R27/RF27/RS27/RFS27series helical gear reducer has the characteristics of strong versatility, good combination and strong carrying capacity. It has the advantages of easy transmission ratio, high efficiency, small vibration and large radial load of shaft. This series not only can be combined with various reducers and transmissions to meet the requirements, but also facilitates the localization of related transmission equipment.
High modular design.
The integral casting shell has compact size, high load carrying capacity, stable transmission and low noise.
Good anti-leakage performance, good sealing, can be widely used in industrial production.
Cost savings and low maintenance costs.
