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.

Ideal Applications

Configuration Note: For maximum maneuverability, use four swivel casters (allows movement in any direction). For straight-line stability with steering, combine two swivel (front) and two fixed (rear) casters.
