Endurance™ Kingpinless-Style Casters
Series EC - Cap. to 3,000 lbs.

#S-EC-82AYB Swivel w/ Polylast™ Wheel


#R-EC-83FST
Rigid model w/ Forged Steel Wheel
The Endurance™ Series casters represent the “best of breed” in kingpinless-style design. The top plate and inner raceway are formed from one piece, providing a superior raceway for shock conditions. Once formed, the raceways are CNC-machined and then induction hardened to ensure a uniform depth in hardness of the swivel raceway. A sealing cap is welded to the outer race to assure protection from foreign material and to keep grease in the raceway.

All Endurance™ Series casters are finished in bright zinc plating and come standard with a choice of ten different wheel types. Standard bearing selections include double sealed precision ball bearings, precision tapered bearings, or straight roller bearings.


QUALITY FEATURES

EC Swivel Construction
Load Bearing – Induction hardened and CNC-machined raceway: 2 3/8" swivel diameter with 3/8" balls in 2" wheel widths and 3" diameter raceway with 1/2" balls in 3" wide wheels.
