RENOLIN UNISYN CKC
Polyalphaolefin-Based Industrial Gear and Lubricating Oils Designed for use in industrial gearboxes and general lubricating systems subject to high temperatures, RENOLIN UNISYN CKC oils are fully-synthetic lubricants based on polyalphaolefins. RENOLIN UNISYN CKC oils lower friction and reduce wear. Furthermore, these oils increase the efficiency of machine components. Depending on the application, a number of viscosity grades can be satisfied by a single RENOLIN UNISYN CKC oil. This allows users to rationalize stocks and cut costs. Polyalphaolefins, and thus RENOLIN UNISYN CKC oils, are miscible and compatible with mineral oils at all ratios and can be disposed-of as such. The compatibility of polyalphaolefins with common machinery materials, seals and paint finishes is comparable with that of mineral oils. Changing-over to RENOLIN UNISYN CKC is therefore very simple and requires no prior flushing. RENOLIN UNISYN CKC oils can be classified as CKC lubricating oils according to ISO 6743-6.
The specific benefits of using RENOLIN UNISYN CKC oils are:
- Extremely good ageing resistance
- Excellent corrosion protection
- Good cold-flowing properties
- Excellent viscosity-temperature behaviour
Application:
RENOLIN UNISYN CKC oils can be used in bearings, lubrication systems and gearboxes subject to high or fluctuating temperatures.
In gearboxes and lubricating systems where the sump temperatures exceed 90°C, normal mineral oil change intervals can be significantly extended with RENOLIN UNISYN CKC oils which, in turn, substantially lower operating and disposal costs.
When changing-over to RENOLIN UNISYN CKC oils in machines and equipment which operate at temperatures of over 60°C, one viscosity grade lower than the normal mineral oil grade should be selected.
