Keestrack standardizes long-lasting grease on select scalpers
Keestrack has decided to standardize its Long Life grease (LLG) on the K3, K4, and K5 scalper in their Czech factory as of the start of September 2023, due to great testing results since 2021. Keestrack says that this standardization is intended to increase uptime.
Keestrack's LLG contains anti-wear and anti-friction additives and is resistant to water and rust. It extends service intervals and lowers costs and downtime. It expands the lifetime of the bearings of the screen box and apron feeder by running at a lower temperature. The grease is resistant to high-impact loads and vibrations and can handle an ambient temperature from -25 degrees Celsius to +145 degrees Celsius.
Service interval
Due to the LLG, the service interval is five to 10 times longer, compared to standard EP2 grease. For example: greasing the screen box has been reduced from every 50 hours to every 500 hours.
Operating temperature
The operating temperature of the bearings is much lower with LLG compared to standard EP2 grease. In one test, comparing the EP2 grease versus LLG on the screen box of a K5 scalper, the bearings were running at an operating temperature of up to 60 degrees Celsius with standard EP2 grease, while with long-life grease they were running at an operational temperature of 43 degrees Celsius.
The use of LLG has a positive effect on the lifespan of the bearings, resulting in more uptime, less downtime, and lower costs.
Private label
To emphasize the characteristics of this grease, the cartridges are branded under the Keestrack private label.
LLG is available in 400 ml tubes and can be easily applied by a hand pump. The cartridges are made with a screwable cap so they cannot be mixed up with other classic grease pumps. Operators can apply the grease by the hand pump single-handed or both-handed. The hand pump is designed so that operators can always clearly identify the LLG. At the bottom, it will stay clearly visible at all times.
Keestrack dealers will inform users of this new standard on the K3, K4, and K5 scalpers, incorporated in Keestrack's factories in the Czech Republic as of September 1, 2023. Due to standardizing the long-life grease, the central greasing option on the K3, K4, and K5 will disappear, as this does not make sense anymore because only six bearings have to be greased every 500 hours. The greasing nipples are well indicated by the green labels on the machine with clear instructions.
