Product Description

SPD Rubber Disc Roller Description :

Our Impact roller two 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.

Cheap Inferior idler means:
Inflexible movement and more power to run $$$ Quicken the wear and tear of belts $$$
More placement(Be one year or just two weeks to go)$$$
More downtime for maintenance$$$
Inferior roller brings harms, endless ....
Inferior roller means low buying price, high running cost.
