High-Ratio,
Hypoid Gears (MHP)
High speed reduction ratio, high efficiency, high rigidity and compact gear assembly.
Ground Spiral Bevel Gears
(MBSG)
High strength, abrasion-resistant and compact for high-speed & torque use.
[NOTE1] Even though the bore and the hub portions are masked during the carburization and they can be modified, care should be exercised since the hardness is somewhat higher.
Ground Spiral Bevel Gears
(SBSG)
Reasonably priced ground gear, yet remachinable except for the gear teeth.
Spiral Bevel Gears
(MBSA·MBSB)
Ready to use without performing secondary operations. Strong and abrasion resistant.
[NOTE] The letters “B” at the end of catalog numbers designate same items except for changes in the bore and keyway sizes.
[NOTE1] MBSA(B) spiral bevel gears are carburized and do not allow secondary operations. However, the back surface of B7 style gears is masked during the process so that it is possible to drill and pin on this surface.
Spiral Bevel Gears
(SBS)
Large nos. of teeth and modules are offered in these affordable spiral bevel gears.
Ground Zerol Bevel Gears
(SBZG)
[Translation necessary:en]ねじれ角が10°以下のまがりばかさ歯車です。歯車に働く力の向きがすぐばかさ歯車と同じで高精度な製品です。
