Grip ring stem casters—also known as friction ring stem casters—are designed for fast, press-in installation where access for a lock nut is not available. They are commonly specified for furniture, fixtures, carts, and light-to-medium duty equipment requiring a clean, compact mounting solution.
Typical wheel diameters range from 3" to 5", with load capacities up to 350 lbs per caster depending on wheel material and configuration.
The stem is inserted into a drilled mounting hole—most commonly 7/16" diameter. A spring-steel grip ring compresses during insertion and expands once seated, creating a secure mechanical retention inside wood, metal tubing, or composite legs.
These calculators apply to any caster application—even if you’re browsing a different category. Use them to estimate load rating per caster, select wheel material, and estimate push/pull force. Expand any tool for full analysis + a share-ready spec line.
