Lubricant for high temperatures
First Quarter 2021
Other technologies
Lubrication Engineers (LE) has developed the 1250 Almasol High Temperature Lubricant, which has one of the highest temperature capabilities of any grease thickener available in the industry. It is designed to withstand extremely high temperatures, while staying in place to provide constant lubrication. It also resists oxidation and vaporisation, ensuring longer lubrication intervals and fewer bearing failures, thereby protecting equipment, improving performance, and saving on maintenance and repair costs.
It uses a base oil with a heavy viscosity and high flashpoint, as well as a high natural viscosity index. The high temperature clay thickener has a high dropping point, making it ideal for applications such as asphalt plants, brick/ceramic kilns, exhaust fans, kiln car bearings, lime kilns, oven conveyors, pellet mills and plastics. Almasol is the solid wear-reducing additive in the product, which is able to withstand extremely heavy loads, chemical attack and temperatures up to 1038°C.
The maximum useful lifetime for a grease in high temperature bearings depends on many factors, from temperature to the size and speed of the bearings, the amount of oxygen available to the grease in the bearing, the load on the bearing and the degree of external contamination. The approximate maximum useful lifetime guidelines for LE’s 1250 Almasol High Temperature Lubricant are 10 000 hours at 93°C, 100 hours at 149°C and between one and four hours at 204°C.
