Heavy Duty Industrial Casters - Zinc Plated Steel - 66 Series

Our 66 Series Heavy Duty Casters are the workhorses for most industrial applications and heavy consumer applications. These industrial casters are rugged enough to be used daily and a very popular caster for consumers with those BIG projects around the house or office. They are available with 4", 5", 6" & 8" diameter wheels in a variety of different wheel materials. All of these wheels have a tread width of 2" for added capacity and durability. Our TLB Brake Option, which has the pedal on the side of the wheel, is available on both the swivel and rigid casters. Also available as an option on these industrial swivel casters is a "Position Lock" ( commonly called a swivel lock ) which locks the caster in one of 4 positions so it will not swivel. Each "notch" is 90 degrees apart so the "swivel" caster can actually function as a rigid caster when the lock is engaged in the desired position. A very handy option when both mobility and the ability of pushing in a straight line is required in your application.
  • High Capacity Casters up to 900 lbs each caster.
  • Case hardened double ball raceways provide extra capacity & durability.
  • Top plate and legs are made out of 1/4” cold forged steel.
  • Corrosion-resistant zinc plated finish.
  • 5/8” nut and bolt kingpin, 2-1/2” fork spacing.
  • 1/2” zerk axle & lock nut
  • Zerk fittings also in swivel bearings & most wheels.
  • Polyurethane on Aluminum, Rubber on Aluminum, Thermal Plastic Rubber and Polyurethane wheels do not mark floors.
  • Polyolefin Wheels are designed for storage racks which are not moved frequently. They can carry heavy loads without the fear of developing flat spots.

Hints
There is a lot of information on this page. Don't let it confuse you. Use this information to determine 3 things.
1. The type of wheel material that you need for your application. Put your mouse over the large wheel photo to see specifications.
2. The type of attachment that you require. Look for the diagrams of the plate sizes or stem sizes.
3. The size of the wheel and the style of the brake if you require a brake.

Most photos on this page can be enlarged by clicking on the photo.
Used On:

Miscellaneous Carts - Platform Trucks - Wire Shelving Units - Heavy Appliances - General Duty Material Handling - Vending Machines - Warehouse & Factory Applications - Heavy Food Service & Institutional Equipment - Textile Applications - Tool Boxes, etc.


The most important decision when selecting a general duty caster is the type of wheel material to use. The following are the factors to consider: Floor Material and Surface, Weight and use of object. Always choose more capacity in the casters than the maximum amount of weight that will be needed. For most objects, figure the weight of the object and divide by the number of casters that you will install. As a rule of thumb, add 20% to that amount for safety. For objects that will be sitting in one place for long periods of time, either a hard wheel should be used or a softer wheel with twice the capacity for the weight that it will hold. Softer wheel materials may be required to protect floors but those wheel materials have a tendency to develop flat spots from sitting in one place for long periods of time. By only using half of their capacity, the wheels should not develop flat spots.
