Ball Bearing EPL2 

Ball Bearing EPL2

Castrol Spheerol™ EPL is a range of greases which comprises lithium based products, containing highly refined mineral oils, fortified with extreme pressure (EP) additives as well as corrosion and oxidation

inhibitors.These greases have been formulated with additives that provide good film strength under medium to high loads.

The Spheerol EPL range comprises general purpose greases designed for plant wide lubrication. The range extends from a NLGI 3 for general purpose bearing lubrication to a NLGI 00 (see separate data

sheet) semi-fluid grease suitable for centralised lubrication systems and grease filled gearboxes. These greases provide good protection against rust and corrosion as well as resistance to water wash-out; which makes them particularly suitable for equipment where moist or wet conditions are common.

 

The stiffer consistency afforded by an NLGI 3 grade makes this product particularly suitable for the lubrication of bearings that are vertically mounted, or components exposed to a high degree of

vibration. The good levels of resistance to both corrosion and water wash-out, which makes this product suitable for equipment where moist or wet conditions are common.

Advantages

High mechanical stability – the grease keeps its consistency in service ensuring long lubricant life
Good adhesion – continuous lubrication and reduced consumption as film stays between lubricated surfaces
Good water resistance – the grease film remains on the surface even in the presence of water
Resistant to copper and steel corrosion – helps prevent rust and oxidation on metal surfaces
Excellent EP and anti-wear properties – protects equipment against extreme loading and helps minimise bearing component wear
