Sliding window roller

As you can see they are in disrepair and needing replaced (the roller falls right out). Can you help me find replacement roller please? They are 1 3/4 inch long, 3/8 inch wide. Not sure how wide they are at the widest point in the assembly where it wedges into the frame. Thank you so much for your help!

I am afraid we might not have an exact match for this window roller. Dimensions for replacements must be exact to have any shot of working. Our best bet I think would be the 87-061. Compare the dimensions with an undamaged roller and see what you think.

These sliding window rollers can be very tricky to replace. Whoever supplied the window would be the best bet, though even then not a sure thing. Otherwise, a local hardware store that has experience with houses and windows in your area might happen to carry spares. It's a crapshoot, I'm sorry to say. Apologies we can't do more, and good luck with the search.
