FUCHS RENOLIN
UNISYN CLP 320

RENOLIN UNISYN CLP oils have good resistance to micropitting, and reliable lubrication of roller bearings is confirmed by the good results of the FE8 testing. The required failure load stages in the standard and intensified FZG test are reliably received, and the oils show good filterability.

They are preferably used when increased requirements are set for high and low temperature usage limits. Due to the low pourpoint and the high viscosity index, very good cold flow properties at cold start as well as a high lubrication film thickness at operating temperatures are possible. In gearboxes and circulating systems with sump temperatures up to 90 °C, longer oil-change intervals in comparison with previous mineral oils are achieved.

Highly-stressed bearings, joints, pressure screws, spur gears, worm gears and planetary gears can be supplied even at short-term peak temperatures up to 150 °C. Miscibility with gearbox oils based on mineral oil and ester is generally given, which means a simplified change-over is possible.

FUCHS states the products meet and, in many cases, exceed the requirements according to:

• DIN 51517-3: CLP
• ISO 6743-6 and ISO 12925-1: CKC / CKD / CKE / CKSMP
• AGMA 9005/E02: EP
• AIST 224
• David Brown S1 53.101
• FAG-FE8 test: stages 1-4 pass (test report available for ISO VG 320)
• SKF requirements: pass (100 °C test)

• Low foaming
• Good air release capacity
• Very good aging resistance
• Excellent corrosion protection
• Excellent viscosity-temperature behaviour
• High natural viscosity index, multigrade character
• Excellent wear protection, high EP performance
• Very good filterability
• Miscible with mineral oil- and ester-based gear oils
• Lifetime lubrication possible
• For high and low operating temperatures

FUCHS lists RENOLIN UNISYN CLP 320 among the gear oils it offers for wind turbine main gearboxes, and the product page for the series names power generation among its industries. FUCHS also notes that low foaming, good air release and good filterability matter for gearbox lubrication, and that excellent low temperature flow helps reduce wear at cold start.
