking equipment including circular saws, planing and routing machines. Machining operations will not affect NYLOIL's self-lubricating qualities.

Wear Rate

Adding a lubricant to the basic polymer during the manufacturing process reduces the coefficient of friction by 25% at the bearing interfaces, thereby avoiding harmful heat build-up that limits the wear life of unlubricated materials. The PV capability of NYLOIL without lubrication is approximately 16,000.

Dimensional Stability

With their higher crystallinity, all Nycast® products exhibit improved dimensional stability compared to their extruded nylon counterparts. But NYLOIL provides even better dimensional stability than regular grades of cast nylon. Its oil droplets fill gaps in the amorphous structure of the polymer, allowing less room for water to be absorbed into these areas. The moisture absorption graph shows that despite a slow absorption rate, NYLOIL stabilizes at approximately 2.5% moisture content - less than half the moisture content of other unfilled nylons.
