Cylindrical Roller Bearings Made of High‑Performance Plastics – Precise, Durable, Maintenance‑Free

SMG cylindrical roller bearings made of high-performance engineering plastics combine high load capacity with low weight and completely maintenance‑free dry running. Compared to metal bearings or conventional injection‑molded plastic bearings, SMG bearings offer excellent friction behavior, outstanding corrosion resistance, and reliable performance even in challenging environments.

• Maintenance‑free operation
• Corrosion‑resistant, even against chemicals
• High radial load capacity
• Lightweight and energy‑efficient
• Low friction and smooth running
• Self‑lubricating, no grease required
• Custom‑engineered design – not standard injection‑molded parts
• Significantly more durable than typical molded plastic bearings

Instead of balls, cylindrical rollers are used as rolling elements, allowing the bearing to handle significantly higher radial loads.
The bearing design consists of an outer ring, inner ring, and cage, providing stable guidance and smooth, low‑vibration operation.

All SMG plastic bearings operate with a maintenance‑free dry running, eliminating the need for oil or grease.
Your benefits:

• zero lubrication, zero maintenance
• clean and hygienic – ideal for food, packaging, pharma, and water treatment
• resistant to moisture, chemicals, and aggressive media
• long lifetime with minimal wear

Every cylindrical roller bearing is individually engineered and manufactured according to your specific requirements.
We adapt:

• material combinations
• load ratings and speed requirements
• dimensional tolerances
• chemical and temperature resistance
• lifetime and wear behavior
