Grease Replacement of Grease-Lubricated and Maintenance-Free Models
・
The unit may be used for a long time safely, because long-lifetime grease is sealed in. However, overhaul every 20,000 hours or
3-5 years of operation ensures even longer lifetime.
・
Always consult our specialized factory for overhaul of gearmotors and reducers. Experience is necessary for overhaul.
