Lubricating greases

Keep things

Lubricating greases from Siebert are at home in almost every industry – and do their job reliably wherever strength and endurance are paramount concerns.

Siebert special greases prevent the penetration of dirt and water, guarantee lasting mobility and damp not only vibrations but also noise. In addition, many of our lubricating greases stand out due to their excellent environmental compatibility and biodegradability.

All our products have demonstrated their performance under extreme conditions. However, you may need a completely new product for your customers in order to meet special requirements. If so, why not benefit from our comprehensive expertise when it comes to developing new high-performance greases.

Our greases for the food industry meet NSF H1 requirements and can be produced with kosher and halal certifications.

This product range offers you a choice of:

  • antifriction and plain bearing greases
  • fluid greases
  • high-temperature greases
  • high-temperature pastes
  • readily biodegradable greases
  • noise-reducing greases
  • odour-neutral greases

Research & development

That doesn’t
exist yet

Researching and developing new products has always been part of our DNA. Take advantage of our innovative streak in order to improve the standing of your customers and your own market position with products developed specially for you – products that simply didn’t exist beforehand.

Our products are often high-tech tools that were developed to overcome new hurdles and challenges. In this context, our laboratory has always been the starting point for our success. It’s there that we develop suitable products for the respective customer specifications and requirements. This is also part of our job.

Over a fifth of our staff work is involved in research and development – carrying out basic research, preparing new formulations for stable fluid processes, and developing specific applications. As part of these efforts, we work closely with renowned universities and research institutes to ensure that intelligent concepts and new high-performance products regularly find their way to market for the benefit of our customers – and their customers.

How we set standards:

Metalworking fluids:

  • stable and highly efficient metalworking fluids
  • label-free metalworking fluids
  • user-friendly metalworking fluids: skin-friendly, odour-neutral and with sustainable properties
  • metalworking fluids that are free of amines, boric acid and formaldehyde

Special lubricating greases:

  • multi-purpose greases
  • high-load greases
  • high-temperature greases
  • lubricating greases for special applications
  • lubricating greases for the food, pharmaceutical and animal-feed industries (H1 registration optional)
  • Optional H1, kosher and halal certification
