Chain tensioner pulley B version 8mm

Chain tensioner roller, B version, 8 mm. This is the replaceable part of the tensioner: the roller wears down and starts to buzz or wobble, while the tensioner itself stays in working order.

• Dimensions from the maker's drawing: roller diameter Ø 36 mm, width 36 mm, centre diameter Ø 23 mm
• Bearing bore Ø 8 mm — that is what your tensioner bolt needs to be; the 8 mm given in the name means exactly this
• A sealed ball bearing inside — visible from the end in the photo
• A groove down the middle — the chain runs in it and does not jump sideways
• You will find tensioners, sliders and chains in the same list
• Supplier codes WI ZQL7006, ZQR7006 and ZQA7006 — quote them again when ordering

To be straight with you: what "B version" means in the name, the maker did not explain — it is their own internal marking for the versions, and we are asking them about it. Before ordering, measure your bolt's diameter and the roller's width — we will check it before you order.
