How often should rollers be reconditioned? Rollers should ideally be reconditioned every 6-12 months, depending on usage and wear. Regular reconditioning not only extends roller life but also ensures optimal performance and reduces the risk of downtime or costly replacements in industrial settings. Extend the Life of Your Rollers
The hardness of these rollers is between 65 and 80 Shc, with a higher hardness grade enhancing performance if used in line conditions. Figure 3 shows the metallurgical structure of the HCS roller. Fig. 3. Microscopic structure of the HCS roller; (a) 20μm zoom, (b) 100μm zoom.
