A company in Jiangyin has two cold rolling mills, which are the United States I2S 1400 double flattening and 1400 single frame cold rolling mill. The rolling mill has high speed and large rolling force.
Its support roller type bearing is TIMKEN - TQITS four row tapered roller bearing.
TQITS bearings
Developed for high-speed rolling mill roll-neck applications, these four-row tapered roller bearings are supplied with a tapered-bore bearing to minimize neck wear.
The bearing characteristics of inner hole with a taper and taper roller diameter can achieve interference fit, has reached the purpose of high-speed operation, its structure is more complex: the two single inner ring, a pair of inner and outer ring and four single three outer spacer, four row tapered rolling body, the four column is the holder a total of 18 parts. It is difficult to design and manufacture.
After the failure of the localization of a company, FV customized 4 sets of 1400 sets of double roll flatness BUR bearings. It has been in good operation since 2016-6-12 days.
BUR bearing site of 1400 light machine.
