Double nylon roller for replacement sliding-door hardware
This double nylon sliding door roller is the nylon-wheel configuration of the adjustable trolley series. Two bearing-equipped grooved wheels are installed in a stainless steel housing. It is intended for distributors, repair-hardware buyers and profile-system projects that specify nylon wheels and need to match an existing roller assembly.
Use it in aluminium or uPVC running systems only after checking the original profile and track. For glazed sliding panels, the trolley interfaces with the frame or profile; compatibility must be reviewed for that assembly. The photograph illustrates the trolley layout; wheel material follows the selected configuration.

Material and order confirmation
Nylon and POM are separate material options. If replacing a specified nylon roller, keep the polymer grade, bearing interface and groove geometry in the approval record. Stainless steel housing grade and bearing steel grade are separate selections; confirm both for the installation environment.
Free samples are available for fit review. Confirm sample scope and shipping arrangements, followed by order quantity, packing, carton quantity, delivery terms and required dispatch schedule in the quotation.
Procurement FAQ
Can this nylon roller replace an existing aluminium door trolley?
Compare the full housing length, width and height, fixing points, adjustment access, wheel groove and track profile. A matching nominal size alone does not establish interchangeability. Send the original trolley photos and measurements.
Can this roller be used in a uPVC or glazed sliding door?
It can be considered for compatible uPVC or glazed sliding systems after checking the profile pocket, rail and panel requirements. It is not a universal fitting or a glass-clamping roller.
What should I specify for the nylon wheels and bearing?
State the nylon grade requirement, wheel dimensions, U-groove geometry, bearing code, shielding or sealing and operating environment. Confirm these items in the quotation and approved sample.
Is USD 0.25 the price for a pair?
The displayed price is USD 0.25 per piece, based on one trolley assembly. The photo shows two assemblies for reference. Quantity, packaging, delivery terms and the selected configuration are confirmed in the quotation.
Compare sliding-door roller options
If your specification calls for POM rather than nylon, review the adjustable POM sliding door trolley 13×20. Confirm the material and full installation dimensions before selecting either configuration.
Browse the sliding door pulley and trolley range for other bearing and housing arrangements.
Check dimensions, track fit and load-rating units
Before choosing a trolley, use our sliding door trolley roller selection guide to compare housing dimensions, U-groove and rail fit, POM or nylon specifications, bearing details and load-rating units.
