Medium Heavy Duty Casters - Series 30

mwedium to heavy duty casterNational Caster's Series 30 heavy duty casters feature a rugged construction with double ball bearing heat-treated raceways. A tough zinc plating protects the 1/4" cold forged top plate and yoke. The top plate and yoke assembly are joined by a 5/8" bolted kingpin.

Wheel axles are 1/2" diameter bolt with lock nut. A 3/4" roller bearing allows the wheel to rotate freely. Hardened spanner bushing with grease groove, and grease fittings in swivel raceway and wheel provide easy maintenance for this medium heavy caster.

Applications for Series 30 Heavy Duty Casters

A versatile caster with a bolt on top plate (welding possible) able to handle a variety of applications. Material handling chores, such as platform trucks, warehouse carts, stock picking trucks, and freight terminal usages are easily handled by the Series 30 casters. This caster also ideal on food service carts, and hotel and housekeeping carts. Overall, an excellent choice for machinery dollies, and industrial and commercial equipment.
