Engine bearings

Markets are changing more rapidly than ever, and environmental requirements and performance demands are evolving constantly. Around the world, manufacturers of high-performance diesel and gas engines face a variety of challenges.
Thanks to its international presence, the Engine Bearing Branch within Miba Bearing Group – as a specialist for engine bearing applications and production – offers its customers flexible and customized solutions. From development to choice of materials and exceptional application engineering, right through to logistics, we stand for innovative problem-solving skills when it comes to engine bearings.

Products & applications

Engine bearings are crucial components playing a significant role in engine function and service life. They help position crank- and camshafts, minimize friction during operation and protect the engine from damage and breakdown. By constantly developing new types of bearings, Miba ensures that modern engines are able to deliver maximum performance efficiently and in an environmentally friendly manner even under extreme conditions.

Over several decades, we have acquired in-depth knowledge of the tribology of engine bearings and the power train components that run on bearings. Thanks to our extensive experience in many areas, we are able to offer the right solution for every bearing application. Our strengths include independence from raw materials, highly advanced, reliable production processes and efficient quality management that is focused on meeting all functional requirements as cost-effectively as possible.

Hydrodynamic Plain Bearing Solutions

Hydrodynamic plain bearings are considered as technical enabler for wind turbine main gear boxes to meet future demands concerning power density increase, reliability and cost.
The reduction of levelized costs of electricity is becoming increas-ingly important. Our proven solution for this is hydrodynamic plain bearings, optimized for increasing torque density and limited installation space. Mixed lubrication capability is the key to a high performance product.

Advanced technology solution for highest load and speed

For radial bushings, we offer an inverse rolled solution with steel backing, combined with aluminum-based lining material and a Synthec® top layer that provides the necessary mechanical and tribological properties. This development has been tested many times, proven in field tests and is in series use.

We offer comprehensive engineering support, to enable our customers to switch from rolling element bearings to plain bearings

Research & development

As a technology leader, Miba has always sought innovative solutions. We focus on the needs of our customers who demand high-tech solutions at cost-effective prices. Our emphasis on research and development ensures that our products stay a step ahead and that they are precisely aligned with customers’ needs.

Years of experience in integrated product development means we can actively support our customers during engine development, for instance when bearings are designed, and when bearing simulations and operating risk analyses are conducted. Examples of this include providing test bearings, evaluating bearing performance as part of engine testing in state-of-the-art labs and conducting extensive tests in testing facilities. In this way, we are able to precisely estimate the expected service life for each individual bearing application.

Evaluation and service are carried out by employees at our own subsidiaries, at the customer’s location, or on site where the engine is in use. Our production processes for materials and bearings are state of the art, and we ensure that our customers are satisfied by providing reliable products with long service lives at competitive prices.
