JTEKT has successfully developed the 'Sealing Seal for Steel Mill Drive Shafts' with a higher sealing performance, thus improving the performance of the mill roll drive shaft.
Iron and steel equipment has long been exposed to harsh environments such as high temperatures and is subject to water and iron fouling (iron oxide film produced during processing of high-temperature iron), and therefore, the oil seal used as a main part of a rolling mill drive shaft Working in harsh environments requires higher performance.
The newly developed oil seal products, the use of new materials and shapes, with a higher seal, can extend the oil seal and the entire cross-bearing life, reduce maintenance costs.

'Development Purpose'
'Characteristics'
(1) material replacement
· In the 90 ℃ high temperature environment invaded by the mill water, the permanent stretch of the oil seal is reduced by 50% than the current product (the sealing is improved)
(2) changes in shape
· The contact of the lip side of the oil seal is changed into the radial contact by the thrust contact, which improves the sealing performance when the shaft is shaken.
Endurance test no water inside the bearing
· The force of the lip is 80% lower than the current product
* Urgency: The oil seal tightens the force exerted on the shaft
⇒ By the above two points of improvement, can effectively improve the oil seal, cross-bearing life
· Effectively suppress the sudden damage caused by the cruciform bearings due to deterioration of lubricity
· Reduce maintenance costs for our customers and increase productivity
KTEO, a bearing brand of JTEKT, takes the concept of "Key of your operation" as a product concept and works with customers to solve problems. As a reliable partner, Koyo, a steel manufacturer, To contribute to the development.
