Darnell-Rose 20 Series – Heavy Duty
Capacity Range: 350 – 1,000 lbs.
Engineered for the toughest applications, the 20 Series is the most heavily constructed caster in its class. Its robust design features a 3/8″ thick top plate, heavy welded yoke, and a precision-machined double ball bearing swivel raceway built to exact tolerances. A neoprene seal combined with a metal dust cap keeps out dirt and debris, ensuring smooth, long-lasting performance.
For added reliability, pressure lubrication fittings are standard in both the swivel fork and wheel axle bolt, simplifying maintenance and extending service life. Finished in bright zinc as standard, the 20 Series offers unmatched strength, protection, and dependability for heavy-duty service.

Quality Features
MACHINED CRAFTED SWIVEL RACEWAY.
Upper main load bearing consisting of top plate and base plate are precisely machined by CNC lathe to close tolerances and dimensions. The upper set of 3/8″ hardened steel ball bearings carries load weight, while lower set handles lateral thrust loads.
EXTRA-STRONG CONTINUOUSLY WELDED SIDE LEGS.
Yoke legs are formed from 1/4″ thick steel and made wider to handle constant abuse from side thrust. Fork legs are continuously welded to yoke base for added strength and endurance.
HEAT-TREATED MOVING PARTS.
All moving parts are heat treated to a precise molecular depth and Rockwell hardness using a gas carburizing process that extends caster life under rugged conditions and shock loads.
SEALED RACEWAYS WITH LUBE FITTING.
Upper raceway is permanently assembled with a neoprene grease seal. Bottom raceway is covered with a metal grease seal cap that is press fit then secured with Epoxy. Pressure fitting is provided for lubrication using conventional grease guns.
