Founded in 1990, China Famen Bearing Co., Ltd. is specialized taper roller bearing manufacturer and taper roller bearings distributor of all types of custom and cheap bearings. We obtained ISO9002, ISO14001, and QS9000 certificates in 1995 and 1996, 1999 respectively. Other advanced equipments include four RGB and RCI series heat treatment production lines with a treatment quantity totaling 1,500 kilograms per hour. The Multi-points temperature control meters and CNC display meters with bi-directional control have been adopted to complement these units.

Four row taper roller bearing is one of the main roll bearings , including cylindrical bore and taper bore.
Four row taper roller bearing with cylindrical bore called as TQO. It can take radial load as well as axial load at the same time. It is usually used for four high mills work roll back-up roll and the roller of breaking down mill and beam mill . Usually which work with the axle journal not tightly.
Four row taper roller bearing with taper bore is developing on basis of TQO bearings. The frequent appeared structure is the type of TQITS . Because inner bore have conical degree, so it can work with axis journal tightly , avoiding the squirm on the surface of roller neck .
Compared with TQO, its much more complex in use and pretty difficult in producing . So, it can only use in high speed and high precision roll
We also could supply Four-row Taper Roller Bearings inch series, the inner diameter from 152.400mm---825.500mm

BCA National Taper Roller Bearings are designed to provide constrained relative motion between two rotating parts of the vehicle. These bearings are made from solid steel material which has high resistance to fatigue failure. They also enhance the efficiency and facilitate high speed.
Taper roller bearing mainly can be subject to the combination of radial and axial load. Axial load depends on the outer raceway angle.
