4" V Groove Sliding Gate Rollers 2 PCS Heavy Duty 3000LBS Steel Gate Wheels

• HIGH LOAD BEARING: Constructed from premium 1045 solid carbon steel with gold electroplated finish. Each roller holds up to 3000 LBS, with a much larger load capacity than regular cast iron wheels to sustain long-term heavy-duty gate operation.

• DOUBLE SEALED BEARING CONSTRUCTION: Fully enclosed double-sealed bearings shield against dust, rain and corrosion. The maintenance-free design ensures stable performance outdoors amid damp, snowy and fluctuating weather.
• ACCURATE DIMENSION SPECIFICATION: Wheel diameter measures 4 inches, thickness is 1-3/4 inches, and the axle mounting hole comes in 0.51 in (13 mm) for standard M12 shaft installation.
• ALL-IN-ONE INSTALL KIT & EXTENSIVE APPLICATION: Each pack includes 2 x 4-inch gate rollers alongside matching M12×85mm bolts and gaskets for hassle-free DIY mounting without extra fittings. Perfect as replacement parts for residential wrought iron driveway gates, farm barn sliding doors, industrial workshop gates and custom machinery with V-type tracks.
