To fall immediately, and there is the busy season a year, some began to farm machinery displayed their prowess on the. With fall approaching, some of the bearings used in amount of use of agricultural machinery increased. In order to facilitate agricultural hand purchase of agricultural machinery bearings, DU bushing shaft Research Co., Ltd. Shanghai engineer to you on skf bearings Agricultural bearings purchase method.
skf bearing a variety of mechanical or moving parts of the axis of rotation of the supporting parts are widely used in agricultural vehicles, tractors, diesel engines, motors, threshers and other agricultural machinery. Bearing bearing code used to buy, but bearing code more complicated, and if the farm hand to grasp the law of identification bearing code, buy it easy.
Skf bearings are commonly Mould guide plate used some of the standard model, code-named "0" tolerance level for the "g" (general level), the general bearing of the first paragraph can not write,plasic bushing so the code more to the basic code of the 7 digit number. To illustrate the meaning of the bearing code: case 7002136 (135 series diesel engine shaft main bearing),plain bearing the basic code from right to left to identify. "36" digit of light, which is calculated as 36 × 5 = 180 mm; "1" in diameter series special light; "2" indicates the type of cylindrical roller bearings; "00" indicates the bearing outer structure without ribs; "7" series, said narrow width. If the machine hand to buy 7-digit code to other standard models bearing and so on.
Buy skf bearings Agricultural bearings skf bearing multiple reference diameter, bearing ID code used in the basic right first and second digit represents. Sub-standard and non-standard bearing bore diameter, the difference between non-standard ID is not an integer or integer multiples of 5. To facilitate brass bushing machine hand to buy, are an example:
1, skf bearing diameter of 9 mm below the actual size with the right end of the first digit, said. For example, bearing number 18, the inner diameter of 8 mm.
2, skf bearings 10-17 mm in diameter with a fixed number, said. For example, bearing No. 100,201,302,403, and its diameter were right two-digit code is 00,01,02,03, 10,12,15,17 mm internal diameter were fixed digits.
3, skf bearing 20-480 mm in diameter (except 22,28,32), in addition to diameter size from number 5 said.
4, skf bearing diameter 500 mm (22,28,32) with a fraction, the denominator of that diameter, the size of the bearing elements, said series, type and structure. For example, bearing No. 30031/560, its diameter is 560 mm, the other and so on.
