Tips To Prevent Polyurethane Caster Wheel Failure

Wheels and rollers in dynamic applications experience cyclic loading and unloading. When this occurs, the mechanical energy is converted into heat energy which causes the parts to heat up. If they have a polyurethane tread and the heat build-up is too great, the urethane could melt and cause the wheel or roller to experience blowout. This article will cover some ways to decrease the chance of polyurethane tread blowout in your industrial wheel application.


High Performance Poly for Heavy Duty Caster Wheel Applications

Generally in high speed and/or high load wheel and roller applications, special high performance polyurethanes are used for the treads. NDI and PPDI urethanes are most commonly used. Reaction Industries, An alternative product to the traditional is TODI polyurethane which may be unknown and has significant advantages over the traditional materials (www.reactionind.com). Extensive testing has been conducted which shows that the TODI urethane performs comparably to the NDI and PPDI urethanes studied, and at a significantly lower cost.


Four Tips to Specifying Polyurethane Drive Wheels, Industrial Wheels for Conveyor Caster Applications

A polyurethane caster wheel is a popular choice in many drive wheel applications. Drive wheels are used in many conveyor applications to advance items and in automatic guided vehicles to drive the vehicles. Polyurethane treaded drive wheels are a popular choice because they have good dynamic properties, good wear properties, and provide a high coefficient of friction. While polyurethane treads are commonly used in drive wheel applications, there is much to consider when designing the wheel for the application. This article will discuss the key considerations for properly specifying a polyurethane treaded wheel for a drive wheel application.


Five Reasons to Use a Polyurethane Caster Wheel in a Heavy Duty Industrial Wheel and Caster Application

Polyurethane caster tires are a popular wheel tread for use on industrial wheels, whether it is in a caster application or drive wheel applications. There are many great reasons to choose polyurethane caster tires for an industrial wheel or caster application. This article will discuss some of the reasons why polyurethane caster tires are a popular choice.


Polyurethanes Applications in Heavy Duty Industrial Casters and Heavy Duty Industrial Wheels

Caster flutter is a phenomenon in which a swivel caster is harmonically excited such that it begins to swing uncontrollably from side to side as the wheel rolls forward. Caster flutter results in excessive noise, increased wear on all bearing elements and loss of tracking and control of the dolly or cart in which the caster is installed. There have been numerous studies to understand the causes of caster flutter. The three most common causes of caster flutter in industrial casters and wheels are:


Five Important Facts about Polyurethane Caster Wheels in the Heavy Duty Industrial Caster Application

The advent of polyurethane nearly 50 years ago has had an impact on many industries and product lines. One area that it has impacted significantly is the manufacture of heavy duty industrial casters and wheels. Approximately 80 percent of all heavy duty applications require a polyurethane caster tire applied to a wheel core. The quality of the material and process is what assures a long life cycle of the product.


Polyurethane Use In Industrial Caster and Wheel Applications for Heavy Duty Casters and Wheels

For most industrial wheel and roller polyurethane applications, the type of material can be chosen on the basis of hardness, load carrying capability, or other standard material properties. If necessary the properties can be altered by adjusting the chemistry during processing. This improves some qualities, but in turn diminishes others. There are some applications for which the selection of polyurethane requires more consideration. Here are a few examples:


Failure of Polyurethane Urethane Industrial Wheels Rollers in Heavy Caster and Wheel Applications

Failures of polyurethane or urethane treads on industrial caster wheels, drive wheels, and industrial rollers cost companies not only in money to replace the wheels but also in the down time of equipment. Many of these failures can be prevented. This article discusses the most common failures encountered in these applications and possible solutions to prevent or minimize failures.


Retreading Polyurethane Caster Wheels

Polyurethane caster wheel retreading is becoming a popular way to reduce costs and replace worn out polyurethane caster wheels in industrial applications. It also has some environmental benefits as well. If a company has industrial casters with worn polyurethane caster tires and the metal wheel cores are still in good shape, the wheels can be returned to have the old polyurethane and bearings (if equipped) removed and re-treaded with a new polyurethane of the user’s choice and new bearings. This is may well be less expensive than buying new industrial polyurethane caster wheels.
