Yangquan slewing bearing 134.45.2240.002 installation

Yangquan slewing ring bearing 3...installation/ ' (3,3,3) - Postcode If there are several postcodes in the bearing code, these postcodes are grouped in the following order:
/ ' (3,3,3) - internal design,
/ ' (3,3,3) - external design,
/ ' (3,3,3) - cage,
/ ' (3,3,3) - Other features.
/ ' (3,3,3) - Leave half a Chinese character space between the postcode and the basic code in the group
/ ' (3,3,3) - Dustproof in the group The exception is the suffix code of the cover and sealing ring. A hyphen is placed in front of the suffix code
/ ' (3,3,3) - The suffix code in the group is preceded by a slash. Slashes are also used to separate two
/ ' (3,3,3) -group suffixes in the following two cases. The first suffix ends with a digit and the second suffix ends with When numbers begin. Example:/3/. B. When the suffix code indicating the compression and/or movement clearance range is followed by a suffix code indicating the grease type, omitting the slash will cause confusion. For example -/(+).
/ ' (3,3,3) - Internal design, B,,, when the normal internal structure changes, these suffix codes and their combinations generally form part of the bearing series codes, and they are usually only used during the transition Use it during the transition period and ignore it after the transition period. However, when they represent an alternative structure, these suffixes become permanent. Usually their meaning is specific to a certain bearing type or bearing series. For example, the contact angle of a single row angular contact ball bearing is degrees. B contact angle in degrees. The contact angle is in degrees. The contact angle is in degrees. B-type bearings with a contact angle of 10 degrees, the steel ball is enlarged, and the cage is made of glass fiber reinforced nylon. The standard design of double row angular contact ball bearings with an outer diameter of less than or equal to 1 mm has no ball installation gap and uses glass fiber reinforced nylon cage. There is a ball mounting port on one side of the bearing, which can accommodate more steel balls, so it has higher radial and axial load-bearing capacity. Spherical roller bearings, these are designed for large sizes and have symmetrical rollers. There are fixed retaining edges on both sides of the inner ring, and the moving retaining ring is guided by the inner ring. The cage is a solid brass or steel frame. The optimized bearing roller and raceway surfaces help guide the rollers and reduce friction. Type with reinforced rollers to increase load capacity. ,, The rollers of this type of bearing are symmetrical and the inner ring has no ribs. Each row of rollers has a stamped steel plate cage. The moving retaining ring is guided by the inner ring. Type bearings use reinforced rollers to increase load capacity. The roller and raceway surfaces of these bearings are optimized to help guide the rollers and reduce friction. The company adopts the latest standard design, the bearing rollers are symmetrical, the inner ring has no ribs, the movable middle retaining ring made of iron bronze is closest to the outer ring, and is guided by a cage. Each row of rollers has a stamped steel plate cage. Type bearings have all the advantages of type bearings. The latest development of the cage can accommodate more extended rollers with larger diameters, making the bearings have a higher load capacity. The outer ring of the bearing has an oil groove and three oil holes, so the rear code must be added to show the difference. Cylindrical roller bearings B bearings use surface-treated rollers (full complement roller bearings). B Bearing ring surface and roller surface are treated (full complement roller bearing). The internal geometry of the bearing has been improved to have a higher load-bearing capacity. The ribs and roller end faces have good contact and lubrication conditions and can withstand higher axial loads.
