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!

- Customer application
Today, we would like to introduce you to one of our customers who specializes in manufacturing horizontal directional flush drilling rigs. These rigs are used for laying natural gas and distribution networks as well as fiber optic lines and many other applications. - Customer problem
There is a potential hazard to the lubrication nipples that are typically driven into the shaft side. During lubrication, there is a possibility that these nipples could be pushed out, which would result in lubricant leakage. Since this area is not accessible and visible due to the closed housing, such leakage could go unnoticed and lead to 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 grease nipple could not be pushed out by mechanical load during lubrication. Thanks to precise planning and detailed analysis, a solution was found that ensures maximum functionality and reliability. - Solution
An effective solution was found by replacing the impact grease nipple with a thread in the bolt. The grease nipple could now be securely screwed in place, ensuring smooth operation. - Customer benefit
Our new product update not only offers our customers enormous time savings in mounting and lubricating the stud type track roller, but also increases the service life of the bearings. By avoiding grease leakage, a sustainable use of resources and thus a contribution to environmental protection is made. We are proud to offer our customers not only the best possible quality, but also an environmentally conscious product.

Cylindrical roller bearings for construction machinery
For effective soil compaction on medium-sized areas, the vibratory plate is an indispensable tool in the construction industry. Since the 1950s, it has established itself as standard equipment on many construction sites. There are both independently forward running and reversing machines that are used as needed. Typically, vibratory plates are hand-operated, while road rollers are used for larger areas. For smaller areas, on the other hand, vibratory rammers, also called vibratory tampers, and vibratory screeds are suitable for compacting concrete.
The vibratory plate is a machine driven by one or more shafts with integrated unbalances. These generate both the locomotion and the compaction effect of the vibratory plate through centrifugal force. The centrifugal forces are much higher than the weight of the machine and lift it briefly a few millimeters off the ground with each revolution of the unbalances. This moves the plate forward or backward and compacts the material underneath it with high surface pressure due to the built-up kinetic energy and centrifugal force.
Fröhlich & Dörken always strives to find ways to reduce costs - without compromising the quality of our products. Particularly in this special application, very high quality must be guaranteed. We therefore focus on continuous improvement of our products to ensure longer service lives. At the same time, we optimize our manufacturing processes 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, were able to reduce the price by 30 percent without sacrificing quality. Our many years of experience in co-engineering and our own quality assurance are the guarantee for our success.
