Product type: Adjustable stainless steel carriage rollers for sliding doors
Wheel structure: Stainless steel wheels mounted in a stainless steel carriage with a height-adjustment screw. Bearing options include high carbon steel, bearing steel, stainless steel and customized specifications. Outer material options include nylon, POM, stainless steel and customized materials.
These carriage rollers are designed for sliding door systems that require stainless steel wheels, a rigid metal carriage and stable load support. The recessed structure fits inside compatible aluminum and uPVC door profiles, while the adjustment screw allows the roller height to be changed and the door to be aligned after installation.
Single-wheel and multi-wheel configurations are available for different door sizes and working loads. Wheel diameter, wheel width, flat, concave or grooved profile, bearing type, stainless steel grade and carriage dimensions can be customized according to a drawing, sample or door profile. No numerical load rating is stated in the supplied page.
Product Applications
Adjustable stainless steel carriage rollers are suitable for sliding door and window systems where metal wheels and height adjustment are required. Typical applications include:
Aluminum sliding doors: the recessed carriage fits inside a compatible aluminum bottom profile and the adjustment screw sets the door height.
uPVC sliding doors: the stainless steel carriage can be reviewed for compatible uPVC door profiles and track dimensions.
Heavy patio and balcony doors: multi-wheel configurations can distribute the working load across several contact points.
Commercial sliding entrances: the metal carriage is intended for repeated door movement where the track and load conditions are suitable.
Sliding windows: the adjustable roller can be matched to compatible lower rails and window profiles.
Interior partition doors: the carriage provides guided movement and height adjustment for larger sliding panels.
Humid indoor environments: stainless steel components can be selected where better corrosion resistance than untreated carbon steel is required.
Custom door and window systems: wheel profile, carriage dimensions, adjustment range and bearing type can be customized.
