Product Spotlight: 6803 & 6809 Caster Series

Heavy Duty Engineering

With up to 1,500 lbs. of brute strength, our 6803 and 6809 Series casters were built to perform and can take on just about any heavy-duty application. Featuring legs that are 2-1/2” wide, which is 1/2” wider than those on most other casters, these series are a true feat of engineering.

6803 Series

A number of features contribute to the durability of the 6803. Wider legs provide more contact with the washer. These casters are stamped, and then work hardened, adding to their durability. Finally, the 3/4” kingpin makes them incredibly sturdy.

This caster also features outstanding versatility, including diameters that range from 4” to 8” with 2” tread widths. A hard-to-find 2-1/2” width, with double welded legs, is available on 6” and 8” casters. 10” and 12” diameters are also available on request. While the standard overall height is 9-1/2”, a 9-3/4” version can be ordered. The 6803 can be produced with a wide range of wheels, brakes, stems, bearings and plates.

6809 Series

There’s also a stainless-steel version of this caster – the 6809. It’s made from work-hardened, electro-polished, de-magnetized and de-burred SAE 304 stainless steel. The 6809 is a complete stainless-steel caster including the axle, bearings and raceway balls.

NSF-Approved, this caster is corrosion resistant, moisture friendly and perfect for healthcare, pharmaceutical, food production, server-rooms and other clean applications.

Stainless Steel: 304 or 316?

Stainless steel resists rust and corrosion while preventing scaling, and that makes it the ideal solution for casters being used in wet, outdoor, clean and high-temperature environments. Once you’ve decided on stainless steel, you then have the choice of 304 or 316-grade stainless. In this issue of CasterU, we give the information you need to make the right decision.

6809 Series: S6859-A45H-MPU-RB [304 Stainless Steel]

Stainless steel is actually a mixture of steel and a minimum of 10.5% chromium. The chromium keeps the steel from oxidizing, rusting, corroding, and eventually staining, so it really is stain-less.

304-grade Stainless Steel
The most common grade of stainless steel is SAE 304. “SAE” is the Society of Automotive Engineers, the organization that standardizes and designates various grades. 304 Stainless steel contains 18% chromium and 8% nickel. When used in casters, it is:

  • Work-hardened – steel that becomes stronger and harder through a bending and forming process
  • Electro-polished – Untreated stainless steel has a very dull look. Because super-clean items are expected to be brilliantly reflective, we electro-polish our stainless steel casters.
  • De-burred – After being stamped, stainless steel components often have razor-sharp edges that can be a hazard. We de-burr the material to ensure no one gets hurt.
  • De-magnetized – Stainless steel is often used in laboratories and environments containing sensitive equipment. De-magnetizing minimizes the impact on the surroundings.

Many Algood casters and wheels are available in 304 stainless steel and come with a full range of stainless steel components.

316-Grade Stainless Steel
316 Stainless is made up of 16% chromium, 10% nickel and 2% molybdenum. There’s a little more nickel and a little less chromium than in 304. However, the big difference is the molybdenum, a chemical element used for the strengthening and hardening of steel. The higher molybdenum content greatly increases the corrosion resistance of 316, providing superior resistance to chlorides and acids.

That makes 316 an ideal upgrade for technology production facilities that require an environment that is free of any contaminants. It’s also ideal for settings with strict hygiene and cleanliness standards, like pharmaceutical, hospitals and healthcare locations. Since sterilization processes in these industries combine both strong disinfectants with high temperatures to prevent contamination, a resistant alloy like 316 is ideal. 

Our Maxx9 and 7009 series casters can be produced using 316-grade stainless steel

Other applications for both 304 and 316 stainless steel include:

  • Chemical processing and storage equipment.
  • Refinery equipment
  • Medical devices
  • Marine environments, especially those with chlorides present
  • Medical equipment and implants
  • Foodservice, processing, and preparation environments
  • Coastal environments
  • Areas with high salt levels (such as roadways)
  • Brewing facilities
