Hot and cold rolling mills operate in some of the most challenging environments in heavy industries, with extreme temperatures, heavy loads, and high-speed operation. Our ZWA Tapered Roller Bearings are specifically designed and produced to work in these severe conditions. Empowering efficient rolling with innovative technology.
The four-row tapered structure enables dual load-bearing in both axial and radial directions, increasing the service life by 40% compared to traditional bearings. It can withstand the high-speed heavy-load impact and the alternating cold and hot environment of the rolling mill. The use of gradient-hardened alloy steel material and nano-scale surface treatment technology reduces the friction coefficient by 18%, and the adaptive sealing system effectively blocks the intrusion of rolling oil dirt. The special raceway modification technology ensures the alignment of the roller system, significantly improving the dimensional accuracy of the sheet and reducing the frequency of unplanned shutdowns.
High rigidity: The four-column design enhances the overall rigidity of the bearing and is suitable for applications requiring high precision and high rigidity.
Long life: Optimized design and high-quality materials enable it to maintain a long service life under harsh conditions.
Easy installation and maintenance: Usually a separable design for easy installation, removal and maintenance.
Good aligning performance: can adapt to a certain shaft and seat hole deflection, reduce the impact of installation errors.
We always adopt the most suitable raw materials, among which case hardened steel plays a main role.
Advanced heat treatment production line from Aichelin set assured the interior chemical organization of the bearing.
Always highest precision level and tailor-made design insured the bearings’ best and stable performance.
ZWA provides intelligent monitoring services throughout the entire life cycle to help customers optimize both bearing performance and equipment capacity. Welcome to inquire about customized rolling mill bearing solutions!
