Tension leveler back-up roller BUR63.5 119 for our Indian customer
Back-up bearing BUR63.5 119 for tension levelling lines
The bearings for tension leveler machine are considered back-up bearings/back-up rollers. If compared to the ones used in the flattening machines, these back-up bearings must bear very high speed.

Support roller/Yoke type track roller NNTR65X160X75-2ZL ready for delivery
The full complement roller set support roller, yoke type track roller NNTR65X160X75-2ZL can support very high radial loads and continious axial loads due two its double-row design. Due to the profiled outer surface of the outer ring, it can compensate for axial loads from minor misalignments and skews.
Features
1. Based on full complement, double row cylindrical roller bearing; the two rows of rollers are guided separately from each other by the three ribs of the outer ring; two loose flange rings are used for axial support.
2. Since the bearing does not have a cage, it is particularly stable due to the highest possible number of rolling elements and supports very high radial loads, in addition, the space between the roller sets, which is filled with grease, reduces friction, so relatively high, aslo constantly acting axial loads due to slight misalignment defects or skew, can be accommodated.
3. With inner ring, can be used if the surface of the shaft is not suitable as a raceway.
4. With axial guidance.
5. The axial guidance is effected with the central rib and the rolling elements.
6. Seal: sealing shields with lamellar ring on both sides for high sealing effect.

The advantages of high precision cross roller bearings
The characteristic of high precision cross roller bearing is that cylindrical rollers are vertically aligned with each other and move quickly on the V-shaped groove rolling surface at 90 °. Therefore, the cross roller bearings can bear multi-direction load such as radial load, axial load and moment load. Compared with the traditional thrust bearing + radial centering bearing combination, the cross roller bearing has a compact structure, small size, and simplified the design of the worktable, thereby reducing the cost of the turntable. 
In addition, due to the use of optimized preload, this type of bearing has a high stiffness, so the rigidity and accuracy of the turntable are also guaranteed. Thanks to the design of two rows of cross rollers, this type of bearing has a high resistance to overturning moment. There are two types of cross roller bearings: one is a cross cylindrical roller bearing, and the other is a cross tapered roller bearing.
Although the structure of the cross roller bearing is special, the production process is relatively complicated, and it has certain requirements for the operating staff. But for users, cross roller bearings are more cost-effective than the traditional bearings, which is the main reason why cross roller bearing has gradually replaced traditional bearings in recent years.
