Series
The M series represents TwinSpin® high precision reduction gears of mini sizes. The M series is filled with grease for lifetime. The sealing of the M series reduction gears is secured by sealed (2RS) ball bearings, which are used as output bearings of the reduction gear, and also as the housing of the input shaft of the reduction gear (slight leakage of lubricant is allowed). Upon customer's request, SPINEA® is able to supply a completely sealed reduction gear. This design of the reduction gears allows the load to be mounted directly on the output flange or the case without the need for additional bearings.
Advantages
- small dimensions and compact design
- fully sealed by 2RS ball bearings
- simple installation
- zero-backlash reduction gear
- very low mass
- very high power density
- output deep groove ball output bearing with very low friction
- high performance of the reduction gear
- high precision
- high torsion rigidity
- high linearity of torsion chracteristics
- very low friction and high efficiency
