Frequently Asked Questions (FAQ):
1. What is the maximum input speed for the MBY500 gearbox?
The recommended input speed is typically 1000-1500 RPM. For higher speeds, please consult our engineering team.
2. Can the gear ratio be customized outside the 5.6-8.0 range?
Yes, we offer custom ratios upon request, but the standard model covers this range. Additional design fees may apply.
3. Does the gearbox come with a cooling system?
Standard models come with natural cooling. For high-temperature environments, forced lubrication with cooling fins or an external oil cooler is available as an option.
4. What type of lubricant should be used?
We recommend ISO VG 320 or 460 mineral-based gear oil. Synthetic oils can also be used. Full lubrication guidelines are provided in the manual.
5. How is the spline output shaft dimensioned?
The spline dimensions follow DIN 5480 or ISO 14 standards. Custom splines based on customer drawings are accepted.
6. What is the typical lead time for this gearbox?
Standard models have a lead time of 30-45 days. Customized orders may take 45-60 days, depending on complexity.
7. Do you offer spare parts packages?
Yes, we provide a recommended spare parts list (seals, bearings, gaskets) for two years of operation. Spare parts can be shipped together or separately.
8. Can the gearbox be used for other applications besides ball mills?
While optimized for ball mills, the MBY500 can be adapted for kilns, conveyors, and crushers after verifying torque and speed requirements. Contact us for a feasibility check.
