As experts in special rolling bearing solutions, we at Fröhlich & Dörken have already solved many a tricky problem. We can draw on extensive expertise, particularly in rolling bearing-based technology, and design a wide variety of special bearings. In one specific case, a change to the lubrication nipple proved to be the decisive solution. We are happy to assist you on site or in a TEAM meeting with our expertise and look forward to mastering your individual challenges!

- Application of the customer
Today we would like to introduce you to one of our customers who specializes in the manufacture of horizontal directional drilling equipment. These devices are used for laying natural gas and distribution networks as well as fiber optic cables and many other applications. - The customer's problem
There is a potential danger for the lubrication nipples, which are usually driven into the shaft side. During lubrication, there is a possibility that these nipples could be pushed out, which would cause the lubricant to leak out. As this area is not accessible and visible due to the closed housing, such a leakage could go unnoticed and lead to a failure of the bearing due to insufficient lubrication within a very short time.
- Solution approach
The technical challenge was to design the cam follower in such a way that the drive-in lubrication nipple could not be pushed out during lubrication due to mechanical stress. Thanks to precise planning and detailed analysis, a solution was found that guarantees maximum functionality and reliability. - Solution
An effective solution was found by replacing the impact lubrication nipple with a thread in the bolt. The grease nipple could now be securely screwed into place, ensuring smooth operation. - Customer benefit
Our new product update not only offers our customers enormous time savings when fitting and lubricating the cam roller, but also a longer bearing service life. By preventing grease leakage, we are making a sustainable use of resources and thus contributing to environmental protection. We are proud to offer our customers not only the best possible quality, but also an environmentally conscious product.

" Savings of over 30 %
" High-quality compaction of surfaces
Cylindrical roller bearings for construction machinery
The vibratory plate is an indispensable tool in the construction industry for effective soil compaction on medium-sized areas. Since the 1950s, it has established itself as standard equipment on many construction sites. There are both independently forward-running and reversing machines, which are used as required. Vibratory plates are usually hand-operated, while road rollers are used for larger areas. Vibratory rammers, also known as vibratory rammers, and vibratory screeds for compacting concrete are suitable for smaller areas.
The vibratory plate is a machine that is driven by one or more shafts with integrated imbalances. These generate both the movement and the compaction effect of the vibratory plate through centrifugal force. The centrifugal forces are significantly higher than the weight of the machine and lift it briefly a few millimeters off the ground with each rotation of the imbalances. This causes the plate to move forwards or backwards and compacts the material underneath it with high surface pressure due to the kinetic energy and centrifugal force built up.
Fröhlich & Dörken always strives to find ways to reduce costs - without compromising the quality of our products. Especially in this particular application, very high quality must be guaranteed. We therefore focus on continuously improving our products to ensure longer service lives. At the same time, we optimize our manufacturing processes in order to produce cost-efficiently. Our customers benefit from our co-engineering approach, which enables us to meet their specific requirements. We produce high-quality bearings at unbeatable prices and in one specific case we were able to reduce the price by 30 percent without compromising on quality. Our many years of experience in co-engineering and our own quality assurance guarantee our success.
