What is the difference between UCF bearings and UCFU bearings?
There are no differences between the two bearing codes, all of which are square, top and outer spherical bearings.By current standards, it should be UCFU. Square block old code name is F, the new code name is FU, but because the code is combination, often in the FU U omitted, so this omission U name is widely called.UCF bearings are generally used in: insulating glass production lines, engineering and engineering design,Inkjet printer, condiment processing equipment, heat exchanger, sewage treatment equipment, pump, electric welding machine, sewing machine, worktable, sieve, electroplating equipment, polishing machine, rubber molding machine, pelletizing machine,Plastic calender, agricultural machinery fittings, granulating drying equipment and so on.
Still have a lot of different dimensions, are basically the same, but the inner ring of the bearing's position is not the same ~ can see bearing sample KFC, many parameters are not the same, such as S, if there is a shoulder against the inner word axis, we must distinguish,.
According to the definition of standard JB/T 6640-2007 "rolling bearing spherical ball bearing code method", UC is a type of structure bearing code, with the top wire outer spherical ball bearing; FC is the type code of the bearing seat, said casting raised circular seat; UCFC is ball bearing structure type code, said with the convex platform round a top silk outside spherical ball bearing type structure.The definition of UCF code in the above standards, the domestic and outer bearing seat type control, UCF, NTN or NSK product code, corresponding to our code named UCFU, the standard is defined with square seat top silk outside spherical ball bearing type structure.The current standard should be UCFU...... This square block old code name is F, the new code name is FU, but because the code is a combination of FU in the U province will not cause ambiguity, so this omission U name is widely called. In fact, these two terms refer to one thing.
