How to buy agricultural machinery bearings
2017-06-02
Bearings
are a variety of mechanical rotary shaft or movable parts of the
support, widely used FB090 bronze liner in agricultural vehicles,
tractors, diesel engines, motors, threshers and other agricultural
machinery. Buy bearings commonly used bearing code, but the bearing code is more
complicated, if the farmer to master the rules of identification of
bearing, the purchase is easy.
Commonly
used bearings are some standard models, code-named "0", the tolerance
level is "G" (ordinary level), the general bearing can not write the
first paragraph, so its code multi-variable cylinder copper sets to the
basic code of the 7 The number of said. For
example, the meaning of bearing code: Example 7002136 (135 series
diesel engine shaft main bearing), the basic code from the right to the
left to identify agricultural machinery bearings. "2"
indicates the type of cylindrical roller bearings; "00" means the
bearing structure of the outer ring (2), the type of cylindrical roller
bearings, No ribs; "7" means that the width series is narrow. If the player to buy 7-digit other standard model bearing code can be such a push.
Optional
bearing multi-reference bearing diameter, bearing diameter in the basic
code with the right side of the first and second digits. Bearing
the inner diameter of the standard and non-standard internal diameter,
the difference between non-standard inner diameter is not an integer or 5
multiple. For
the convenience of hand to buy, is an example: ① bearing diameter of 9
mm below the right with the first number of actual size. Such as bearing No. 18, with an inner diameter of 8 mm. ② bearing diameter of 10-17 mm with a fixed number. For
example, bearing number 100,201,302,403, the inner diameter of the
right are two digits are 00,01,02,03, the diameter of 10,12,15,17 mm,
respectively, a fixed number. ③ bearing diameter in the 20-480 mm (except 22,28,32), in diameter to the number of 5 said. ④
bearing diameter of 500 mm or more (22,28,32) with the fraction, the
denominator that the diameter, the bearing bearing size of the series,
type and structure. For example, 30031/560 bearing, its diameter is 560 mm, the other and so on.
