Where do you apply grease in the fishing reel?

Reel grease is mainly used in a fishing reel where components are heavily loaded or operate under pressure. Due to its viscous consistency, grease stays in place longer and reliably protects the mechanism from wear.

Unlike Reel oil, grease is especially suitable for gears, gearboxes, and mechanical components under higher loads.

Typical application areas for Reel grease

Main gearbox

The main gearbox is one of the most important areas for Reel grease. Here, gears mesh and transmit power when cranking.

  • reduces gear wear
  • ensures smooth and even operation
  • protects the gearbox in the long term

For very light reels or BFS setups, softer greases are often used, while for larger reels, a more stable grease is advisable.

Gears and drive parts

Other gears and mechanical drive parts also benefit from Reel grease. The lubrication ensures that the gears mesh cleanly and do not wear unnecessarily.

  • reduces mechanical friction
  • extends the lifespan of the components
  • ensures even power transmission

Wormshaft / Levelwind System

The Wormshaft moves the line guide and is lubricated differently depending on the reel size.

  • for medium and larger reels, grease is often used
  • for very light reels, oil can also be used

Grease provides durable lubrication here and protects the mechanism under higher loads.

Brake system

Some Reel greases are specially developed for brake systems (Drag Systems).

This grease ensures that:

  • the brake operates evenly
  • no jerky braking movements occur
  • the brake discs are protected

Important: For brake systems, a suitable Drag Grease should always be used, as not every grease is suitable for this area.

Heavily loaded mechanisms

Other mechanical parts of a fishing reel also benefit from Reel grease, especially when they operate under pressure.

These include, for example:

  • mechanical levers
  • drive components
  • heavily loaded moving parts

Here, grease ensures stable lubrication and prevents unnecessary wear.

Where should Reel grease not be used?

For fast-rotating components, Reel grease is generally not suitable. Instead, Reel oil is used in these areas.

Typical examples:

  • Spool bearings
  • Line roller bearings
  • Spool ball bearings

Here, grease would slow down the rotation and impair the reel's performance.

Exception: Greased ball bearings

In some cases, ball bearings can be deliberately greased. Especially stainless steel ball bearings or bearings from the heavy-duty range are often greased from the factory.

This has several advantages:

  • better protection against corrosion
  • longer lubrication effect
  • higher load capacity under pressure

Such bearings are often used where reliability and durability are more important than maximum speed.

In baitcaster tuning, spool bearings are often deliberately operated with thin reel oil to achieve the smoothest possible spool rotation.

Pro tip – seal screws and housing

A small but very effective trick in reel maintenance is to lightly coat housing screws with reel grease.

This has several advantages:

  • Screws can be loosened much more easily during the next maintenance
  • Saltwater and moisture have a harder time penetrating the threads
  • Dirt and deposits adhere less firmly

Especially when used in saltwater, this small step can help prevent corrosion and make reel maintenance easier in the long run.

Many anglers also refer to this as "sealing the reel". Grease is applied specifically to spots where dirt or water could enter the reel.

Typical sealing points

Many tuners lightly grease the following areas to make it harder for saltwater and dirt to penetrate:

  • Side plate sealing surfaces
  • Frame transitions
  • Levelwind cap threads
  • Housing screws

These areas are considered typical entry points for water and dirt. A thin layer of grease can act as an additional protective barrier here.

When grease is placed at the right entry points, saltwater, moisture, and dirt have a much harder time getting inside the reel.

Tip from practice

For reel grease, the rule is: A thin layer is completely sufficient.

Too much grease can unnecessarily make the mechanics stiff. An evenly distributed, thin layer provides optimal protection and smooth operation of the reel.
