Tribology and lubrication
We evaluate friction, wear and oil-material compatibility to analyze bearing surface behavior and lubrication margin.
R&D CENTER
Engineering-driven innovation in engine bearings and bushings
We develop multi-layer plain bearing and bushing solutions for application requirements by combining tribology, material science, design simulation and validation testing.

ENGINEERING INSIDE THE PRODUCT
Every layer is selected for its operating condition
Bearing and bushing performance is not defined by one material. The backing, bond layer, running surface, geometry and oil film work as one system, and our development decisions consider the whole system.

OUR APPROACH
From application to laboratory, from laboratory to production
Performance in engine bearings and bushings is defined by evaluating material selection, geometry, lubrication conditions and duty cycle together. Our R&D center operates with this holistic perspective.
Like R&D organizations at leading bearing manufacturers, we run application analysis, material characterization, prototype development and validation testing in an integrated process. The goal is to reliably define the right bearing solution for each engine and operating condition.
For crankshaft, connecting rod, camshaft, piston pin and auxiliary shaft solutions, we address both serial production needs and project-based custom development with the same engineering discipline.
COMPETENCIES
R&D disciplines dedicated to engine bearings and bushings
Material science and metallurgy
We examine bond interface, microstructure and surface properties in multi-layer structures such as steel-backed bronze, aluminum-tin and white metal.
Design and simulation
We assess design alternatives before application through load-speed diagrams, clearance tolerances and thermal behavior.
Prototype development
We materialize solutions through rapid prototype production and pilot trials from custom geometry, OEM reference or samples.
Testing and validation
We validate prototype performance before serial production with material, dimensional, metallurgical and endurance-focused tests.
Application engineering
We align bearing/bushing selection with customer and OEM requirements based on engine type, duty cycle and assembly conditions.
