If the mating member material is cast iron or aluminum, reduce the tightening torque depending on the strength characteristics of the mating member material. Please do not tighten with too much torque as abnor-mal frictional torque or short life may occur.Table 17 Tightening torque of mounting boltsBolt sizeM2.5×0.45M3×0.5M4×0.7M5×0.8M8×1.25TighteningtorqueN・m0.581.74.07.9Bearings is indicated in Table 17. When machines or Dd 32 Structure of Double-acting Angular Roller BearingAbove values are for Carbon steel bolt (Strength division 12.9)■Double Row Angular Contact Roller BearingWe manufacture Double Row Angular Contact Roller Bearings to order. If needed, please contact IKO. Double Row Angular Contact Roller Bearings have a large number of cylindrical rollers with a large contact area with a raceway and an excellent load capability, between the inner and outer rings arranged in a dou-ble row of raceways. This underpins even higher rigidi-ty and lower torque than High Rigidity Type Crossed Roller Bearings V. The mounting holes in both inner and outer rings facil-itate installation to your machines and equipment. Further, the integrated structure (non split) construct-ed in both inner and outer rings can avoid installation errors, yielding extra-high-rigidity and high-accuracy guiding performance without being affected by other Outer ringperipheral structures such as housing or pressure plate.For lubrication, use the two oil holes on the outer ring outer surface shown in Fig. 6.Iject reaseInjct greaseCylindrical rollerSeparatorInner ringGreaseGreaseGreaseInjctgrease 1Inject grease Fig. 6 GreaseJ14
