Other Products
MMSG
(MMSG)
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.
SMSG
(SMSG)
Reasonably priced ground gear, yet remachinable except for the gear teeth.
MMSA・MMSB
(MMSA·MMSB)
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] MMSA(B) spiral miter gears are carburized throughout so that they do not permit any 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.
MMS
(MMS)
Only teeth are induction hardened, allowing user to perform secondary operations elsewhere.
[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.
SMS
(SMS)
Large numbers of teeth and modules are offered in these affordable spiral miter gears.
SMZG
(SMZG)
[Translation necessary:en]ねじれ角が10°以下のスパイラルマイタです。歯車に働く力の向きがストレートマイタと同じで高精度な製品です。
SMA·SMB·SMC
(SMA·SMB·SMC)
Usable without remachining, offered in 3 bore sizes.
[NOTE] The letters “B” and “C” at the end of catalog numbers designate same items except for changes in the bore and keyway sizes.
Carburized & Hardened
Miter Gears (MM)
Compared to SM miters, these are stronger and less abrasive, and allow secondary operations.
[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.
LM
(LM)
Mass-produced, low cost sintered products. Small and light weight.
[NOTE] Sintered metal Miter Gears are manufactured by mixing powdered metal and pressing them in a mold under heat to fuse, sizing and impregnating with oil.
SM
(SM)
Popular straight miter for many uses.
SAM
(SAM)
3 types are available for shafts at 45°, 60° and 120°.
Stainless Steel
Miter Gears (SUM)
Suitable for food machinery due to SUS303’s rust-resistant quality.
Finished Bore
Stainless Miter Gears (SUMA)
Suitable for food machinery due to SUS303’s rust-resistant quality.
PM
(PM)
MC nylon products are light and can be used without lubricant.
Injection Molded
Miter Gears (DM)
Injection molded, mass-produced products, suitable for office machines.
Nissei KSP
Ground Spiral Miter Gears
Superior performance with regard to high speed, low noise, and low vibration.
