Production Process
All Rexnord chain parts undergo extensive quality treatments to achieve maximum operational safety and optimum performance. - High case-hardening
- Shot-peening
- Ball-drifting
- High pre-loading
- Construction of seam-free rollers
| | Process | Benefit | High Case Hardening | 
| Pins and bushes that make up the chain-bearing area are furnished with an optimally deep hardness layer.
| Lengthening of working life
| Shot-peening | 
| All pins, plates, bushes and rollers are shot-peened.
| Fatigue strength is further improved. Surface is compressed and load-bearing characteristics are increased.
| Ball-Drifting | 
| Ball-drifting of the plate boresAll punching flutes and sharp edges are simultaneously removed.
| Strain-hardening of the material Significant improvement of the press fits and the fatigue strength of the chain
| Pre-loading | 
| Chain undergoes severe length control Subjected to a high tensile load
| Enhancement of load-bearing property and reliability Minimizes initial stretch that all chains experience during the first hours of use Reduces expensive tensioning in application
| Seam-Free Rollers | 
| Seam-free rollers protect the bushing against shock impacts and the working face of the tooth against wear.Rexnord rollers are manufactured to high precision, with uniform wall thickness and absolutely free of any taper.
| Outstanding load-bearing areasmooth, quiet running
