SERIES Quality Features• FOUR-SIDED, DOUBLE BALL RACEWAY.
Hardened steel ball bearings touch upper andlower swivel raceway “on all four sides.” Thisprotects the pin from shock loading for freeswiveling under heavy loads.

contamination by dust, dirt, moisture, andother environmental debris. Whilestandard on 50 series casters, these are
usually not available on most competi-tive brands.
