Heavy Duty 5 Pipe Track Wheel Cold Rolled Hardened Steel Sealed Bearings / Maintenance Free 2" wide with 1-5/8 Pipe Slot Weight Rating - 6000 lbs 5/8 Dia. X 6 Bolt Maintenance Free Zinc Plated Finish
We use the sealed bearing wheels in locations that is far from our shop because they require low maintance.
I was sick of my gate binding as the gate rollers were always sagging. The $30 gate rollers I was replacing yearly just didn't stand up. These are pricey but made to last the bearings in these are HEAVY duty. Well worth the investment.
No more gate trouble after installing these wheels.
