Typical Applications

 N/A
  • High-speed precision machine tool spindles
  • Low-viscosity, low-pressure hydraulics

Proprietary Additive

 N/A LE’s proprietary additives are used exclusively in LE lubricants. Monolec Spindle Oil contains Monolec.

Monolec® wear-reducing additive creates a single molecular lubricating film on metal surfaces, vastly increasing oil film strength without affecting clearances. An invaluable component in LE’s engine oils, industrial oils and many of its other lubricants, Monolec allows opposing surfaces to slide by one another, greatly reducing friction, heat and wear.
