304L stainless steel linear rail STV18-BSV18R3 with 3-roller runner
STV18-BSV18R3
The STV18-BSV18R3 guiding system combines an STV18 rail with a BSV18R3 roller runner to provide a compact, reliable and durable guiding solution for demanding industrial environments.
Made entirely of 304L stainless steel, it is particularly well suited to humid, corrosive environments or those subject to frequent washdowns.

Applications
This compact linear rail is designed for applications requiring a very small footprint.
Its specific geometry limits particle retention and facilitates the evacuation of impurities, contributing to reliable operation in fouling environments.
It is particularly suited to applications requiring precise, compact and fast guiding, with high operating speeds, including in repeated cycles.
Recommended operating temperatures from -20°C to 80°C.
This compact rail was specifically designed for the aerospace industry but is also often used in the food processing sector.
It offers several advantages:
– ultra-compact
– significantly lightened, meeting decarbonisation challenges
– several runner lengths available (BSV18R3 | BSV18R5)
– flat mounting possible with a maximum load of 100 kg per runner
The STV18 rail can be manufactured in a curved version. Contact us for more information.
Manufacturing
The STV18 rail, of prismatic shape, is made of cold-drawn 304L stainless steel and available up to 2000 mm in standard length.
Its specific geometry limits particle retention and facilitates the evacuation of impurities, contributing to reliable operation in fouling environments.
The BSV18R3 runner, fitted with 3 stainless steel rollers mounted on a stainless steel plate, ensures quiet, smooth guiding.
As standard, rails are supplied undrilled.
Maintenance
The rails are factory-lubricated with a high-pressure bearing grease for optimal service life.
In the case of special conditions (abrasiveness, high cycle rates), regular and systematic maintenance should nonetheless be planned.
The runners must be greased regularly.
Options
Runner options
– Choice of several lengths (BSV18R3: 3 rollers | BSV18R5: 5 rollers)
Temperature
For use above 80°C (HT), please contact us
Modification of the standard
For specific projects or particular integrations, the EV18 rail can be supplied curved on request, subject to a defined order volume.
