1 These bearings are made of spring steel. Spring steel annealing temperature is 3500C. Therefore, the annealing temperature of 1800C than ball bearing steel (100C6) of the temperature sensitivity is poor. Material in the temperature reaches above the tempering temperature is extremely losing its hardness. Therefore, spring steel is more suitable for high temperature operation.

2 spring steel has good flexibility, so easy to install, through the help of two inner hook-shaped wrenches mounted in any position, the inner ring of the internal tension that it fits tightly on the shaft. Elastic material processing tolerances h9 or h1l the inner is relatively easy to achieve. That used in the inner ring on the high processing costs can be omitted.

3 Bearing this durable and are subject to dirt, iron, water, and falling iron and the formation of acidic water has little effect. Circle of large diameter thin-walled spiral scroll left large parts of space. These components will be able to scroll down to stolen goods and foreign substances spiral ring spiral cracks. This maintains the movement of the bearing surface in the rotation to keep clean.

4 The main advantage of spiral bearing outer ring can be reused many times, which makes as soon as the temperature due to the impact arising from damage and bending can be re-processed as possible. In this case, bearing is also need to be adjusted. Structural design of such structures, not only the outer whole bearing screw need to be changes, all the rest of the bearing components can be used again. Adjustment of bearing diameter is increasing at a rate of 1 mm for the way. For example: When the diameter increased from 105mm to 106mm, the spiral also need to increase the outer diameter of lmm to install. This situation can be repeated up to 110mm in diameter when. This process can be repeated bearing outer ring 5 times. This cost savings can be substantial; especially bearing in all other parts can be reused six times in the case.
