RENOLIN CKCHigh Performance CKC Gear Oils High Performance CKC Gear Oils
Gearboxes designed for the transfer of power or torque can only perform effectively when excessive wear which can occur at high or fluctuating loads, particularly around the reference circle, is avoided. The life of a gearbox depends on the correct selection of the most suitable lubricating oil. The principal function of a gear oil is not just to lubricate bearings and the gears themselves, i.e. to reduce friction and avoid wear but also to provide protection against corrosion, to cool and to seal. The RENOLIN CKC gear oils contain carefully selected base oils and matched additives to protect machinery from undue wear in especially critical boundary friction conditions. RENOLIN CKC products can be classified as CKC lubricating oils according to ISO 6743-6.
The special characteristics of RENOLIN CKC series lubricants are:
- High pressure absorption and excellent wear protection
- Good viscosity-temperature behaviour and excellent low-temperature characteristics
- Good corrosion protection for steel and nonferrous metals
- Good resistance to ageing
- Good compatibility with sealing materials
- Low foaming
- Avoidance of frictional vibration by the use of surface-active additives
- Good demulsification characteristics
- Multipurpose applications
Application:
RENOLIN CKC series oils are recommended for all industrial applications where the machinery manufacturer recommends the use of a CKC type oil. Highly-stressed bearings, joints, pressure spindles, spur and worm drive gears are reliably, effectively and economically lubricated at temperatures of up to 120°C. The use of these oils guarantees the quiet and smooth running of machinery along with optimum operational reliability. The use of these oils also allows drain intervals to be extended. Please consult our Application Engineers for suggestions on how this series of oils can be used to rationalize oil stocks.
