MONTON Rolling Mill Bearings include:
1. High Speed Wire Rod Rolling Mill Bearing
High Speed Wire Rod Rolling Mill Bearing are one of the core components in the production of wire rods and bars. High-speed wire mill bearings, such as the four-row tapered roller bearings used in roughing and medium rolling mills, and the double-row cylindrical roller bearings and angular contact ball bearings used in finishing mills, need to adapt to the environment of high speed and heavy load. Due to the impact loads in the work, the impact toughness of the bearings is very high. High-speed wire mill bearings need to be able to operate stably under high speed, high load and high impact conditions, and have a long fatigue life. Due to its special working conditions, the reliability, wear resistance, service life, impact toughness and other requirements of high-speed wire mill bearings are extremely strict, and the processing difficulty is particularly large. The high-speed wire mill production line requires the use of bearings with stable quality and high reliability due to the special working environment.

MONTON Bearing is professional enterprise engaged in the research and manufacturing of oil film bearings for rolling mills. Our company can provide various specifications of oil film bearings to meet the requirements of hot-rolled strip mills, cold-rolled strip mills, and medium thick plate mills for black and non-ferrous metals. We have supplied over 1600 rolling mills. Our domestic market share exceeds 50% and we have exported to over 30 countries and regions.
3. Double lip seal and elastic washer for Wire Rod Blocks
Double lip seal and elastic washer for Wire Rod Blocks also called damping washer. High-speed wire mill thrust bearings are equipped with elastic washer when installed, and preload is required during installation. This Damping gasket can effectively solve the clearance problem of the bearing during operation. If the clearance of bearings too small, they may get stuck or the temperature rises, while if the clearance is too large, it will cause vibration. Adding damping gasket can eliminate vibration and avoid damage to the bearing due to too small clearance, which not only improves the working accuracy of the bearing, but also increases the life of the bearing.
4. Sendzimir Bearings
Sendzimir Bearings are also called back up roller bearing. They are used in multi-roll cold rolling mills and can also be used in straightening or bending machines. This type of bearing has a particularly thick outer ring and can be mounted on a fixed support shaft to form a support roll or straightening roll. When used, it is mounted in groups on a stationary shaft to form a support roll. The pressure on the working roll is transmitted to the support roll through the intermediate roll and to the frame through the saddle system. Sendzimir bearings are generally designed with two or three rows of rollers, with cages or full rollers (without cages). Its advantages are simple geometry and high radial load capacity. Backing bearings without flanges or movable retaining rings cannot withstand axial loads by themselves, so this type of bearing must use thrust washers made of copper or engineering plastics, which are installed between the end face of the outer ring and the saddle. This also applies to back up bearings in the form of needle rollers.
5. Four-row Cylindrical Roller Bearings
Four-row cylindrical roller bearings are mainly used in roll necks, including support rolls, intermediate rolls and work rolls, rolling stands, calenders and roller presses in plate, long product and section mills. These bearings are usually mounted on the roll neck with an interference fit. Four-row cylindrical roller bearings are well suited for rolling mill applications with high rolling speeds.
Four-row cylindrical roller bearings can only carry radial loads. They are mounted together with deep groove ball bearing or angular contact ball bearings, or with tapered roller bearings that carry axial loads.
6. Four-row Tapered Roller Bearings
The performance of four-row tapered roller bearings is basically the same as that of double-row tapered roller bearings, but the radial load is greater than that of double-row tapered roller bearings, and the limiting speed is slightly lower. It is mainly used in heavy machinery, rolling mills, etc. Four-row tapered roller bearings are suitable for low-speed and medium-speed rolling mills. The internal clearance of the bearings is pre-adjusted, easy to use, and designed to withstand the maximum rated load in a limited installation space. Four-row tapered roller bearings (open type) are include three outer rings, two inner rings, four rows rollers, two outer spacers, and one inner spacer. Sealed bearings are added with two sealing rings. The clearance of four-row tapered roller bearings can be adjusted with two outer spacers and one inner spacer. This ensures the rotation accuracy and normal operation of the machine parts, and greatly extends the service life of the bearings.
7. Spring bushing bearings
Spring bushing bearings are mainly used in continuous casting machines. Spring bushing bearings mainly include inner and outer rings of a helical spring structure, rolling elements, cages, end covers, and outer shells of the outer rings. The two ends of the shells fit the end covers, and there is a gap between the shells and the outer rings. A journal is provided on the inner side of the inner ring, and a circular left sealing plate and a right sealing plate are provided on the journals. During processing, the bearings undergo rolling, annealing, quenching, high-temperature tempering, shaping, cutting off the spiral tails of the inner and outer rings, and outer diameter grinding. Since the inner and outer rings are helical spring bodies, temperature changes allow the inner and outer rings to freely expand and contract in the axial and radial directions, so they will not get stuck during work. The gaps in the inner and outer rings of the helical spring bodies can store grease and foreign matter, which is conducive to lubrication and removal of foreign matter, and is beneficial to increasing the life of the bearing. The helical spring body makes the bearing elastic, they can withstand impact resistance, and maintain normal operation under flexural deformation.
8. CARB toroidal roller bearings
CARB toroidal roller bearings have one row of long, slightly barrel-shaped symmetrical rollers and torus-shaped raceway profiles . They are non-locating bearings and accommodate exclusively radial loads. CARB bearings are often used to replace the non-locating spherical roller bearing in a locating/non-locating bearing arrangement. Bearing features：Accommodate misalignment，Accommodate axial displacement，Wide assortment of dimension series， Long service life， Low friction，Improved wear resistance，Low noise advantage.
9. High speed wire rod mill guide bearing
The high speed wire rod mill guide bearing produced by MONON is a type of bearing used on the rolling mill guide wheel for guiding the wire forward on steel rolling wire equipment. Common models include 6200-ZTN9/LT and 6202-ZTN9/LT, mainly used for the guide wheel of high speed wire in steel rolling mill. The commonly designed of the guide bearing is deep groove ball bearing structure, which adopts optimize structure sealing and has the characteristics of low noise and high speed.
