McLube OneDrop: The Ball Bearing Lubricant your Balls are asking for

McLube is helping make sailboat maintenance one step closer to being considered “no big deal” with the McLube OneDrop Ball Bearing Conditioner. I know what you’re thinking, why on earth would I want conditioner for my ball bearing blocks and traveler cars? This isn’t like the Herbal Essence you have in your shower at home though – McLube designed this to specifically lubricate and clean the ball bearings in your traveler cars or battcars.

So why do you need OneDrop if you already have a marine lubricant that works just fine?

Most everyone knows about¬†McLube’s main lubricant product in the sailing market,¬†SailKote, which most simply refer to as McLube. It’s great stuff and definitely helps the outhaul on my Laser slide better, mainsails slide up mast tracks more smoothly and all sorts of other useful things. What you might not know is that its not a great idea to use on your traveler cars or blocks.


SailKote will eventually eat away at the plastic in blocks, causing them to perform worse over time rather than better, even if their short term performance improves. Particuarly in regards to traveler cars – if you spray them with SailKote you can actually make the too smooth. Basically SailKote will reduce the friction so much that the ball bearings in the car won’t spin and over time that causes flat spots on the balls where they’ve been hitting the track. Once that happens no amount of SailKote is going to make the car run smoothly.

This is where OneDrop comes in – use it on your traveler cars and battcars instead of SailKote and you will prolong the life of your hardware and help your cars run more smoothly.

How do you use it?

You’ll want to clean off the car and the bearings first. On the package it’s suggest you could just squirt soapy water into the car and run it back and forth on the track but it’s really going to be better to remove the car from the track and even to remove the ball bearings and clean them separately. At least at the start of the season it’s a great idea to take it all apart, inspect the bearings and replace any that aren’t up to par (have any flat spots or show excessive wear).

After cleaning the car you can reassemble it and apply a drop of the OneDrop, slide the car back and forth to coat all the bearings and than remove any excess. Depending on the size and condition of your car you may in fact need more than one drop, but I figure they just thought the name was catchy.

Check out McLube’s OneDrop when you’re getting your boat back into shape this season and want to make sure it stays that way all summer long.
