4 Inch Black Color High Quality PP M12*30 Double Ball Bearings Swivel Caster - Easy Assembling For Equipment
Functional Benefits
-
Effortless Mobility – The 4" diameter and double ball bearings dramatically reduce rolling and swiveling friction, allowing heavy equipment to be moved and turned with minimal effort.
-
Superior Maneuverability – Full 360° swivel action enables instant direction changes and tight-space navigation, ideal for crowded work areas.
-
Smooth Load Handling – Double ball bearings (in both wheel hub and swivel raceway) distribute loads evenly, preventing wobble and ensuring stable rolling even under rated capacity.
-
Quick Installation – Pre-assembled M12×30 threaded stem with lock nut allows tool-free or simple wrench attachment to equipment legs, frames, or mounting plates.
-
Durable & Low Maintenance – High-impact PP wheel resists cracking and wear. Sealed bearings reduce dirt ingress, minimizing lubrication needs.
-
Chemical & Moisture Resistance – PP construction withstands exposure to oils, solvents, and water, making it suitable for wash-down areas and laboratories.
-
Floor Friendly – Non-marking black tread protects tile, epoxy, and sealed concrete floors from scuffs and scratches.
