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.

• HEAT-TREATED MOVING PARTS.All moving parts are hardened to a precise molecular depth and Rockwell hardness. Thisextends caster life under rugged conditions andshock loads.

• RACEWAY DUST CAP. Dust cap protects the raceway from

contamination by dust, dirt, moisture, andother environmental debris. Whilestandard on 50 series casters, these are

usually not available on most competi-tive brands.
