Explanation of Symbols
Profiles symbols for selection tables
Arc segment profile
- Slide profile shape with optimum mechanical properties
- Simultaneous contact with several rollers
- Optimum chain protection
Return profile
- 180° change of direction
- The 180° change of direction permits the dual use of longer tension distances.
Block profile
- Suitable for particularly heavy chains and high mass forces
- Slide profile and tension core made from a single piece
- No screw connections
- Excellent stability
- 300 mm slide profile ensures support for many rollers with chains with large chain pitches
Semi-circular profile
- For 90° deflection
- Contact with only very few chain rollers
- Recommended where space is at a premium
Roller/sprocket
- For small changes of direction
- For high chain speeds ( > 1 m/s)
