How To Grease Bike Crank Bearings? [5 Easy Steps]

It’s important to keep your bike in good working order, and that includes regularly greasing the crank bearings. This task is relatively simple and only takes a few minutes to complete. In this article, I will want to show you how to grease bike crank bearings in 5 easy steps.

What Are Bearings On A Bike?

A bearing is a device that allows two surfaces to move smoothly past each other with reduced friction. Bearings are often found in wheels and other rotating parts.

Bike bearings are usually made of steel and are found in the hubs, bottom brackets, and headsets. When bearings wear out, they can cause friction and resistance in the spinning parts of the bike, making it harder to pedal.

Bearing maintenance is important to keep your bike running smoothly. Bearings should be cleaned and lubricated regularly to prevent wear and tear. If you notice any resistance in your bike’s spinning parts, it’s a good idea to check the bearings and make sure they are in good condition.

Where Do I Grease My Crankset?

Assuming you’re referring to a bicycle crankset, there are a few key places where you should apply grease. First, you’ll want to grease the inside of the crank arms where they attach to the spindle. You’ll also want to grease the threads on the spindle itself. Finally, you’ll want to apply grease to the pedal threads.

When greasing the inside of the crank arms, it’s important to get a good amount of grease into the interface between the arm and the spindle. This will help to reduce friction and prevent the arms from creaking.

The same goes for the threads on the spindle – you’ll want to make sure they’re well-lubricated to reduce friction.

As for the pedal threads, it’s important to apply grease to both the inside and outside of the threads. This will help to keep the pedals from coming loose and make it easier to thread them back on if they do come loose.

In general, it’s a good idea to apply grease to any moving parts on your bicycle. This will help to keep them running smoothly and prevent any premature wear.

What Grease Should I Use To Grease Bike Crank Bearings

Lithium grease is a versatile, all-purpose grease that can be used for a variety of applications, including bike crank bearings. This type of grease is made from a mixture of lithium soap and mineral oil, and it has a number of benefits that make it ideal for use on bike bearings.

Lithium grease is designed to withstand high temperatures and heavy loads, making it ideal for use on bearings that are subject to a lot of stress. The grease is also resistant to water, which means it will not wash away easily in the rain or during a ride.

Lithium grease is also relatively easy to find and relatively inexpensive, making it a good option for those on a budget.

How To Grease Bike Crank Bearings?

It’s important to keep your bike in good working order, and that includes regularly greasing the crank bearings. Here’s a step-by-step guide on how to do it.

You’ll need:

  • A bike stand
  • Grease
  • A rag or paper towel

Here are 5 easy steps to grease bike crank bearings:

  1. Step 1: Put the bike in a bike stand. This will make it easier to work on.
  2. Step 2: Remove the crankarm. There should be a bolt holding it in place. Use a wrench to loosen it and then remove the arm.
  3. Step 3: Clean the spindle, bottom bracket bearings, crankarm, and bolt. Use a rag or paper towel to wipe away any dirt or grime.
  4. Step 4: Add a good level of grease to the spindle and bottom bracket bearings. Use your fingers to work it in.
  5. Step 5: Reinstall the crankarm. Line up the bolt holes and then tighten the bolt.

That’s it! You’ve now successfully greased the bike crank bearings.

How Often Do You Need To Grease The Crank?

A good rule of thumb is to grease the crank every 12 months. This will help to keep it from getting too dry and cracking, and will also help to protect it from the elements.

If you live in an area with lots of rain or snow, you may need to grease the crank more often. And if you ride your bike frequently, you may also want to consider doing it more often.

Ultimately, it’s up to you to decide how often to grease the crank. But following the 12-month rule is a good place to start.

Should You Grease Bike Crank?

Yes, you should grease them. But there is no real need to do it yourself unless you’re planning on doing a lot of riding in wet or muddy conditions.

Bike cranks usually come with bearings that are already greased. But if you’re going to be doing a lot of riding in wet or muddy conditions, it’s a good idea to give them a fresh coat of grease. This will help keep the bearings from rusting and will also make pedaling easier.

If you do decide to grease the bearings yourself, it’s important to use good-quality grease. You don’t want to use something that’s going to break down quickly or that will attract dirt and grime. Good quality grease will help keep your bearings lasting longer.


In conclusion, if you follow these easy steps you shouldn’t have any problems greasing your bike’s crank bearings. By taking the time to do this simple maintenance, you can extend the life of your bike and keep it running smoothly for years to come.
