12B-2 GL ReXtreme roller chain

Maintenance-free roller chain according to the European standard. Thanks to the maintenance-free nature, re-lubrication or maintenance of the chain is no longer necessary. This is ideal especially in applications where chain maintenance is difficult, for example due to the location of the chain or the possibilities for re-lubrication are otherwise limited. Available in chain sizes 08B, 10B, 12B and 16B in both single and double rows.

Features and benefits:
- Extremely long service life even without re-lubrication.
- Maintenance-free means that re-lubrication is not required, which makes it easier especially in applications where the possibility of maintenance is limited.
- High tensile and fatigue strength.
- Very good corrosion resistance up to 120 hours.
- Operating temperature range -5°C - +250°C.
- High energy efficiency.

The most important dimensions and markings for chain identification:
- p=pitch (mm)
- d1=roller diameter (mm)
- b1=inner width/roller width (mm)
