SKF thrust roller bearings are mainly characterized by the following aspects: axial and radial combined loads for axial loads; but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings Such SKF bearing has a lower collision factor; higher speed; and has a self-aligning function. The stick of the 29000 type bearing is an asymmetrical spherical roller; it can reduce the relative sliding of the roller and the raceway during operation; Large length, large diameter; large number of rollers; high load capacity; generally oil smooth; single low speed condition can be used for smooth grease. When drawing and selecting; should be preferred, 80,000 type thrust cylindrical roller bearing, 90000 type thrust cone rolling Sub-bearings and AXK thrust needle bearings; capable of accepting one-way axial loads; it is much larger than the axial load of thrust ball bearings; and it has high rigidity and small axial space. Thrust cylindrical roller bearings And thrust needle roller SKF bearings are suitable for low speed applications; thrust tapered roller bearings rotate slightly faster than thrust cylindrical roller SKF bearings. Detailed classification and type control:
1. Thrust cylindrical roller bearing (80000 type)
Note: It can accept large one-way axial load; restrain one-way axial displacement; low limit speed 2, thrust spherical roller SKF bearing (29000 type)
Note: For radial and axial combined loads that are mainly subjected to axial loads; radial loads must not exceed 55% of axial loads; one-way axial loads can be accepted; axial displacement of one direction of constrained shafts (shells) , thrust needle roller and cage assembly (AXK type)
Note: Suitable for low speed applications

Silicon Carbide (SiC) is used Quartz Sand, petroleum coke (or coal), wood chips as raw material through high temperature resistance furnace smelting made.Silicon carbide is also called moissanite. Silicon carbide is most widely used in the modern C, N, B, and other non oxide high technical refractory raw materials.Silicon carbide hardness is very high, Black silicon carbide containing SiC about 95%, its toughness is higher than green silicon carbide, most of the material used for processing low tensile strength of materials, such as glass, ceramics, stone, refractory, cast iron and non-ferrous metals, etc.
