Lubricants & Greases
Lubricants & Greases
Greases are higher viscosity, semi-solid materials, with thickeners to hold the grease in place which allows for long term, harsh-condition lubrication. Liquid lubricants do not typically contain thickening materials like greases, allowing them to be a less viscous, flow-able liquid.Types are;
LA and LB: chassis lubricants (suitability up to mild and severe duty respectively)
GA, GB and GC: wheel-bearings (suitability up to mild, moderate and severe duty respectively)
Silicone grease
Fluoroether-based grease
Laboratory grease
Food grade grease
Water-soluble grease analogs
Cork grease
mineral oil
Synthetic oils
solid lubricants
aqueous lubrication
Biolubricant
A good lubricant generally possesses the following characteristics:
A high boiling point and low freezing point (in order to stay liquid within a wide range of temperature)
A high viscosity index
thermal stability
hydraulic stability
demulsibility
Corrosion prevention
A high resistance to oxidation
