The ZEN Group Renames its European Branches



It has taken many years of substantial work and considerable investments in state-of-the-art technology since the ZEN group was established in Dusseldorf, Germany, in 1992.

At this present time, with an extensive catalogue with more than 6,000 product lines, 3 factories, 6 warehouses around the world, and a presence in more than 18 countries. The company has decided to take a step forward in its consolidation as a global bearing manufacturer, presenting itself to its customers as a single entity.

It is for this reason that, from October, the names of its European branches are going to be changed as follows:

  • E. Eisenberg & Co. GmbH to ZEN Wälzlager GmbH.
  • PBI International Ltd to ZEN Bearings UK Limited.
  • Rodaplus SL  to ZEN Rodamientos SL.
  • Rodaplus SARL to ZEN Roulements France SARL.

About the ZEN Group. 

ZEN Group is a bearings manufacturer according to German DIN quality standards for a wide range of industrial applications. 

The group´s three production plants in China distribute their products globally through their robust distribution network.

Quality is what defines ZEN Bearings. It is a mindset for all members of their team, and it is integrated through each step of their manufacturing process, from the sourcing of their raw materials right through to the aftercare once the product has been delivered to you.

ZEN Group´s ISO 9001 certified quality control centre is a crucial part of delivering high-quality bearings. Only this facility covers more than 5,000 square meters. It features state-of-the-art testing equipment and a great team of highly qualified inspectors working every day to ensure a high level of quality.

ZEN’s Bearings quality control process involves numerous procedures during and after the production of the bearing. All of them, as well as their tolerances, are set to DIN Standards, certificated by the German TÜV.

  • Material inspection: A gas chromatograph allows testing of all types of steel for quality and composition accurately, before and after production.
  • Visual inspection: Time-consuming and often undervalued, but an expert eye often helps to detect material or assembly faults, that mechanical test equipment cannot find.
  • Dimension Testing: A rigorous tolerance check is performed on all bearing dimensions to guarantee that the products are according to the DIN standards.
  • Noise Testing: Highly sensitive microphones measure and identify audible peaks of a rotating bearing. These peaks can indicate faults to the raceways or possible grease pollution.
  • Vibration Testing: Using high, medium and low range frequencies, the vibration test can identify a range of bearing defects, such as imbalance, play and misalignment.
  • Radial and Axial Clearance Testing: Our machines are calibrated regularly to ensure the tolerances adhere to DIN standards certificated by the German TUV.
  • Hardness Testing: The Rockwell test determines the hardness of the material by measuring the depth of penetration of an indenter under load after hardening.
  • The salt spray test:  is a standardized test method used to check the corrosion resistance of materials. It is an accelerated corrosion test that produces a corrosive attack on the tested samples to predict their corrosion resistance. The appearance of corrosion products (oxides) is evaluated after a period of time. Test duration depends on the corrosion resistance of the material. The more corrosion-resistant the material is, the longer the period in testing without showing signs of corrosion. The standard testing period for ball bearings is 120 hours.

In addition to the DIN standards and the ISO 9001:2015 protocols, they implement their own checking procedures in their Chinese premises and global warehouses. This way, they ensure that the bearings are in perfect condition throughout the production and distribution.
