How to measure your bearings of baitcasting reel?


If you want a bait finesse special which emphasizes lightweight and response, using Roro SIC Bearings is your best choice.

Baitcaster - and especially BFS fans - can get an instant performance boost with the ultra high quality Roro bearings. It can be difficult to know exactly which size and specification to get though. How to identify the size of bearings? You just need to prepare a calipers.

There are three data of bearing, we want to know:

  • Outside diameter (OD)
  • Inside diameter (ID)
  • Width (W)

For the bearings, we normally call it with these three data.

Example, if outside diameter = 10 mm, Inside diameter = 3 mm, Width = 4mm

this bearing was named as 1034 or 3 x 10 x 4 mm.

In many cases you'll be able to double-check on the Roro bearings site that the bearings and your reel model match.
