Case Study: Urethane Roller Recovering Services
After investing capital into rollers, it’s quite frustrating when they break down. If you have initially invested in rubber or plastic rollers and thought they’d be long-lasting, but actually broke down quickly, you have a better option. While it’s best if the entire material is made of urethane, we do provide urethane roller recovering so that you can get your rollers back into tip-top shape again. What is Urethane Roller Recovering? As the name implies, urethane roller recovery involves taking your old rollers striping them and coating them in urethane. This is an incredibly affordable option since you wouldn’t need entirely new rollers, and is actually a best practice if you have your rubber or plastic wheels recovered with urethane regularly. Urethane is known for being highly durable with superior wear properties and lasts for a long time, which is why it makes a much better alternative to rubber and plastic. We are also able to process rollers through a secondary operation of machining and grind them down so that the urethane roller recovering coat we apply is as accurate as possible for close tolerance requirements. If you are looking for an affordable way of maintaining your equipment and want […]
