Spherical plain bearing is a spherical sliding bearing whose sliding contact surface is an inner spherical surface and an outer spherical surface. It can be rotated and oscillated at any angle during movement. It is made by surface phosphating, blasting, inlaying, spraying and other processing methods.
Spherical plain bearings have the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning and good lubrication. According to different types and structures, it can bear radial load, axial load or combined radial and axial load. The application scenarios are: water conservancy and professional machinery.
Our company distributes bearings of major brands with sufficient inventory.
We professionally provide GE/GEH/PHS/POS type bearings to provide you with the best quality service! If you have any needs, we can also provide you with brand (such as NTN, FAG, SKF, etc.) alternative services to meet your needs! Welcome to consult!
1. INTRODUCTION:
（1）Different in nature
Oriented silicon steel: Oriented silicon steel, also known as cold-rolled transformer steel, is an important ferrosilicon alloy used in the transformer (iron core) manufacturing industry.
Non-oriented silicon steel: Non-oriented silicon steel is a ferrosilicon alloy with very low carbon content, and its grains are distributed in random orientation in the steel plate after deformation and annealing.
（2）Different characteristics
Oriented silicon steel: The magnetism of oriented silicon steel has strong directionality, the iron loss value is the lowest in the rolling direction, the magnetic permeability is the highest, and it has a high magnetic induction value under a certain magnetization field. The silicon content of grain-oriented silicon steel is about 3%, and the content of oxide inclusions in the steel is required to be low, and it must contain some kind of inhibitor (MnS, A1N ).
Non-oriented silicon steel: Non-oriented silicon steel is a ferrosilicon alloy containing 0.8%-4.8% silicon, which is hot-rolled and cold-rolled into a silicon steel sheet with a thickness of less than 1mm. Adding silicon can increase the resistivity and maximum permeability of iron, and reduce the coercive force, core loss (iron loss) and magnetic aging.
（3）The production process is different
Oriented silicon steel: Oriented silicon steel is smelted in an oxygen converter. The billet is rolled into finished product thickness through hot rolling, normalization, cold rolling, intermediate annealing and secondary cold rolling, then decarburization annealing and high temperature annealing, and finally coated with an insulating layer.
Non-oriented silicon steel: pre-desulfurization of molten iron, secondary desulfurization by adding Ca0+CaF: flux or rare earth elements and calcium during converter blowing. The boiling molten steel is decarburized by vacuum treatment and then further desulfurized. Ferrosilicon with low titanium and zirconium content is selected for alloying.
