Frequently Asked Questions
Q1: What is the typical lifespan of this gear unit?
A: Under normal operating conditions with proper lubrication, the gear unit can operate for over 20,000 hours. The use of high-quality bearings and hardened gears further extends life.
Q2: Can this gear unit be used in washdown environments?
A: The standard version is not sealed for washdown, but we offer optional IP65 protection with additional seals and coatings. Please inquire for customization.
Q3: What type of oil should I use?
A: We recommend ISO VG 220 synthetic gear oil for optimal performance. The unit is shipped without oil, so you must fill it to the indicated level before operation.
Q4: Is the output shaft reversible?
A: Yes, the gear unit can operate in both clockwise and counterclockwise directions. The input rotation direction determines the output rotation.
Q5: What mounting position is allowed?
A: The unit can be mounted in horizontal, vertical, or inclined positions. However, for vertical shaft-down applications, an oil level adjustment may be needed. We provide a mounting position guide upon request.
Q6: Do you offer custom reduction ratios?
A: Yes, we can manufacture gear units with reduction ratios from 5:1 to 100:1. Contact our sales team with your specific requirements.
Q7: What is the warranty period?
A: We provide a standard 12-month warranty from the date of shipment against manufacturing defects. Extended warranty options are available upon request.
Q8: How do I select the right motor coupling?
A: The input shaft of this gear unit is designed to accept a standard IEC motor flange. We recommend using a flexible jaw coupling to accommodate minor misalignment. We can supply the coupling as an accessory.
