2. Screw jacks (Basic version)

Screw jacks are typically delivered with long-term lubrication, usually consisting of a grease filling, though oil can be used in special cases. For moderate use, it is recommended to re-lubricate the jacks approximately every 500* double strokes.

*Please note that this value can vary significantly based on factors such as duty cycle, load, temperature, speed, and stroke length. For specific situations, we are happy to offer advice.

Re-lubrication is done through the grease nipple located on the end face of the jack.

Due to the wiping effect on the spindle, there may be minor grease leakage, which is balanced out by regular re-lubrication. If such grease leakage is undesirable, the jack should be sealed, though this will require separate lubrication of the spindle to avoid dry running.

For hard-to-reach screw jacks, it is advisable to use Perma lubrication units or connect them to a central lubrication system. In the standard version with a square tube rotation prevention, it is advisable to adhere to the aforementioned lubrication cycle depending on the duty cycle. For versions with a safety nut, it is recommended to check the control gap at least twice a year, which can also be done automatically with sensors if desired.

Since screw jacks are generally difficult or cumbersome to remove, we recommend "over-lubrication" to flush out old grease (i.e., continue adding grease until only new grease comes out). This can be done at the spindle or at the removed shaft seals. Note: For the basic "upright" version, the plug should be removed from the protective tube to drain excess grease.

2.1 Lubricants

The choice of a lubricant for screw jacks and spindles must meet the specific environmental requirements. The use of lubricants from other manufacturers is permitted, provided they comply with the technical specifications.

For maintenance, lubrication, or oil changes, lubricants from other manufacturers can also be used, provided they have similar properties. Upon request, we offer all mentioned lubricants, including those suitable for extended temperature ranges and specific requirements (e.g., in the food industry).

For example, DIVINOL LITHOGREASE 1500, a high-quality grease for rolling mills and the lubrication of spindles, is available. This grease is based on a lithium complex soap and has a temperature range of -20°C to +150°C/-4°F to +302°F (NLGI Class / DIN 51 818: 1).

For gearboxes with oil filling, we initially use DIN 51517 CLP 220 (gear oil) in ISO viscosity class DIN 51510:220. For special applications, the appropriate type of oil is specified.

3. Screw jacks (Traveling nut version)

Our screw jacks are delivered from the factory with long-term lubrication (oil lubrication in the gearbox). Depending on operating conditions, we recommend re-lubrication after approximately *500 double strokes.

*The exact frequency depends on factors such as operating duration, load, temperature, speed, and stroke length. Our experts are available for assistance with special requirements.

In addition to regular maintenance, the entire oil filling should be replaced after 1000 operating hours or every 5 years. The gearbox must be thoroughly cleaned before refilling. For traveling nut versions, we recommend greasing the spindle before installation.

Since we may not always know the specific design, we ask our customers to provide a lubrication connection on the traveling nut. In cases of hard-to-reach screw jacks, consider using Perma cartridges or connecting to a central lubrication system.

4. Linear chain

Even in well-designed electromechanical drive systems like linear chains, lubrication and maintenance are crucial for ensuring high performance and a long service life.

Thanks to the high quality of the materials used and the robust construction of our product range, the maintenance of our linear chains requires only regular lubrication.

Lubrication intervals depend on the operating conditions, such as working speed and temperature.

It is important to check all moving parts for signs of wear and then evenly distribute oil or grease over the entire chain using a brush. You can use commercial lubricants or greases that can withstand the demands. We recommend using a synthetic oil/grease such as Mobilith SHC PM from Mobil or a similar product. Alternatively, a commercial Teflon spray bottle is suitable.

Depending on the need, the linear chain can be equipped with a lubrication system (see below). This system uses an automatic lubricant dispenser from PULSARLUBE, model series E, available in various sizes (60 / 120 / 240 ml). The dispenser is filled with synthetic high-performance chain oil RIEDEL R-5550 with NSF H1 approval. The lubricant dispenser's delivery rate is adjusted according to requirements, and operation follows the manufacturer's instructions.

5. HMC (Basic version)

The screw jacks are factory-equipped with long-term lubrication based on oil. Under normal usage, it is recommended to lubricate the spindle after approximately *500 double strokes.

*This value varies depending on factors such as usage duration, load, temperature, speed, and stroke length. For specific situations, we offer personalized advice.

For basic versions with a square tube rotation prevention, the lubrication cycle described above should be observed depending on the duty cycle.

In addition to annual maintenance, it is recommended to replace the entire oil volume every 1000 operating hours or every 5 years. Before adding new oil, the gearbox should be thoroughly cleaned.

7. High-speed screw jacks (Basic version)

Our high-speed screw jacks are delivered with long-term lubrication as standard. Depending on the type of spindle and input speed, different lubricants are used. For trapezoidal thread spindles with input speeds up to 1500 rpm, grease is used, while oil is standard for input speeds above 1500 rpm and for ball screw spindles.

Under average conditions, we recommend re-lubrication every 500* double strokes.

*The exact value depends on various factors such as duty cycle, load, temperature, speed, and stroke length. We are happy to advise you in edge cases.

Lubrication is provided through a grease nipple on the gearbox. Due to the wiping effect on the spindle, there may be a minor grease leakage, which is balanced by regular re-lubrication. If such grease leakage is not desired, the gearbox can be sealed. However, this requires separate lubrication of the spindle to avoid dry running.

In cases where high-speed screw jacks are difficult to access, lubrication points can be equipped with Perma bushings or connected to a central lubrication system.

For the basic version with a square tube rotation prevention, the described lubrication cycle should be adhered to depending on operating time. For models with a safety nut, we recommend checking the gap at least twice a year, which can also be done automatically by sensors if desired.

9. Electric cylinders

Lubrication of the male clevis and spindle: Our drives are delivered with long-term lubrication and feature a grease nipple on both the male clevis and the spindle.

For high switching cycles or vertical installation (spindle at the top or bottom), we recommend refilling grease every 3 to 6 months or after 500 double strokes in the extended position. The exact amount of grease can be found in the table below.

Depending on the application, it is advisable to periodically clean the piston rod with an oiled cloth.

9.1 Spindle wear

If you observe wear on the trapezoidal or ball screw spindle or the spindle nut, we recommend completely replacing these components with new ones from the manufacturer. Due to natural wear, particularly depending on load and stroke speed, it is advisable to order a replacement drive (exchange drive) from the manufacturer or an authorized distributor in advance.

9.2 Lubricants

Instead of the recommended lubricants, similar lubricants from other manufacturers may be used, provided they have comparable consistency and base.
