Part two: rolling element diameter, represent by double digits. mttofcM&tt^: &mm%MM®R-tMfti»*}, tfc&wM&Fma 50 mi 5 ^% 10,15, Rolling element diameter symbol: To make number as per dimension of rolling element diameter. If rolling element diameter is not more than 50, take 5 as carry, divide into 10, 15, 20, 25, 30, 35, 40, 45, 50, number according to dimension nearest value. If rolling element diameter is more than 50, take 10 as carry, i.e. 50, 60, 70 increasing, number according to the rounding of actual rolling element dimension. Part three: center circle diameter of rolling element,...

Slewing bearing material Precise design and proper selection of bearing manufacturing material is the important guarantee for ensuring SBI slewing bearing with high technical performance and...

Cage material The cage forms of SBI slewing bearing include integral type cage, sectional type cage and spacing block type cage etc. Among them, integral type cage or sectional type cage adopt brass, carbon steel , cast aluminum and nylon. Spacing block type cage adopt polyamide resin, nylon, cast aluminum and aluminum bronze . Sealing ring material The sealing ring material of SBI slewing bearing adopt oil-resistant NBR to make, for higher temperature range occasions, may adopt fluorine rubber.

Slewing bearing clearance Slewing bearing clearance is mainly used to compensate manufacturing error and installation error between bearing supporting part and main machine assembling position and ensure bearing normal usage. According to structural style/tolerance grade and rolling element center circle diameter, the clearance value or pre-interference of slewing bearing are listed in table 1 to table 3. Table 1 Four point contact ball slewing bearing axial clearance urn Slewing bearing installation and maintenance Loading and unloading & storage and transportation Slewing bearing must be...

Slewing bearing installation Requirements of mounting bracket Mounting combination bracket normally adopt barrel type structure, tunnel wall must be in alignment with raceway center. In order to avoid slewing bearing partial overload, ensure operating flexible, mounting bracket should be relieved internal stress after all welding sequence, and process mounting plane, the planeness (include plane angular deviation) should be controlled within a certain range, see table 4: Table 4 planeness allowable value including angular deviation Bolt holes of mounting bracket should be processed as per...

jumping point on the gear and the gap between driver gears here needs to be adjusted. tax, mnmm<b\\x^vmmmMMiBm-m° um^mmmm&m^M, mm&m&mt* Slewing bearing has been lifted at position when mounting, use feeler gauge to inspect flatness of abutted plane. If the clearance is too large, need to re-machine, if really unable to process, may fill plastics or fill up with washers in local region, so as to avoid bearing deformation after bolt was tightened and affect slewing bearing performance. After slewing bearing radial locationing .tighten mounting bolt in star-junction mode, inspect bearing...

Small quantity of No.2 or No.3 lithium base grease should be coated into raceway when slewing bearing leaving factory, customer should refill new grease according to different working conditions in using. iM&^m&amm^, m^mimmmm, - -mmmmmmnm%-100 ^mum- -m^m ^fttt*#5o/>wip^-^, tmtfjTimm, ta^-u. mm±, u&^t^uRmmxwst, Slewing bearing should be filled grease at regular intervals during use. In general, ball slewing bearing fill oil once per 100 hours, roller slewing bearing fill oil once per 50 hours. In special working environment, such as high temperature, high humidity, dusty, great temperature...
