Treadmills handle daily workouts with ease but like any machine with moving parts, they require regular maintenance. One of the most important and often overlooked, tasks is lubricating the treadmill belt.

When done correctly, lubrication helps the belt move smoothly, reduces strain on the motor, and prevents premature wear. This guide explains how to lube a treadmill safely, how often it should be done, and what to avoid.

Why Treadmill Lubrication Matters

Every time you step on a treadmill, the belt presses against the deck underneath. This creates friction. Over time, that friction forces the motor, rollers, and belt to work harder than necessary.

Lubrication creates a thin protective layer between the belt and deck. This reduces resistance, keeps the belt moving evenly, and helps the motor maintain consistent speed. A properly lubricated treadmill also runs quieter and feels smoother underfoot.

Skipping this simple task is one of the main reasons treadmills wear out prematurely, often leading to costly repairs.

How Often Should You Lube a Treadmill

Most treadmills need lubrication every three months or after about 40 to 150 hours of use. The exact timing depends on your model, belt type, body weight of users, and how frequently the treadmill is used.

Signs that lubrication may be needed sooner include

• A dry or rough feeling under the belt
• Squeaking, rubbing, or unusual noises
• Belt hesitation, skipping or uneven movement
• A maintenance reminder displayed on the treadmill

Always check your owner’s manual first. Some treadmills use self-lubricating or wax-coated decks and should not be lubricated manually.

How to Tell If Your Treadmill Needs Lubrication

Simple hand check you can do at home

Turn the treadmill off and unplug it. Carefully lift one side of the belt and slide your hand between the belt and the deck near the center.

If the surface feels slightly slick, lubrication is still present. If it feels dry, chalky, or warm, it is time to lubricate.

Do not rely only on the edges of the belt. The center area experiences the most friction and often dries out first.

What Type of Lubricant Should You Use

Why silicone lubricant is recommended

Most manufacturers recommend 100 percent silicone lubricant made specifically for treadmills. Silicone reduces friction without damaging the belt or deck materials.

Products you should never use

Avoid using

• WD-40
• Petroleum-based sprays
• Grease
• Household or cooking oils

These products can damage the belt material, attract dirt, and even void your warranty.

Things to Do Before Lubricating Your Treadmill

Before starting, make sure

• The treadmill is powered off and unplugged
• The area around the treadmill is protected from drips
• You have a clean cloth ready
• Make sure you know if your belt needs loosening, and have an Allen key ready if it does.

How to Lube a Treadmill Step by Step:

Turn Off and Unplug the Treadmill

Safety comes first. Always disconnect the power before placing your hands near the belt or deck.

Lift or Loosen the Belt

Gently lift one side of the belt. If it feels too tight, loosen the rear roller bolts slightly using an Allen key. Only loosen enough to slide your hand underneath.

Apply the lubricant correctly

Apply a small amount of silicone lubricant under the belt near the center of the deck. Focus on the area where your feet normally land. About half an ounce per side is usually enough.

Do not apply lubricant to the top of the belt.

Run the treadmill to spread the lubricant

Plug the treadmill back in and run it at a slow walking speed for three to five minutes. This helps distribute the lubricant evenly across the deck.

Afterward, wipe away any excess lubricant from the sides or frame.

Common Mistakes That Shorten Treadmill Life

Common mistakes include using the wrong lubricant, applying too much, lubricating a treadmill that doesn’t need it, forgetting to unplug or skipping regular maintenance checks.

Do All Treadmills Need Lubrication

No. Some newer or higher-end treadmills use maintenance-free decks or belts. Others display a reminder message when lubrication is required.

Lubricating a treadmill that doesn’t require it can cause slipping or mechanical issues. Always confirm the manufacturer’s recommendations before applying lubricant.
