300/301 Series

A rugged cold-forged caster, the 300 is designed to withstand severe shock load while providing a smooth swiveling action on hardened raceways. A precision top raceway, coined under extreme pressure, supports the load while a large diameter lower ball race absorbs the secondary thrust.

Applications:
For equipment in the range of 2000 to 6000 lbs. Suitable for heavy industrial and warehousing applications where high shock loads and severe operating conditions prevail.
