Precision sealing
for Mining & Quarrying Equipments
A Crusher Shutdown Brings the Entire Process Line to a Halt
The hydraulic systems that control crusher gap adjustment are subjected to significant pressure loads with every setting change. At the same time, vibrating screen motors generate continuous vibration that places constant stress on their seals. A leak in any of these systems can halt the entire installation, causing downstream conveyors and screens to stop due to a lack of material flow.

Our Precision Sealing Solutions
O-Rings
O-rings are used throughout fixed sealing interfaces across processing installations, from hydraulic power unit connections to gearbox housings. Their simple circular design minimizes assembly errors, while the controlled deformation of the seal cross-section under compression creates an effective and reliable sealing barrier.
We offer a broad range of elastomer families and hardness grades, allowing each seal to be matched precisely to the compression loads and operating conditions of your application.
Rubber-to-Metal Bonded Seals
These seals address one of the most critical challenges in heavily loaded hydraulic systems: ensuring reliable sealing beneath bolt heads and within threaded fittings.
Our design combines a rectangular-section metal washer with a bonded and vulcanized trapezoidal rubber sealing element. A thin centering membrane facilitates accurate positioning during assembly.
This construction provides outstanding resistance to both pressure and vibration, making it particularly well suited to crusher adjustment hydraulic circuits, where both stresses occur simultaneously.
Compounds for Harsh Operating Environments
The choice of elastomer compound has a direct impact on the service life of a seal. NBR and EPDM materials meet the requirements of many standard applications, while HNBR compounds provide enhanced resistance in systems exposed to hydraulic oils.
For installations operating at high altitude or in extremely cold climates, we can recommend low-temperature FKM compounds that maintain sealing performance under challenging environmental conditions.
