Closet Bottom Roller 1-1/4 Inch (with Guide)

Hi there,

I'm looking for a replacement part for my sliding closet door. Ideally I'd like this exact same hardware, but based on my deep dive search online, maybe it isn't made anymore? If so, might you have any suggestions for what i could use as an alternative replacement part?

See photos attached for reference, but the current roller is 1-1/4 inches with a ball bearing concave wheel (1/4 inch width) with a track guider.

Any help would be greatly appreciated! Thanks in advance :)
