We have most of the bearings used in popular reels in stock as either chrome steel or stainless steel. Unfortunately, some manufacturers, such as Shimano, give a different part number for the same bearing depending on which reel it goes in.
It is difficult for a small shop like ours to keep up with all the different bearing part numbers so we have a search feature just for that. All you have to do is use the ID - OD - TH search to find the bearings you need. Nearly all bearings used in reels are metric and the ID and OD are whole millimeter measurements. This means if your calipers show 5.96mm, it is a 6mm bearing.
When using the search, you only need to select ID and OD and hit search. The thickness is extra and not necessary to find bearings in our store.
As always, if you are having trouble finding the bearings you need, give us a call!
