Mid-to-high-end Quality Sliding Window Roller For Aluminum Sliding Window And Door Accessories Hardware Nylon Wheel Nylon Housing Iron Inner Housing Load Capacity 100KG

• Component Breakdown (Decoding the Description)

  1. "For Aluminum Sliding Window and Door Accessories Hardware":

     • Application: Specifically designed for the channels (tracks) of aluminum sliding systems, which have standard profile dimensions.

     • Role: It's a critical "accessory" or "hardware" component that ensures the moving sash (the part of the window that slides) glides effortlessly.

  2. "Nylon Wheel":

     • This is the outer part of the roller that makes direct contact with the aluminum track.

     • Benefits of Nylon:

       • Smooth & Quiet: Provides a much quieter operation than all-metal wheels.

       • Wear-Resistant: Resists abrasion from the track, extending its life.

       • Non-Marring: Will not scratch or wear down the aluminum track.

       • Self-Lubricating: Often has low-friction properties, reducing the need for frequent maintenance.

  3. "Nylon Housing":

     • This is the main structural body or frame that holds the wheel and inner housing. It's the part typically screwed into the bottom corner of the window sash.

     • Benefits:

       • Corrosion Proof: Impervious to rust, a critical feature for hardware exposed to weather.

       • Lightweight & Strong: Offers excellent structural integrity without adding weight.

       • Dimensional Stability: Maintains its shape and size through temperature changes.

  4. "Iron Inner Housing" (or more accurately, "Steel Inner Bearing Housing"):

     • This refers to the inner sleeve or bushing that the axle (a steel pin) passes through. It's the core that the wheel rotates around.

     • Why Iron/Steel is Used Here:

       • High Load-Bearing Strength: The steel core handles the compressive force of the window's weight, preventing the nylon from deforming over time.

       • Precision Bearing Surface: Provides a smooth, hard surface for rotation. In higher-end versions, this may even be a sealed ball bearing unit for ultra-smooth rolling.

  Why This Combination = Mid-to-High-End Quality

  • Material Synergy: It combines the best properties of both materials:

    • Nylon for quiet operation, track protection, and corrosion resistance.

    • Steel/Iron for structural strength and load capacity.

  • Durability: This design is far superior to all-plastic wheels (which can crack under heavy loads) or all-metal wheels (which are noisy and can wear the track).

  • Performance: Ensures smooth, consistent sliding action for years, even with large or heavy insulated glass panels.

  • Weather Resistance: The nylon components won't rust or corrode in humid or coastal environments.

  Key Specifications to Check When Ordering

  To ensure a perfect replacement, you need to match:

  1. Wheel Diameter & Width: Measured in millimeters (e.g., 28mm x 16mm). Must fit the existing track channel.

  2. Mounting Type & Screw Hole Pattern: How the roller is attached to the window sash (e.g., side-mount, bottom-mount, center distance between screws).

  3. Overall Height (Adjustable vs. Fixed): Many mid-to-high-end rollers have a height-adjustment screw. This is a crucial feature for aligning the window, compensating for settling, and ensuring the sash is lifted just off the track for smooth rolling.

  4. Load Rating: The weight capacity per roller. High-quality rollers will have a specified rating (e.g., 50kg per wheel).

1. Remove your old roller wheel from the window frame
2. Measure the outer diameter of the old wheel
3. Measure the width (thickness) of the old wheel
4. Measure the diameter of the center axle pin hole
5. Confirm measurements match our 25mm (OD) × 20mm (W) size
