Spherical roller bearings are between the inner ring with two raceways and the outer ring with spherical races; the bearings are equipped with drum rollers. The middle of the curvature of the raceway surface of the outer ring is common with the bearing; therefore, Active self-aligning ball bearing the same self-aligning function. When the shaft and outer casing are deflected; can be actively adjusted; no shaft is required to bear negative. Spherical roller bearing can accept radial load and axial load in two directions. Radial The load can be large; it is suitable for heavy load and impact load. The inner ring inner diameter is the bearing of the tapered hole; it can be directly installed. Or use the tightening sleeve, open the cylinder device on the cylindrical shaft. , polyamide forming support frame and copper alloy car support frame.
Spherical roller bearings can accept large radial loads; they can also accept a certain axial load. The outer ring raceways of this type of bearings are spherical in shape; therefore, they have a aligning function; when the shaft is subjected to bending or skewing, The middle line of the inner ring and the middle line of the outer ring are not inclined more than 1Â°~2. 5Â°; the bearing can still work.
Spherical roller bearings are suitable for receiving heavy loads and impact loads; widely used in metallurgy, rolling mills, mining, petroleum, paper, cement, sugar and other professional spherical roller bearings in the inner ring and raceway with two raceways Between the outer rings of the spherical surface; the bearing with the drum-shaped roller. The middle of the curvature of the outer ring raceway surface is common with the bearing; therefore, it has the same self-aligning function as the active self-aligning ball bearing. Time; can actively adjust; do not add shaft to bear negative. Spherical roller bearings can accept radial load and axial load in two directions. Radial load can be large; suitable for heavy load, impact load conditions. Inner ring inner diameter It is a bearing with a tapered hole; it can be directly installed. Or use a tightening sleeve, and disassemble the cylinder device on the cylindrical shaft. The frame is adhered to the steel plate stamping frame, the polyamide forming frame and the copper alloy car frame.
Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3~10 times the diameter; the diameter is usually not more than 5mm); therefore, the radial layout is compact; the inner diameter scale and load can be combined with other types of bearings; The most defensive ä¹‡é¹— ç³œåˆ– è™¬æ²§ä¿ºå½ç¼¡èŠŸæ‹— è™¬æ²§ä¿ºå½ç¼¡èŠŸæ‹— Ð¡ Ð¡ Ð¡ Ð¡ ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ä¾æ® ; ; ; ; ; ; ; ; ; ; ; The exterior and outer casing holes are directly visible inside the bearing. Outer roll appearance; the ability to adhere to the load and work function is the same as the ferrule bearing; the hardness of the shaft or shell hole raceway appearance. Machining accuracy and appearance and appearance quality should be similar to those of bearing rings. Such bearings can only accept radial loads.
