Lubricating your crossbow properly is essential to keep it in top working condition. A well-lubricated crossbow will be smoother, quieter, and easier to cock and fire. It will also have a longer lifespan. This blog post provides a step-by-step guide on how to lubricate a crossbow correctly using common household lubricants.
Overview of Crossbow Lubrication
| Steps | Lubricants Used |
| 1. Clean the crossbow | Rubbing alcohol |
| 2. Lubricate the rail | Lithium grease or wax-based lubricant |
| 3. Lubricate the string | String wax or lubricant |
| 4. Lubricate the cams/wheels | Light oil or lubricant |
| 5. Lubricate the trigger mechanism | Light oil or lubricant |
Step-by-Step Instructions
1. Clean the crossbow
The first step is to clean your crossbow thoroughly before lubricating. This removes any built-up dirt, dust or debris that could hinder performance.
- Use a soft, lint-free cloth to wipe down all accessible surfaces of the crossbow. Rubbing alcohol works well for this task.
- Pay close attention to the rail, string, cams/wheels and trigger mechanism. These areas need to be spotless.
- Allow the crossbow to fully dry before moving onto lubrication.
2. Lubricate the rail
The rail is one of the most important parts of the crossbow to keep lubricated. This allows the arrow to glide smoothly along the rail when fired.
- Use a lithium grease or a wax-based lubricant made specifically for crossbow rails. Do not use regular grease or oil.
- Apply a thin layer along the entire length of the rail using the lubricant applicator or a soft cloth.
- For wax lubricants, rub the wax stick back and forth along the rail to evenly coat it.
- Wipe away any excess lubricant and let it dry before cocking or firing the crossbow.
3. Lubricate the string
Keeping the string lubricated prevents fraying and increases speed and power.
- Use a string wax or lubricant made specifically for crossbow strings. Regular wax or oil will damage the string over time.
- Hold the wax stick or lubricant applicator perpendicular to the string to apply an even coat. Move slowly back and forth along the entire length of the string.
- Rub the wax or lubricant into the strands of the string using your fingers to evenly distribute it. This helps the lubricant penetrate better.
- Remove any excess lubricant with a soft, dry cloth. Let the string dry completely.
4. Lubricate the cams/wheels
The cams or wheels on a crossbow receive a lot of friction, so keeping them lubricated is critical.
- Use a light oil or lubricant designed for crossbow wheels and axles. Make sure it does not contain any solvents that could damage plastic parts.
- Apply 2-3 small drops directly onto each wheel, cam and axle.
- Rotate the wheels and cycle the crossbow slowly to evenly distribute the lubricant.
- Wipe away any excess. Allow the lubricant to soak in before cocking and firing.
5. Lubricate the trigger mechanism
It’s important to lubricate the trigger mechanism so the crossbow fires smoothly and reliably.
- Use a very light oil or lubricant made for crossbow triggers and sears. You only need a small amount.
- Apply 1-2 drops onto the trigger sear surfaces where metal contacts metal when cocked.
- DO NOT over-lubricate the trigger. This can cause unintended firing.
- Cycle the safety and trigger a few times to distribute the lubricant. Wipe away any excess.
6 Lubrication Tips
Follow these additional tips for safely lubricating your crossbow:
- Always follow the manufacturer’s lubrication instructions for your specific model.
- Apply lubricants sparingly. More is not better. Too much can attract dirt and debris.
- Reapply lubricant every 10-20 shots or as needed. Check the rail after each shot.
- Do not get lubricants on the bowstring serving or on the arrows. This can greatly impact accuracy.
- Use lubricants specifically designed for crossbows. Hardware store varieties can damage parts.
Frequently Asked Questions
How often should I lubricate my crossbow?
Most crossbows should be lubricated every 10-20 shots at a minimum. The rail may need lubricating more frequently. Inspect wear and reapply lubricant after every trip.
What lubricants should not be used on a crossbow?
Avoid WD-40, 3-in-1 oil, grease, and other multi-purpose lubricants. Stick with lubricants designed specifically for crossbows.
Where can I buy crossbow lubricants?
Specialty crossbow lubricants are available at most major sporting goods stores or online at retailers that sell archery equipment. Look for wax sticks, lubricating grease, string wax and light oils.
How do I lubricate crossbow string loops?
Apply string wax or lubricant lightly over the entire length of the loop. Rub it into the threads with your fingers to evenly distribute it. Avoid over-saturating the serving.
Can I use too much lubricant on my crossbow?
Yes, using excessive lubricant can attract dirt and debris that will hamper performance. It could also damage the bow if dripped onto the limbs. Apply lubricant sparingly.
How do I lubricate plastic bushings and pulleys?
Use a tiny amount of light oil or plastic-safe lubricant on anything plastic. Let it soak in. Do not use grease or heavy lubricants that could damage plastics.
