How it connects
Unfastened rolling contact interface; the female 90-degree circumferential groove of the wheel straddles and rolls along the male elevated inverted V-ridge under gravity or load.
Male and female halves
Male running ridge (the raised apex of the inverted V track) mates with a female matching circumferential V-groove in the rolling wheel.
Usually connects to
- V-groove wheel
- V-groove caster
- V-groove track roller bearing
Common sizes
- Formed from 1" to 2" angle iron or pressed plate (commonly 1-1/2" to 3-1/2" track base widths), mating wheels typically 2" to 6" in diameter with 7/8" to 1-1/2" groove widths.
Where it is used
sliding driveway and security gatesindustrial rolling cartsconveyor trackslinear motion guide systems
Variations
- inverted angle iron welded to base plate
- single-piece formed/galvanized sheet metal V-track
- precision ground linear V-guide rails (e.g., DualVee / Bishop-Wisecarver style)
How to recognise it
A continuous longitudinal rail featuring a prominent 90-degree pointed peak or apex running its length, flanked by flat mounting flanges or angle legs, upon which a grooved wheel rests.
Often confused with
| Confused with | How to tell them apart |
|---|---|
| U-groove / round track rail | V-track has a sharp or chamfered 90-degree peak profile, whereas U-track or round pipe track has a semicircular/cylindrical profile mating round-grooved wheels. |
| Y-groove track | Y-track typically incorporates a rounded top crest or stem, whereas standard 90° V-track uses planar angled flanks forming an inverted V. |

Good to know
Commonly fabricated either by inverting standard structural steel angle iron onto a flat bar/surface or from roll-formed/stamped galvanized sheet profile.
