Bearing seal from SKF, Great Plains collaboration reduces downtime
19 May 2021
SKF and its Peer brand engineered new seal to withstand harsh agricultural conditions.
SKF, a supplier of bearings, seals, lubricants, and condition monitoring systems, said it worked in partnership with Great Plains Mfg., a manufacturer of pull-type agricultural implements, to create a new seven-lip seal package to prolong the life of agricultural tillage equipment.

Great Plains Ag, a division of Great Plains Mfg., develops tillage equipment for seedbed preparation. In the Black Earth Region of Russia, key bearings critical to the operation of tilling equipment were wearing out halfway through the growing season. During analysis by SKF and Great Plains engineering teams, significant dirt pack intrusion was found to be a common issue impacting the function of the bearings and leading to machine downtime.
In response, Great Plains and SKF engineers worked to update the machinery’s design to include a more robust bearing seal that would help better prevent dirt pack-related failures. SKF in the U.S. developed a seven-lip seal by redesigning the seal package to help eliminate dirt pack between the bearing, housing and spool, which outperformed the existing seal design. By minimizing the pressure from the dirt pack against the seals, said SKF, the equipment can operate more effectively for a longer life cycle.
“Our long partnership with Great Plains led to this successful collaboration to develop an agricultural bearing that can withstand some of the most extreme climate challenges found around the globe. It’s a great development for the agricultural community, as it creates a more durable, longer lasting bearing, which extends the availability of the equipment, and increases uptime in the field,” said Chris Larson, strategic account manager for SKF USA, Lansdale, Pa.
In addition to retrofitting older tilling machinery models with the newly redesigned seven-lip TILLXTREME seal, Great Plains also included the TILLXTREME seal on its new Great Plains hybrid tillage solution, the Terra-Max, when it launched in September of 2020. Initial in-field testing has been positive, said SKF, earning high marks from the farmer and outperforming all the customer’s goals for uptime and availability.

“Working with our long-time partner SKF Group on this specific challenge, led to a collaborative solution that enabled a better, longer-lasting product for all our customers globally.” said Rodney Hake, engineering manager for Great Plains, Salina, Kan. “Our new Terra-Max tillage line-up leaves a uniform, unrestricted soil profile that promotes maximum root development and increases yields for farmers working in the world’s most challenging areas.
A Kubota company, Great Plains manufacturers grain drills as well as tillage equipment, fertilizer applicators, sprayers and planters.
