One-way bearing is a kind of nsk imported bearing that can be freely changed in one direction; and locked in the other direction. The metal casing of the one-way bearing; includes many rollers; needle roller or ball; and its rolling seat The shape of (hole) makes it only roll in one direction; in the other direction, a large resistance (so-called "one-way") solid one-way bearing uses GCr15 bearing steel; the hardness after heat treatment is HRC61-65; The bearing is small in size and has high bearing capacity; there is a space for storing smooth grease; it can have a longer smooth distance.
The powder metallurgy one-way bearing and the solid one-way bearing can completely “lock” the drive shaft when it is driven by the driving force; it avoids the problem of the lack of the “locking” function of the traditional one-way bearing of the drawn outer ring.
The product specification SH 0017 90 "Bearing Oil" formulated in accordance with the classification of GB 7631.4 89 was implemented on April 1, 1992; instead of SYl229 82 (88) "Spindle Oil". Japan nsk bearing new specification l FC points 2 100 11 viscosity numbers; L FD 2 22, etc. 7 viscosity number one-way bearing main use: textile machinery, printing machinery, automotive industry, household appliances, money detectors.
The specific classification of Group F (spindle, bearing and clutch) is determined by GB 7631.4 89; it is divided into 2 categories.
FC is refined mineral oil and participates in additives to improve its corrosion resistance and oxidation resistance. Suitable for sliding or rolling bearings and related clutch pressure, oil bath and oil mist (suspended particles) smooth FD is improved on the basis of FC anti-wear Sexual. Suitable for sliding or rolling bearings. Pressure, oil bath and oil mist (suspended particles) are smooth to avoid corrosion or slippage of the clutch. FC oil should be free of anti-wear or extreme pressure additives.
One-way bearing powder metallurgy one-way bearing selects the molding and sintering process to make metal powder (or a mixture of metal powder and non-metal powder) into the product. Based on the characteristics of the powder and the process modification characteristics; Japan nsk imports The bearings use the corresponding skill process; changing the shape, function and arrangement of the powders becomes a bearing product that is used to different needs.
