sliding window rollers Yale Ogron

Thanks for reaching out! I'm afraid we may not have a sliding window roller we can recommend to replace your Yale Ogron roller but I'm happy to take a look into this for you. 

May I see a photo of the where and how this roller installs to the bottom of the window sash? Please also confirm the diameter of the pin in the roller as well as the diameter of the wheel.

Please don't hesitate to reach out with any questions you might have.
