Semi-Synthetic Slideway, Chain and Gear Oils
 
 
 

AMSOIL Semi-Synthetic WL Series Slideway, Chain and Gear Oils

Designed specifically for extreme pressure (EP) machine tool slideway applications. Its unique composition makes it multi-purpose, and perfectly suited for industrial chain and gear applications.

PRODUCT DESCRIPTION

AMSOIL Semi-Synthetic WL Series is a high-quality, heavy duty lubricant composed of synthetic base oils, large molecule petroleum base oils and additives specifically designed for EP applications found in gear, chain and machine tool applications. This combination of base oils and EP additives provides the excellent lubricity and film strength needed to prevent scoring and wear during equipment operations. By incorporating synthetic base oils, AMSOIL WL Oils reduce friction for good overall performance.

Machine Tool Slideways

AMSOIL formulated the WL Series with additives designed to prevent the stick/slip or chatter phenomena that commonly occur at the beginning and end of a machine tool stroke. This happens because the lubricant and additives are squeezed out during boundary lubrication conditions. Metal to metal contact then occurs, also causing wear to the slideways. AMSOIL uses EP additives that form a hard boundary layer of protection and tackifying agents that improve the adhesion properties of the oil. These additives prevent stick/slip and wear. Additionally, the WL Oils are anti-rust fortified and have excellent resistance to water washout. This is important since emulsified cutting fluids are commonly used and components are generally exposed to the environment.

Chain and Gear Lubrication

The performance characteristics of the WL Series make them ideal for chain and gear applications. These oils are friction-reducing, compatible with seals and paints and are resistant to water. The tackifier agents used ensure the components have constant lubrication, allowing the EP additives to prevent rust. The semi-synthetic nature of the WL Oils delivers excellent performance in a wide variety of environments.

Performance Features

  • Tackified for excellent adhesion and water resistance.
  • Rust and corrosion inhibited.
  • EP additives prevent stick/slip and slideway scoring
  • Semi-synthetic adds lubricity and reduces friction.
  • Recommended for slideways, chains and EP gear applications.

Application Recommendation

AMSOIL WL Series Oils are recommended for use on machine tools where mating surfaces operate under heavy loads and slow speeds. Some applications include the plain bearing slideways of lathes, shapers, grinders and milling machines plus the slideways of saws and carraiges found in lumber mills. AMSOIL WL Oils are recommended for use on open or enclosed chain drives and in EP gear box applications where tackified EP gear oils are recommended or where they do not pose a problem.

Chain and Gear Lubrication:  

Do not use the WL Oils on yellow metal or worm gear applications operating at or above 200 F.
