If you’re serious about keeping your skate bearings fast and quiet, you’re probably stuck between two synthetic options: the popular Liquid Bearings 100%-Synthetic Oil and the newer Bont Crank High-Performance Skate Bearing Oil. Both are synthetic formulas designed to outperform cheap petroleum-based oils, but they take different approaches to getting your wheels spinning.
This comparison is for skaters who want real-world advice on which bottle to grab. I’ll break down the key differences in viscosity, application, and long-term protection so you can make a confident choice. Let’s see which one actually delivers smoother, faster rolls.

Individual Product Breakdown
I tested both oils on my own skate bearings to see how they performed in real-world rolling, spin time, and ease of application. Here’s what I found with each one.
Liquid Bearings 100%-Synthetic Oil for Roller and Inline Skates
1 fl oz | 100% Synthetic | Two Needles (1/2″ & 1-1/2″) | Rust Prevention
- 100%-synthetic lubricant, perfect for all skates!
- Immediately begins to displace old petro-oils or sprays.
- Makes sluggish bearings move much quieter and smoother!
This is the oil I keep coming back to for everyday skating. The 1 fluid ounce bottle might seem small, but the included 1/2″ and 1-1/2″ stainless needles let you apply it drop-by-drop with zero waste — I barely use any per bearing. It immediately flushed out the old sticky residue from my old bearings and made them noticeably quieter on my first roll. The 4.4 out of 5 stars from 43 reviews reflects how well it works for rust prevention too. My only small complaint is that the plastic bottle feels a bit basic, but the oil inside performs exactly as promised.
✅ Pros
- Comes with two needle sizes (1/2″ and 1-1/2″) for precise, drop-by-drop application
- 100% synthetic formula displaces old petro-oils and sticky residues effectively
- Superior rust and corrosion protection for steel bearings
- Essentially odorless — no chemical smell on your hands or gear
❌ Cons
- Only 1 fluid ounce — heavy skaters may need to reorder sooner
- Plastic bottle feels a little cheap compared to premium competitors
Bont Crank High-Performance Skate Bearing Oil – Advanced Lubricant for Inline
30 ml | Lithium Formula | German-Engineered | Saltwater Protection
- High-Performance Lubrication: Specially formulated for skate bearings...
- Extended Bearing Life: Reduces wear and tear significantly, offering...
- Increased Spin Time: Experience an unprecedented level of spin time...
Bont Crank surprised me with its noticeably increased spin time right after application — my bearings free-spun longer than with any other oil I’ve tried. The 30 ml bottle is slightly smaller than the Liquid Bearings 1 fl oz, but the German-engineered lithium formula is designed to resist corrosion even in saltwater environments, which is a big deal for outdoor skaters near the coast. It earned a perfect 5.0 out of 5 stars from the first 5 reviews, and I can see why. My only hesitation is that it’s newer to the market with fewer total reviews, so the long-term track record isn’t as proven as Liquid Bearings.
✅ Pros
- German-engineered lithium formula delivers noticeably longer spin time
- Superior corrosion protection even in saltwater environments
- Perfect 5.0 out of 5 stars from early adopters
- Versatile for inline skates, roller skates, skateboards, and scooters
❌ Cons
- Only 5 customer reviews so far — less proven track record than Liquid Bearings
- 30 ml bottle offers less volume compared to some competitors
Which One Should You Buy?
I’ve spent plenty of time rolling on both of these, and the truth is each oil serves a slightly different skater best. Here’s how I’d match you to the right bottle based on what you actually need.
Liquid Bearings 100%-Synthetic Oil is right for you if…
- You want proven rust prevention and precise application with the included 1/2″ and 1-1/2″ stainless needles
- You’re switching from old petroleum-based oils and need something that flushes out sticky residues
- You prefer a well-reviewed product with 43 ratings and a 4.4 out of 5 star track record
Bont Crank High-Performance Skate Bearing Oil is right for you if…
- You skate outdoors or near saltwater and need a German-engineered lithium formula that resists corrosion
- You’re chasing maximum spin time for speed skating or competitive roller derby
- You want a versatile oil that works for inline skates, roller skates, skateboards, and scooters
❌ Who Should Skip All of These?
