🎣 How to find the right ball bearings for your reel – The ultimate guide for anglers

Introduction

Ball bearings are the heart of your fishing reel – without them, nothing runs smoothly. If you want to tune or maintain your reel, you should know which ball bearings fit, what types exist, and how to easily determine the right size yourself.
Here we show you step by step how to make the perfect choice and get your reel running as smooth as butter again. 🚀

What do the ball bearing sizes mean?

The ball bearing size is always specified in the following format: Inner diameter × Outer diameter × Width

Example:
A bearing labeled 3×10×4 means:

• Inner diameter: 3 mm
• Outer diameter: 10 mm
• Width: 4 mm

How do you measure the ball bearing size yourself?

You need:

• A caliper (digital or analog)
• A little patience

Here's how to proceed:

1. Remove ball bearings (often secured by a small clip in baitcasters – be careful!). 
   
2. Measure inside: Use the caliper to measure the inner diameter
    determine.
3. Measure outside: Measure the total outer diameter.
4. Measure width: Measure the ball bearing from the side..

When should you replace ball bearings?

There are two main reasons:

Wear:

• Reel runs rough or jerky
• Reduced casting distance
• Bearings squeak or feel "gritty"

Performance upgrade:

• You want longer casts
• You want a faster, more sensitive reel

⚠️ Attention:
Especially with older reels or after intensive use in saltwater, replacing the bearings can bring noticeable improvements!

Which spool bearings should you replace?

When it comes to tuning your baitcaster for more performance, the spool bearings are the first point of contact.
These bearings directly influence how easily and quickly your spool spins – and thus, how far and sensitively you can cast.

But beware: Not every reel is constructed the same!
Depending on where the ball bearings are located on your reel, you need to start at different points.

Here is a detailed guide on how to quickly and easily find out which bearings you should replace:

Variant 1: There is a ball bearing on the spool

👉 When you take the spool out of the reel and see a ball bearing directly on the spool (usually at the axle end on the handle side or opposite), then it applies:

• Replace the ball bearing on the spool.
• Also replace the ball bearing in the side plate (that is, the cover opposite the handle).

Why?
Both bearings work together directly during casting, they hold the spool and determine how freely it can turn.
A new, high-quality bearing on the spool is useless if the bearing in the side plate is still old and stiff – that's why always replace both.

Variant 2: There is no ball bearing on the spool

👉 In some reel models, there is no bearing directly on the spool – the spool then runs on axle bearings.

In this case, you should:

• Replace the bearing in the side plate (opposite the handle)
  and
• Replace the bearing under the Spool Tension Cap (on the handle side, under the small cover that regulates the spool pressure).

Why?
Here, the two outer bearings take over the guidance and rotation of the reel. It also applies here: Only if both bearings run well, will you get the full potential out of your reel.

This is how you can quickly find out what type your reel has:

1. Open the side plate (depending on the model, either by a folding mechanism or a screw).
2. Carefully pull out the reel.
3. Check:

• Is there a bearing directly on the reel? → Option 1
• Is there none on the reel? → Option 2

💬 Small tip:
Sometimes the bearings are well hidden on the reel – especially in smaller BFS or tuning models. A quick, attentive look saves a lot of work later!

⚡ Important:
Whether option 1 or 2 – always renew both relevant bearings!
Only then will you achieve maximum performance in terms of casting distance, spool start-up, and fine lure feel.

Tip for professionals:
Especially with reels designed for ultra-light lures (BFS) or maximum distance, it makes a huge difference when both spool bearings are replaced with high-quality ones.
With "standard reels," you might not notice it immediately on the first few casts, but especially with longer casts or delicate fishing, you will love the difference!

The pin remover – your tool for easy bearing replacement

If there is a ball bearing on your baitcaster's reel, it is almost always secured by a small pin.
And this pin can be really stubborn! Without the right tool, you quickly risk damaging the reel or bending the pin.

🎣 This is where the pin remover comes into play!

What does the pin remover do?

• It allows for the safe and damage-free removal of the pin on the reel.
• You can easily remove the bearing and exchange it for a new one.
• Even inserting the pin later becomes child's play with the remover.

💡 Tip:
If there is a ball bearing on your reel, you almost always need a pin remover to work cleanly.
Save yourself the cursing, flying pins, and scratches – get the right tool right away!

💬 Small experience value:
Many reels have extremely tight-fitting pins – especially high-quality models or new reels. Without a pin remover, you quickly end up prying at the material unsightly. With the tool, it’s relaxed in just a few seconds.

Use our handy ball bearing quick search

In our quick selection for ball bearings, you can find many common reel models with the right spool bearing sizes at a glance.

🎯 Advantage:
No guessing, no wrong orders – just search, find, upgrade!

Important: There are more bearings in your fishing reel!

In addition to the spool bearings, there are more ball bearings:

• Wormshaft bearings (line lay)
• Pinion gear bearings (main shaft)
• Knoblager (handles)
• Level wind bearings

For complete upgrades, it's worth taking a look at all bearing positions!

Which ball bearings fit which casting weight?

💡 Tip:
The lighter the lure, the more important precise, smooth-running premium bearings are.

🎯 Note:
With heavy lures (big baits, etc.), a good stainless steel bearing is often sufficient, as the casting weight provides plenty of momentum.

⚠️ Important:
Premium bearings show their advantage especially with small, light lures – you can definitely feel the difference!

ABEC rating explained in simple terms

The ABEC rating evaluates the manufacturing accuracy of ball bearings.
The higher the number, the more precise the bearing – and the smoother the run.

🎯 Note:

• ABEC 5 is more than enough for everyday reels.
• ABEC 7 or 9 makes perfect sense for tuning and finesse.

Features of hybrid, ceramic, and stainless steel ball bearings

Hybrid and ceramic bearings:

• Can run with or without oil.
• Without oil: less friction, more noise.
• With oil: a bit more resistance, but quieter and more durable.

Covers:
Our hybrid bearings have small dust protection covers.
If you remove them:

• Advantage: Less friction, more speed.
• Disadvantage: Higher susceptibility to dirt.

Stainless steel bearings:

• Must always be oiled.
• For extreme loads (big bait, saltwater), light greasing is even recommended.
