V-grooved track casters self-align on inverted-V steel rail — the wheel’s V-shaped tread groove rides the rail apex and gravity keeps the wheel centered, eliminating the wander and rail-walk that plagues flat-tread track applications. The 87 products on this page are predominantly Hamilton W-V Series (Iron V-Grooved) and EPSD/MD-FVT forged steel variants — capacity range 325 lb on the smallest 3″ stainless up to 10,000 lb per caster on the 10″ x 4″ EPSD-104FVT forged steel. Used for production-line conveyors, factory transfer carts, gantry crane runways, paint line tracks, and any application where the cart must follow a fixed path under load.

|---|---|---|---|---|
| W-V (Iron V-grooved) | 4″-12″ iron tread | Plain or roller | 325 - 3,600 lb | S-WW-4V (4″ swivel, 5/8″ roller) |
| FVT (Forged steel V-grooved Tapered) | 6″-12″ forged steel | Tapered roller | 4,500 - 10,000 lb | EPSD-104FVT (10x4 swivel 10k lb) |
| MD-FVT (Mid-Duty forged) | 6″-10″ forged steel | Tapered roller | 6,000 - 10,000 lb | R-MD-63FVT (6x3 rigid 10k lb) |
| EPSD-FVT (Extra-Heavy) | 8″-12″ forged steel | Tapered roller | 8,000 - 10,000+ lb | R-EPSD-83FVT (8x3 rigid 10k lb) |
| STL-SVB (Stainless V-Grooved) | 3″-6″ stainless | Sealed bearing | 325 - 1,200 lb | R-STL-3SVB (3″ stainless 325 lb) |
| CH-VT (Cast V-grooved tapered) | 4″-8″ cast iron | Tapered roller | 1,000 - 3,000 lb | R-CH-6VT (6x2-3/4 cast 3,000 lb) |
A flat-tread caster on a flat rail relies on the rail edges to keep the wheel centered — under any lateral load (a cart bumping into the rail, an off-center load pushing sideways), the wheel walks toward the rail edge and eventually falls off. V-grooved wheels solve this by inverting the geometry: the rail itself is an inverted V (peaked steel bar welded or anchored to the floor), and the wheel’s V-shaped groove rides on top of it. Gravity, plus the angled contact surfaces, automatically pull the wheel back to centered whenever it shifts sideways. The result: a cart loaded to the wheel’s rated capacity rolls straight down the track at 3 mph (Hamilton’s published rolling speed for the EPSD-104FVT 10,000 lb caster) without operator correction.
The trade-off is that V-grooved wheels only work on V-rail track — you can’t roll them on standard floors (the V-groove rides on the floor edge and causes wear). For applications that need to leave the track and roll on standard concrete, see Hamilton’s F (flanged) wheel series instead, which has a flanged side that can ride on flat floors when needed.
The standard inverted-V rail is 1-3/8″ or 1-3/4″ wide at the base with a 60° included angle (each side of the V at 30° from vertical). Hamilton’s W-V Series wheel grooves match this profile. For non-standard V-rail (some custom factory installations use 90° included angle V), the wheel groove geometry differs — email info@casterhq.com with the rail cross-section dimensions for a match.
Briefly, yes — for crossing aisles or moving the cart off the track for maintenance. The V-groove rides on the floor at two narrow contact points which transfers load to a small area and accelerates floor wear. For continuous on-and-off-track operation, specify Hamilton’s F (flanged) series wheels instead — these have a flanged outer rim that rides on flat floors when off-track.
The Hamilton EPSD-104FVT (10″ x 4″ forged steel V-grooved swivel) at 10,000 lb per caster — with the 1-1/4″ precision tapered roller bearing rated for 3 mph rolling speed. For 4-caster cart configurations: 40,000 lb static cart capacity. Caster Concepts manufactures heavier V-grooved variants reaching 16,000 lb per caster for steel mill and aerospace applications — available on special order via CasterHQ.
Yes — the Hamilton R-STL-3SVB and STL-SVB stainless variants are stocked for food processing, pharma, and washdown V-track applications. Capacity range 325-1,200 lb per caster on stainless construction. NSF documentation available for the stainless line at info@casterhq.com.
Both. The W-V wheel-only variants ship without a yoke for installing into existing OEM caster yokes. The swivel (S-prefix) and rigid (R-prefix) variants ship as complete casters with top plates — typically the 4″ x 4-1/2″ medium-heavy industrial plate, with larger 4-1/2″ x 6-1/4″ and 6-1/2″ x 7-1/2″ plates on the heaviest FVT variants. Verify your existing equipment plate before ordering.
Hamilton is the dominant V-grooved manufacturer; cross-reference is supported when you bring a Hamilton W-V or FVT part number. For competitor V-grooved (Caster Concepts, Albion track wheels, Faultless), email info@casterhq.com with the existing part for a Hamilton-equivalent match. Stock casters ship same day from Mansfield, TX before 3 pm Central. Heavier FVT variants ship LTL freight on fleet quantities.
