[Daily Bearing Network] Autumn has arrived; another year of busy farming season; agricultural machinery has begun to play an important role; the number of bearings used on some agricultural machinery is also increasing; for your agricultural machinery to operate efficiently; Some methods and precautions in the selection of agricultural machinery bearings.
Skf bearing is a support member for various mechanical rotating shafts or movable parts; widely used in agricultural machinery, tractors, diesel engines, electric motors, threshing and other agricultural machinery. The bearing code is commonly used for bearing selection; but the bearing code is more complicated; if it is a farmer Grasp the rules for identifying the bearing code; the purchase is simple.
Commonly used skf imported bearings are some standard types; code name is "0"; public service level is "g" (normal level); usually the first paragraph of the bearing can not write; therefore its code number is indicated by the 7 digits of the fundamental code The example now clarifies the meaning of the bearing code: Example 7002136 (135 series diesel engine shaft main bearing); its root code is identified from right to left. The "36" two-digit number indicates internal light; its calculation method is 36 × 5 = 180 mm "1" indicates that the diameter series is extremely light; "2" indicates that the type is cylindrical roller bearing; "00" indicates that the bearing layout mode has no ribs on the outer ring; "7" indicates that the width series is narrow. If the operator chooses 7 positions Several other types of bearing code can be analogized.
Buy skf bearing agricultural machinery bearing more refer to skf bearing inner diameter; bearing inner diameter in the top of the code name with the right end of the top, the second digit indicates that the bearing inner diameter is divided into specifications and non-standard inner diameter; the difference non-standard inner diameter is not an integer or an integral multiple of 5. To facilitate the purchase of the machine;
1, skf bearing inner diameter below 9 mm with the right end of the list of the first digit practice scale. For example, bearing number 18; its inner diameter is 8 mm.
2, skf imported bearing inner diameter at 10 17 mm with a fixed number. For example, bearing number 100, 201, 302, 403; its internal diameter code is the right end two digits are 00, 01, 02, 03; its inner diameter is 10, 12 respectively , 15, 17 mm fixed number indicates.
3, skf bearing inner diameter is 20 480 mm (22, 28, 32 outside); the number of the inner diameter scale divided by 5 indicates.
4, skf bearing inner diameter is more than 500 mm (22, 28, 32) with a fraction; the denominator indicates the inner diameter; the molecule indicates the scale series, type and layout of the bearing. For example, bearing 30031/560; its inner diameter is 560 mm; And so on.
