High Temperature Caster Wheels

 

High Temperature Caster Wheels

Industrial caster wheels for high temperature have made of material that supports the high temperature. Caster wheels are categorized as high temperature where they able to function normally at temperatures above 150° F (66° C). Standard caster wheels or regular industrial caster wheels when used at temperatures that exceed the provisions could result in damage, short operating life, increased maintenance or premature failure. In industrial the high temperature caster wheels widely used such as in autoclaves, bakery oven, curing oven, powder coating, and smokehouses or around water steam.

High Temperature Caster Wheels

Below a description of the wheel materials that is often used to high temperature caster wheels:

  1. Polyurethane wheels. High temperature caster with polyurethane wheels usually use for below 180° F or 82° C application, when use nearing 180° F polyurethane wheels will weaken and must proper evaluated.
  2. Nylon wheels. Up to 250° or 121° C can withstand by nylon wheels and other type of proper nylon wheels can withstand intermittent temperature up to 400° F or 204° C. Most people like use the nylon wheels because with minimal force can roll nylon wheels.
  3. Phenolic wheels. They have material proper made out of fiberglass. You can use these wheels for high temperature up to 450° F or 232° C but non continuous condition maximum for 30 minute. Regularly many people use these casters for dry heat application such as for powder coating trolleys, bakery oven trolleys and dry heat autoclaves. When use for more 30 minute the life of wheels reduce.
  4. Cast iron wheels. When you want to use trolleys for temperature up to 600° F or 315° C, choose cast iron wheels are the right choosing. These wheels also have high load capacity but they can increase wear on the floor surface.

Don’t forget except wheels, high temperature caster wheels must be having brackets with high temperature.  However regularly casters from steels or stainless steel can withstand high temperature, but there are some things to watch. Lubrication, on swivel section bearings needs lubricating that applicable for high temperature. The proper lubrication must be according with this application, because if not effectiveness of the lubrication will be loss when used exceed work temperature of the lubrication. Lubrication for high temperature caster wheels is from specialized greases to dry film and graphite lubricants. Lubrication also need for bearing of the wheels section, they have high factor for life time of the wheels.
