What are the advantages of NAF crossed roller bearings compared to traditional bearings?
It is characterized in that the cylindrical roller moves in straight alignment on the rolling surface of the 90-degree V-shaped groove through the gasket. Therefore, crossed roller bearings can accept multi-directional loads such as radial loads, axial loads, and torque loads. Compared with the combination of traditional thrust bearing and radial centering bearing, the crossed roller bearing has a compact structure and small volume, which simplifies the design of the worktable, thereby reducing the cost of the turntable.
With the design of rows of crossed rollers, the effective management span of the bearing can be significantly improved, so it has a high anti-overturning moment for this type of bearing. In crossed roller bearings, it is divided into the following two different types: the first is crossed cylindrical roller bearings, and the second is crossed tapered roller bearings.
The price of horizontal cylindrical roller bearings is generally lower than that of horizontal tapered roller bearings, and it is suitable for use on turntables with relatively low speed; Small, lower processing costs. Crossed roller bearings are suitable for various types of vertical or horizontal drilling machines, and are suitable for use in vertical grinding machines, vertical trucks and large gear milling machines, etc.
Although the process of specially producing and adding crossed roller bearings is cumbersome, it has certain requirements for operators. Relying on the advantages of new equipment, it can quickly form mass production capacity, quickly increase the production cycle, and significantly reduce the cost compared with turntable bearings. For users, its cost performance is much higher than that of conventional bearings. This is also the main reason why crossed roller bearings have gradually replaced traditional bearings in recent years.
