SPD Impact Roller Description :

 

Our Impact roller 2 pieces  rubber-coated innovation technology 
 

New technology: using professional rubber and plastic machinery,

apply adhesive on roller tube, through high-temperature heating,

pressure, one-time whole casting adhesive. The radial run-out of the

roller keep stable, the adhesive force between rubber and roller is strong,

and the cushioning performance is excellent.
 

Old process: manually press the rubber ring into the roller tube, and

weld the retainer rings on both sides. The fit between the rubber rings

and the roller tube is an interference fit without adhesive. During the

operation, the rubber ring is easily forced to fall off, so the impact life

span could not be ensured, and the replacement and maintenance cost

is high.
