Heavy Duty Caster 4" x 2" V-Groove Steel Wheel — Series 40
This Series 40 medium heavy-duty caster pairs a 4" × 2" V-Groove steel wheel with a cold-forged steel top plate for guided, track-style material handling. The machined V-groove tread rides on inverted angle-iron or rail track, keeping carts on a fixed path under heavy load, while the double-row ball bearing swivel raceway, hardened raceways, and built-in Zerk lubrication fitting deliver smooth 360° movement and long service life. Each caster supports loads up to 900 lbs. Choose Swivel or Rigid from the menu above.
