This part is a steel ball-bearing sliding window roller assembly used in a horizontal sliding aluminum window. The roller features a concave (grooved) steel wheel designed to ride on a raised aluminum track inside the window frame. The wheel rotates on sealed ball bearings to support the weight of the sliding sash and allow smooth operation.
The roller is housed in a compact metal carriage that installs into the bottom rail of the window sash and typically includes an adjustment slot or screw for height alignment.

Hello,
Thanks for writing in! The only roller wheel that matches your description is the 87-089 Replacement Brass Wheel & SS Axle. To determine if this is the correct replacement match, carefully look over the dimensions below.
I'm happy to take a look and see if we might have the entire roller. I'll just need to see a photo of the existing housing.