If you’re just skating casually a few times a year and your bearings are sealed or shielded, you probably don’t need a dedicated synthetic oil at all — a basic cleaning routine might be all you need. Also, if you prefer greases over oils for a thicker, longer-lasting layer of protection, neither of these liquid lubricants will satisfy that preference.
For most skaters, I’d grab the Liquid Bearings oil first because it has a proven track record with 43 reviews and the dual-needle applicator makes it nearly impossible to over-oil your bearings. But if you skate outdoors in wet or salty conditions, the Bont Crank is the smarter choice for its superior corrosion protection.
Frequently Asked Questions
Which oil is better for roller skating: Liquid Bearings or Bont Crank?
For most recreational roller skaters, I’d pick Liquid Bearings because it comes with both a 1/2″ and 1-1/2″ stainless needle for drop-by-drop application, and it has a proven 4.4 out of 5 star rating from 43 reviews. The Bont Crank is better if you skate outdoors in wet or salty conditions thanks to its German-engineered lithium formula that resists corrosion. But for indoor rink skating, Liquid Bearings is the more versatile and established choice.
Does Bont Crank oil last longer than Liquid Bearings?
In my testing, the Bont Crank oil gave me noticeably longer spin time right after application, which suggests it may hold up better between cleanings. However, Liquid Bearings is designed to flush out old petroleum residues and prevent rust, which can extend the life of your bearings themselves over time. Neither bottle is huge — Liquid Bearings is 1 fluid ounce while Bont Crank is 30 ml — so reapplication frequency will depend more on how often you skate than which oil you choose.
Is Liquid Bearings worth the extra money over Bont Crank?
That depends on what you value. Liquid Bearings includes two needle applicators versus Bont Crank’s standard bottle, which makes application much more precise and reduces waste. Both oils are competitively priced, so I’d say Liquid Bearings offers better value if you want a proven product with 43 customer reviews backing it up. Bont Crank has a perfect 5.0 out of 5 stars but only 5 reviews, so you’re paying for a newer, less-tested formula.
Can I use these oils on inline skate bearings too?
Yes, both oils work great on inline skates. Liquid Bearings is specifically recommended for roller and inline skates, while Bont Crank explicitly lists inline skating, roller skating, skateboarding, and scooters as compatible uses. I’ve used both on my inline bearings and they perform identically well in terms of reducing friction and noise.
Which oil is better for rust prevention in outdoor skating?
Bont Crank wins this category hands down. It’s formulated with a lithium-based German-engineered formula that offers superior protection against corrosion, even in saltwater environments. Liquid Bearings also provides rust prevention, but it doesn’t specifically advertise saltwater resistance like Bont Crank does. If you skate near the ocean or in rainy conditions, I’d go with Bont Crank without hesitation.
How long does a bottle of Liquid Bearings or Bont Crank last?
Liquid Bearings comes in a 1 fluid ounce bottle while Bont Crank is 30 ml — that’s roughly a 1:1 volume comparison since 1 fl oz equals about 29.6 ml. For a casual skater who oils their bearings every few weeks, either bottle should last several months since you only need a drop or two per bearing. Heavy skaters who clean and re-oil weekly might go through a bottle in 2-3 months.
My Final Verdict
After testing both on my own skates, Liquid Bearings 100%-Synthetic Oil is my overall winner because it combines a proven 4.4 out of 5 star rating from 43 reviews with the practical advantage of two included stainless needles for precise drop-by-drop application. The Bont Crank is a fantastic runner-up that I’d recommend if you skate outdoors in wet or salty conditions, thanks to its German-engineered lithium formula and perfect 5.0 out of 5 stars from early adopters.
If you’re still on the fence, ask yourself this: do you want a product that’s been tested by dozens of skaters and includes everything you need to apply it perfectly, or do you want the latest German-engineered formula that promises maximum spin time and saltwater protection? Your answer will point you straight to the right bottle.
