Structure of LYHY slewing bearingsMain Types:Single row ball slewing ring bearingsDouble row ball slewing ring bearingsCrossed roller slewing ring bearingThree row cylindrical roller slewing bearingsBALL & ROLLER combinedslewing bearingsFlanged slewing ring bearingGear Type:Slewing bearings with external gearSlewing bearings with internal gearSlew bearings without gearFlange type:Slewing bearings with external flange and internal gearSlew rings with internal flange and external gearSlew bearings with external and internal flange3. Double-row ball slewing ring bearingsCharacteristic of structure, performance and application:Our factory is a specialized manufacturer in slewing rings/bearings.The double-row ball slewing ring bearing has three seat-rings. The steel balls and the spacers may be directly arranged into the upper and lower races. Two rows of steel balls with different diameters are fitted according to the force.Such open mode fitting features extraordinary convenience. The load angels of both upper and lower races are 90° which enable the bearing to bear large axial force and the tipping moment. When the radial force is larger than 1/10 of the axial force the races should be newly designed. As the axle and the dimension of the double-row ball slewing bearing are rather large, the bearing construction is solidity; hence it is especially suitable for tower cranes which require working radius over medium range, mobile cranes and loading and unloading machines.4. about LYHY bearings Advantages:4.1 introduction:we are amanufacturer of slewing bearing since 1993, our factory occupies aarea of 30000square meterswith 4workshop and 1office building.4.2 Featured products:slewing bearing and slewing drive4.3 Capital:Current is 1million RMB, but we are increasing the capital to 10 million RMB4.4 Workers:604.5 Certificate:ISO9001:2008, 3.1 certificate, CCS certificateAll LYHY slew rings can betested by the 3rd party inspection organization if customer requires, such as BV, CCS, SGS, LR, ABS and so on. All swing bearings inspection reports will be supplied to customers, including raw material certificate, heat treatment certificate, UT&PT and so on.4.6 Annual Exportation:8 million USD4.7 Warranty Period:All LYHY slewing ring bearings have a warranty period of 18 months, for some special working condition, warranty period can be lengthened to 3-4 years.4.8 Production Time:All LYHY slewing ring bearings can be usually delivered timely, usual production time is 15-50 days based on different slew bearings diameters, sometimes slew rings will be in stock.4.9 Technical ControlAll LYHY slewing ring bearings are forged rings with material steel 50Mn or 42CrMo, slewing rings are machined by CNC lathe, slew bearings raceway are quenched via medium-frequency hardening with hardness 55-60HRC, turntable bearings are drilled holes by CNC drilling machine, slew gears are machined by hobbing machine with gear quenched if required, swing bearings then are grinded by grinding machine with higher precision.5. LYHY Slewing Bearing Packing5.1 Basic PackingBearing surface is covered with the anti-rust oil first; and then wrapped with the plastic film;And then packed with kraft paper and professional belts;At last, with wooden box totally at the outer packing to invoid the rust or the moist;We can depend on the customers demand to be packed;5.2 LYHY slewing ring bearings can be packed by different ways.If bearing diameter is less than 2300mm, slewing rings will be usually packed by square plywood case.If bearing diameter is more than 2300mm, slewing rings can be packed by square plywood case, round plywood case, or steel tripod.Every package way can be totally kept goods safely.6. LYHY Slewing Bearing Transportation:Slewing bearings can be offered different delivery terms, such as EXW, FOB, CIF, DDU and so on.Also, slewing rings can be transported by different transport ways, by express (such as DHL, TNT, UPS, FEDEX and so on), by air, by sea, by truck, by railway and so on.6.
