V-Groove Wheels - All Types

Diameter: 3 to 10 inTread: 1-1/4, 1-1/2, 2, 2-1/2, 3 inCapacity: up to 7,000 lb

V-groove wheels have a notched tread that sits on an upturned angle iron, which keeps sliding gates, doors and track carts in line. Cast iron sizes run from 350 lb at 3 in to 1,200 lb at 8 in, ductile iron from 1,500 lb to 7,000 lb at 10 x 3 in, and NyloForce polymer wheels carry 2,200 lb without rust. Match the groove to your track and the bore to your axle.

Iron, ductile or polymer

Cast iron is the low-cost pick for residential and light commercial gates. Ductile iron takes shock better, which matters on heavy gates that slam against a stop: at 6 in, going from cast iron to ductile lifts the rating from 1,000 lb to 3,500 lb in the 2-1/2 in width [S1]. NyloForce polymer wheels use 6205 sealed ball bearings and do not rust, listed for -40 to 250°F [S2], which makes them the quieter choice for gates near homes and offices.

Heat and weather

Cast iron V-groove wheels list -45 to 600°F and ductile iron -45 to 800°F [S1], so they work in kilns and heat-treat track carts as well as outdoors. Bare iron rusts outside, so paint or grease exposed faces and keep the track clean of grit.

Sizing a V-groove wheel

Measure the angle iron: a 90° angle needs a 90° groove, and the leg size should fit inside the groove.
Pick diameter: bigger wheels roll over debris on the track more easily.
Check bore, hub length and bearing on the listing.
For a gate, size for the full gate weight on the fewest wheels that touch the track at one time.

Gate setups: sliding gate wheels and casters. All rail wheels: track wheels.

V-groove wheel questions

What size V-groove wheel do I need for a sliding gate?

Start with the gate weight and the angle iron size. Light gates often use 4 to 6 in cast iron wheels, rated 350 to 1,000 lb. Heavy gates call for ductile iron, rated 1,500 lb and up.

Will V-groove wheels rust?

Cast and ductile iron will rust outdoors unless painted or greased. NyloForce polymer V-groove wheels are rust-free.

What is the strongest V-groove wheel?

The 10 x 3 in ductile iron V-groove wheel, rated 7,000 lb.

Can V-groove wheels run on flat floor?

They are made for angle-iron track. On a flat floor the groove carries the load on two thin edges and wears quickly.
