Sprial Roller Bearing 5209

spiral roller bearing the advantages of
 A ) this kind of bearing is made of spring steel. The annealing temperature of spring steel 3500C. Therefore, it is the annealing temperature of ball bearing steel 1800C ( 100C6 ) temperature sensitivity difference. Materials reach the tempering temperature above the temperature will extremely lost its hardness. So the spring steel is more suitable for high temperature operation.
B ) spring steel has good elasticity, it is easy to install, the inner ring can by means of the two hook spanner installed in any position, the internal tension of inner ring to make the fastening on the shaft. Elastic material and machining tolerances for H9 or h1l of the inner ring is relatively easy to implement.
C ) had little effect on the bearing durability and dirt, iron, water and falling powder with water to form weak. Left a larger space thin-walled spiral ring rolling components of large diameter. These components can scroll through the spiral gap stolen goods and foreign matter to a spiral ring. This can keep the surface clean in the rotation bearing.
The main advantages of D ) spiral bearing outer ring can be used repeatedly, which makes once due to the effect of temperature and produce can be reprocessed as possible on the damage and bending. In this case, the bearing seat also need to be adjusted. The structure design and not the complete bearing spiral ring is only needed to be changed, all the rest of bearing partscan be used again. Adjustment of bearing seat through the diameter to 1 mm increased the amplitude of the way of the. For example: when the diameter is increased from 105mm to 106mm, the spiral outer diameter also need to increase the LMM to install. This situation can be repeated to a diameter of up to 110mm. This bearing outer ring can be repeated 5 times. This can save a lot of cost, especially can be used repeatedly for 6 times in the case of all other bearing components.spiral roller bearing rolling system introduced spiral roller bearing steel winding. Therefore, called spiral roller bearing. This kind of bearing has greater elasticity and radial clearance, can bear greater impact can not bear radial load, axial load, low speed limit. Applies only to the rotation accuracy is not high, and often have a larger impact load component. Bearing installation allows the inner ring and outer ring axis axis with 0.5 °tilt. Because of this kind of bearing elastic deformation, can not guarantee the accuracy in the work, so the spiral roller bearing accuracy only ordinary grade A, no other precision level.
spiral roller bearing inner ring of the bearing outer ring features, by alloy steel strip coiling, special processing and assembly. Spiral slot bearing inner and outer ring surface, can make the lubricating oil continuously and uniformly throughout the working surface of the bearing. Bearing working in a larger temperature difference condition, bearing fit size can be automatically compensated.
spiral roller bearings use spiral roller bearing is usually used in the major steel mills
