- Wheels for high temperature rooms
- Types of fasteners
In any industrial enterprise, various types of carts are used to move products. The cart design always includes some kind of wheels. The materials for their manufacture are different and depend on the field of application, environmental conditions and physical stress on the assembly.
There are two types of wheels: with an axle and an independent fastening of each wheel to the base of the cart. The second option is carried out using bearings and screw fasteners to the bottom of the bogie. The materials for the manufacture of wheels are steel and cast iron, polyurethane. The tires are rubber or nylon components of various thicknesses.
Wheels for high temperature rooms
In bakeries, confectioneries and smokehouses, carts have wheels made of special alloys. The fact is that in such premises, auxiliary equipment must withstand prolonged exposure to high temperatures, up to three hundred degrees Celsius. In addition, such wheels must withstand sudden temperature changes up to minus forty degrees, for example, when removing bread from the oven to an open overpass for cooling.
Cast iron wheels with roller bearings and stainless steel fasteners are suitable for such bogies. For example, the St. Petersburg trading company "WheelsRoliki. SPB" site https://kolesaroliki-spb.ru/kolesa-dlya-pechej.html offers high quality heat-resistant wheels at an affordable cost. The assortment is presented in various modifications.
Main technical parameters of products:
- wheel diameter, 80 - 100 millimeters;
- bottom landing height, 106 - 127 mm;
- type of built-in bearing, ball or sliding;
- lifting capacity of one wheel, 120 - 140 kg.
If you are already using self-leveling floors or tiles in production, and the temperature in the oven reaches 300 degrees Celsius, we strongly advise you to buy special heat-resistant cast iron wheels.
These wheels treat high-quality self-leveling and tiled floors with care. But do not use them on old cast iron flooring and metal corrugated sheets. Such imperfect floors can finish off the polymer thermo wheel over time. Use aluminum or cast iron wheels on metal floors. If the temperature range in your production is 250 degrees with a possible short-term increase up to 300 degrees, but not higher.
The main thing in heat-resistant wheels is the material of manufacture. It depends on it in what temperature range they will serve, to which chemically aggressive environments they are resistant, and also how safe they are for floor coverings.
Cast cast iron wheels are a classic solution. They are able to withstand temperatures above the recommended + 300 ° C and serve for many years. The only important nuance in application is the strength of the floors. Hard cast iron can damage tiles and other brittle or fragile floor coverings. Simple plain bearings are installed in the axles of cast-iron wheels, which must be periodically lubricated with heat-resistant compounds. Plain bearings are durable and resistant to water and shock.
Types of fasteners
Heat-resistant wheels are mounted to trolleys by means of steel brackets with platform fastening (platform with four holes). As they face extreme temperatures, heat shock and high humidity, the brackets are reliably protected against corrosion by a double zinc coating. Models with stainless steel brackets can be ordered if required.
The swivel unit of the bracket contains a double ball bearing with heat-resistant grease and a sealed housing to prevent the ingress of dust and dirt.
If there are any difficulties in the selection of the wheel design, the buyer can contact the professional consultants of the online store through electronic feedback or contact phones. All mechanisms use a specialized heat-resistant lubricant, which increases the comfort of using the bogies and the durability of the entire structure. Wheels have a manufacturer's warranty period, which is very important.
