Special roller bearings – Customised roller bearings for the most demanding requirements

SMG designs and manufactures custom rolling bearings that intentionally deviate from standard dimensions, geometries, and materials. Each bearing is engineered individually to meet the exact requirements of your application.
With our deep manufacturing capabilities within the Groz‑Beckert Group, we deliver durable, precise, and high‑performance bearing solutions made from engineering plastics and high‑performance polymers.

Custom rolling bearings are application‑specific components that differ from conventional catalogue bearings. They are used when standard bearings cannot meet technical, environmental, or functional requirements.

SMG offers full flexibility in design, geometry, material selection, and integration of additional functionalities.

Our customised roller bearings are designed to perfectly suit the respective application – regardless of whether high temperatures, aggressive media, special installation space requirements or additional functions are required.

SMG offers maximum flexibility in design, material and function.

Our customised roller bearings offer a wide range of technical customisation options:

We offer a wide range of engineering and high‑performance plastics tailored to environmental and mechanical conditions:

• Plastics with UV‑stabilizing additives
• High‑performance polymers such as:
  • PEEK (Polyetheretherketone) for high temperatures and chemically aggressive environments
  • PI (Polyimide) for extreme thermal and mechanical loads
• Materials engineered for:
  • Radiation environments
  • Chemical exposure
  • High‑temperature applications
  • Cleanroom or food‑grade environments

For applications requiring higher load capacities, we offer:

• Two‑row and multi‑row ball bearing configurations
• Increased static and dynamic load ratings

• Tailor‑made for the exact needs of your application
• Integration of additional functional elements possible
• Excellent performance in high‑temperature or chemical environments
• Lightweight, low‑friction, and maintenance‑friendly
• Cost‑efficient through optimized material selection
• High precision and stable quality through manufacturing within the Groz‑Beckert Group

SMG custom rolling bearings are used in a wide range of industries:

• Packaging machinery
• Food and beverage industry
• Medical technology
• Water and fluid management
• General mechanical engineering
• Chemical industry
• High‑temperature or radiation‑exposed environments

We design and manufacture the ideal rolling bearing for your requirements – including geometry, material selection, and optional functional integration.
