Stainless steel slave guiding rail ST53RS-BP53RS with BP53RS runners
ST53RS-BP53RS
The ST53RS-BP53RS guiding system combines a stainless steel ST53RS slave rail with BP53RS roller runners, to provide reliable, quiet and durable guiding in demanding, corrosive environments.
The ST53RS rail, available up to 2000 mm as standard, is designed to work alongside the ST53 rail. Its role as a slave rail significantly increases the overall tolerance of the assembly, by absorbing alignment, parallelism or flatness defects.
This design makes it easier to integrate the system into complex or less permissive mechanical structures.
The BP53RS runners contain plastic rollers. They ensure smooth, quiet operation while allowing higher operating speeds.

Applications
Combined with the ST53 rail, it provides greater mounting tolerances (alignment deviations, parallelism/flatness defects) and simplifies integration into constrained mechanical structures.
Quiet guiding, high mounting tolerances, ideal for corrosive environments. Can be used in applications in the nuclear sector.
This linear rail is designed for medium loads in applications requiring a very compact footprint, such as small covers or housings for protection on machinery.
The load is the maximum force that can be supported per runner. This type of product does not tolerate well loads that subject it to torque. As far as possible, the load should therefore be centred, or a second runner used to cancel out this torque.
Please refer to the technical data sheets for exact values.
The maximum speed for linear rails is 0.5 m/s.
Recommended operating temperatures from -20°C to 80°C.
Manufacturing
The ST53RS guiding system is manufactured from rigorously selected materials to guarantee excellent mechanical performance and lasting resistance to aggressive environments.
The ST53RS rail is made of stainless steel, then machined with great precision to ensure consistent geometry along its full length. It is available up to 2000 mm as standard and benefits from tightly controlled dimensional tolerances, essential to its role as a slave rail. This design absorbs alignment and mounting defects while maintaining smooth, reliable operation over time.
The BS53RS and BP53RS roller runners are assembled with robust mechanical components, specifically chosen for their resistance to wear and corrosion. The rollers ensure controlled contact with the rail, limit friction and contribute to quiet operation, even at high operating speeds.
The BS53RS runner’s bearings are made of stainless steel, while the BP53RS runner’s are made of plastic.
The entire system undergoes quality control at every manufacturing stage, guaranteeing repeatable performance and reliable guiding under severe industrial conditions. This manufacturing standard allows ST53RS systems to durably meet the demands of applications exposed to humidity, corrosive agents and repeated mechanical stress.
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.
