Frequently Asked Questions
FAQ – Quick Answers
What is the most commonly used pitch dimension?
40×40 mm (NNK® ISP 40) is the universal standard in mechanical engineering – available in light, medium and heavy, 8 mm groove width, extensive accessories from multiple manufacturers.
Is there a rule of thumb for choosing the pitch dimension?
Yes: load per column up to 200 kg → 40/45 mm. 200–500 kg → 60 mm. 500–1,000 kg → 80 mm. Over 1,000 kg → 120–160 mm. These guidelines apply to medium column lengths and must be calculated for the specific load case.
Can different pitch dimensions be combined?
Yes, with transition connectors and adapter plates. In practice however, pitch changes within a construction are avoided as accessories are not universally compatible. Recommendation: choose one pitch dimension per construction.
What does "light", "medium" and "heavy" mean for profiles of the same pitch dimension?
These designations refer to wall thickness and cross-section geometry: Light = thin walls, minimum weight. Medium = standard mechanical engineering. Heavy = thick walls, maximum load capacity. All variants have the same external dimensions and can be assembled with the same accessories.
