Description
This 4-inch by 3.25-inch 71 series caster has the highest load capacity rating in our line-up of single ball race swivel sections. The bearings in the swivel section act as both load and thrust components and lock the swivel section together to distribute the load over a larger area.
The wheels are constructed of premium Class 30 gray iron for maximum load capacity and impact strength. They feature heavy cross section castings for heavy duty use, abrasion resistance and a long service life. Each wheel is precision machined with rounded edges to finished tolerance. Packed with our straight roller bearings, which are most effective for heavy loads, and are a great option when facing excessive thrust loading, these casters are rated for 2000 lbs.
