Precision Stainless Ball Bearings Precision Stainless Ball Bearings, We delivers the corrosion resistance and superior hardness of stainless steel in a wide variety of bearing types, ideal for applications in food/beverage, medical and other environments where moisture, corrosive or abrasive materials are present. AISI 440C 1% C, 17% Cr, . 5% Mo A hardened, martensitic stainless steel, 440C is the standard choice for a wide range of military and commercial applications.
Bearing in the manufacture of complete and qualified by examination, or cleaning and rust prevention treatment, then put inside the package to achieve the water, moisture, dust, shock, maintaining the quality and precision bearings, and ease of use and sale purposes. Packaging materials bearing a polyethylene plastic tube (box), kraft paper, plain and wrinkles polyethylene paper, cartons, polyethylene or polyethylene plastic film, the preparation of nylon or plastic fastened with fastening tape,
A, to improve the quality of bearing maintenance and assembly, and strictly control the passing rate on the bus link. Raise the bearing hinges with the quality of the bearing on the back is smooth, without spots, positioning bump intact; own bounce volume 0.5 ~ 1.5mm, which can ensure that after the bush with self-assembled bearing hole stretch and fit tightly; on the new the old link be asked to measure the degree of parallelism and twist on the unqualified prohibition on the train connecting rod;
Spiral bearing three characteristics:1. The main advantage of spiral bearing outer ring can be reused many times, making the event as due to the damage caused by the impact of temperature and bending to its re-processing possible. In this case, bearing also need to be adjusted. Structural design of such structures, not only spiral package bearing the outer ring needs to be change, all the other bearing components can be used again.
Today, demands the right to use life, equivalent load, shaft speed and improve the reliability of any correction factor can be used to calculate with the required load bearing capacity. Where: C = dynamic load rating required capacity, N = Shaft speed, r / min Rolling contact type θ = dimensionless index L = L required service life, h P = bearing equivalent load, N Point contact (ball bearings) or line contact (roller bearings). On ball bearings: θ = 3. 00,
1: bearing steel ball production process:1, grinding: the ball into the rough match with the rough size, upper and lower multi-channel measurements with the same concentric ring section slot grinding mill for the triangle, add oil, crude abrasives; on the disc rotation, the next disc Fixed. Ball machine, said more than rough mill. Necessary, coarse grinding can have Road.2, system of embryos: use of a variety of processes to produce a variety of spherical rough way.
1: How to improve the bearing accuracy:1, the precision spindle bearings and can not meet the requirements, after the bold and the fabrication journal roller to replace the inner ring and ball were measured waxy close to a size for every three groups ball close to 120 ° intervals to take separately, due to a decrease of the surface of a re-processing, but also reduces the surface with a weight, while improving the axial stiffness of a bearing system,
1: ntn bearing raceway noise:1. To avoid the rolling force on adoption, which requires assembly and disassembly inner ring (shaft loop), through the force on the inner ring, outer ring assembly and disassembly time) by force on the outer ring.2. Drag force due to continue until the extent of, for example, when installing the bearing mounted in the bearing to the right location just stop3. Force on the size of the appropriate steady uniform should not have impact,
