FAQs about Maintenance
What type of lubricant should be used?
Use high-quality lubricants such as synthetic oil or grease with the recommended NLGI grades for maximum performance and longevity.
What lubricants can be used for screw jacks?
Lubricating grease of NLGI grade 1 or 2, suitable for heavily loaded sliding and rolling bearings. Compatibility with the existing lubricant must be ensured. It's crucial whether the grease is mineral or synthetic-based.
What is a block drive?
A block drive describes the execution of the lift against a fixed stop. In this process, the lifting element is 'blocked' by the fixed counterpart.
How can a block drive be avoided?
The driving element, usually a three-phase motor, doesn't stop automatically but needs a signal for shutdown. This signal can be generated through limit switches, encoders, potentiometers, or other displacement-monitoring components.
Can lifting elements withstand a block drive?
Mechanical drives are very sensitive to movement against fixed stops. Depending on the force of the motor, a block drive typically results in damage to the spindle-nut system.
What faults can indicate insufficient lubrication?
Overheating, unusual noises, or a noticeable decrease in performance can be signs of insufficient lubrication. Pay attention to these symptoms for timely maintenance.
How often should the lubrication of screw jack gearboxes be performed?
Lubrication should be performed every 3 to 6 months, or after 500 double strokes, depending on the frequency of use and the environment.
Are there any specific requirements for the ambient temperature?
Increasing the ambient temperature does affect the duty cycle. A higher ambient temperature necessitates a longer cool-down period.
How do I recognize signs of wear and tear on the drive components?
Inspect moving parts for signs of wear and increasing play. If wear is detected, consideration should be given to inspection or replacement.
Can maintenance be performed independently?
Yes, the maintenance and operating manual provides valuable guidance on the procedure. You can find the documentation here.
How can I troubleshoot operational malfunctions?
Is the motor correctly wired and the brake releasing? Do you have sufficient lubricant on the spindle? Are the drives installed without tension? If so, you've already eliminated the most common sources of malfunction. If the issue persists, please call us at +49 7261/9263-0.
What role does the environment play in maintenance?
The environment can affect maintenance intervals. High levels of dust or humidity may require shorter maintenance intervals. Regularly check the environmental conditions and adjust the maintenance schedules accordingly.
My electric cylinder is not moving. What could be the issue?
Check the power supply, brake wiring, and the condition of the control unit. If necessary, contact our customer support. Also, ensure proper wiring of the limit switch. Most blockages occur during setup operations.
The linear chain is making strange noises. What should I do?
Check for dirt or worn-out parts. Thorough cleaning and, if necessary, replacement of damaged components may solve the problem. If the linear chain is noisy after acquisition, system tensions could be responsible.
My screw jack isn't responding to control signals. What could be wrong?
Check the connection to the control system and the programming. Ensure all safety precautions are accounted for.
The MINI is moving irregularly. How can I fix this?
Check the power supply. For 24V DC drives, fluctuating loads can also cause varying speeds. Additionally, ensure that potentiometers, encoders, and brakes are correctly controlled.
How can I maximize the lifespan of my high-performance screw jack?
Regular maintenance, including lubrication and checking for wear, helps extend the lifespan of your high-performance screw jack.
Is special training required for maintenance?
A thorough familiarization with the operating manual is advisable. However, in case of uncertainty or complex maintenance tasks, specialized personnel should be consulted. You can reach us anytime at +49 7261/9263-0.
Which lubricants are compatible with our products?
For compatibility, it's simply a matter of checking the base of the lubricant (mineral or synthetic) and ensuring the NLGI grade is the same. Divinol Lithogrease 1500 is commonly used as the standard.
Is it necessary for me to use the grease specified by GROB?
No, the standard grease can be replaced by other greases with the same properties. If you would like to know whether your grease is compatible with our standard grease, you can send us the data sheet of your preferred grease, and we will check it for you.

How is the lubrication of screw drives performed?
Screw drives require regular lubrication to minimize wear. The type of lubricant and the intervals depend on the operating conditions.
How is the maintenance of high-speed actuators performed?
Maintenance involves regular lubrication according to manufacturer specifications. Inspections for wear and timely re-lubrication are crucial for longevity.
