Q Selection based on temperature Selection of Stainless Roller Chains for High-Temperature Operation
1 Follow the specification selection for low-speed operation up to 400˚C. (Do not
Selection of Roller Chains Based on Temperature use the specification selection method for operation under normal conditions.)
The following table shows selection criteria for roller chains by size 2Above 400˚C, use the temperature coefficient described below.
based on temperature and the associated reduction in strength. 3Formula
1) Problems associated with roller chain operation at high temperature
1Reduced hardness and resultant increase in wear Max. Working × Application Coefficient × Speed Coefficient × Temperature Coefficient ≤ Max. Allowable
2Elongation due to softening Tension on Chain (Table 1) (Table 4) (Kt) Tension of Chain
3 Poor lubrication and flexing and wear increase due to oil deterioration and Temperature Coefficient(Kt)
carbonization Temperature Coefficient(Kt) Take account of
4Wear increase and poor flexing due to scale 400˚C Less 1.0 corrosion resistance,
