• Reduction of fretting corrosion providing easier dismounting of bearings

• Better sliding on designed loose bearing arrangements such as vibrating screens, truck and car wheel bearings

• Easier removal of general industrial components in a wide range of applications such as nuts, bolts, flanges, studs, bearings, guide pins, couplings, jack screws, lathe centres, push rods, and spline shafts

What is fretting corrosion?
Fretting corrosion is a progressive surface damage that occurs in the contact area of two metals. It is caused by very slight oscillations, vibrations or slip between the metal surfaces. Fretting corrosion is a risk for bearings and it typically occurs in the loose fit between the outer ring and the housing or between the inner ring and shaft. Uneven bearing seats and too loose fits can increase fretting corrosion. Repairing corrosion damages requires overhauling of the contact area and poses further risks of improper bearing seating. Fretting corrosion is also a risk for other metal contact areas for example yokes and core of SKF Induction Heaters and SKF Vibracon.

SKF LGAF 3E is a greasy, smooth paste with special additives to form a protective layer between the metal surfaces and reduce fretting corrosion in these and more applications.
