Benefits and Features KOYO bearings
Most favorable price : sales@hellerbearings.com
1 abrasion - because the ceramic material is an inert material , it is more resistant to corrosion and wear ;
2 , long life wear - fatigue life of full ceramic bearings KOYO Bearing KOYO longer than expected 10-50 times , hybrid ceramic bearings KOYO , high life expectancy than KOYO bearing life is about 3-5 times ;
3 , high speed and acceleration - can operate at more than 3 million dn value conditions and slippery , wear and heat can be reduced ;
4 , high temperature - Full ceramic bearings can KOYO 500 . C above the temperature of the work ;
5 , rigidity - by the elastic modulus of the ceramic material is high, its rigidity than ordinary steel KOYO BEARINGS 15-20 % ;
6 , the required minimal lubrication - low friction coefficient of the ceramic material , the use of oil- lubricated bearings KOYO ceramic , in the case of thinning or lean oil , the lubricating ability is still lower than the commonly used conventional steel bearings lubricated KOYO agent ;
7 , low torque - the structure of the ceramic bearing KOYO torque decreases by about 1 / 3 ;
II: quenched and tempered steel Features:
1 in hardenability steel:
Oil quenched steel directly in class 40 ~ 60n, m, commonly used steel chrome -molybdenum steel , chromium, manganese , etc. Common grades for 35 (jrMn, 42CrMo, 35L: rMnV, 40CrMn, 35CrMnSi, 30CrMnsi, 35 (: rMnTi, 40crMnTi, 40crNi etc. , chromium molybdenum steel with high hardenability , high temperature strength and good organizational stability, eliminate back fire brittle characteristics , 42CrMo used to manufacture high strength requirements , the quenching cross section of large parts , such as gears , turbine shaft , the connecting rod by a large load , but also can be made ??in 5 (:) o ℃ or less long working parts ; higher chromium -manganese steel hardenability and strength, toughness, not reduce , 30 (: rMnsi high- strength steel, has good weldability , for the manufacture of high pressure blower compression chip , high-speed wheel axle load and other important parts.
(2) high hardenability steel:
Oil cold steel in critical diameter class 60 ~ 1 OO mm. Common material grades are 30Mn2MoW, 40CrMnMo, 30 (: rNi3, 37CrNi3, 40CrNiMc), 45CrNiMov, 25cr2Ni4w etc. , 40crMnMo is commonly used high hardenability of steel , with a small temper brittleness , overheating tendencies and other characteristics , used to make cut area, high strength and high toughness parts, such as a large heavy-duty vehicle axle and so on .
3 low hardenability steel:
Small cross-section and is generally used to manufacture parts unimportant ; chrome steel has good hardenability , tempering steel having a stability higher than the quenching temperature in width , not overheating, distortion cracking tendency is small, the wide range of applications ; similar to the role of manganese chrome steel , manganese steel, the critical cooling rate is greatly reduced , improving the strength and hardness of steel ; boron- boron steels significantly improves the hardenability of steel , its performance is close to 40Cr, oil quenched critical diameter in the 20 ~ 30mm, commonly used for automobile axle , worm , spline shaft.
