Because you deserve better performance from your investment!

Problem

Does your portable crushing and other high abuse equipment suffer from product entrapment that punctures your expensive belts resulting in costly repairs or premature belt replacement? Excessive cover abrasion? Premature gouging and wear?

Solution

Yokohama PROTEX with UR Covers. Designed to be virtually “Maintenance Free” belts for portable quarry crushing and other high abuse equipment, PROTEX belts give you greater peace-of mind with the lowest cost per tonnage and best ROI on the market today.

Yokohama PROTEX features a special polyester fabric with elongation at break 1.8 times higher than Nylon fabric. Nevertheless, belt stretch under operating tension is less than that of conventional polyester fabric belts.

Yokohama PROTEX belts with UR Covers

UR covers were initially developed by Yokohama to handle heavy limestone rock before and after primary crushers. UR cover belts have succeeded in improving belt life with superior impact and gouge resistance features superior to that of RMA-1 cover belts.

Comparison of impact resistance with UR covers

PROTEX belt absorbs impact like no other belts.

PROTEX BELTS = TOUGH, FLEXIBLE, AND LOW-STRETCH
  • ・ Excellent resistance against trapped material & cake build-up on pulleys
  • ・ Excellent impact resistance and cut & gouge resistance
  • ・ Superior abrasion & wear resistance under extreme conditions
  • ・ Less permanent elongation & belt stretch
  • ・ Best choice in rough operating conditions. ie Portable Cone & Jaw Crushers

Let us show you how Yokohama PROTEX belts can take the abuse & deliver!
