Double-Sided Timing Belt 37×1162La H Profile 16mm Height Options with CR Rubber or EPDM Rubber Reinforced with Aramid Fiber and Polyester or Aramid Cord
This high-performance double-sided timing belt features dimensions of 37×1162La with an H-profile tooth height of 16mm, designed to provide precise synchronous power transmission and enhanced load capacity in complex drive systems requiring bidirectional engagement.
Material Composition and Key Features
CR (Chloroprene) Rubber with Aramid Fiber and Polyester Cord:
Offers excellent resistance to oil, heat, ozone, and abrasion. The CR rubber surface provides durable wear resistance, while the aramid fiber reinforcement ensures superior tensile strength. The polyester cord core balances strength with flexibility, making it suitable for dynamic applications with moderate mechanical loads and high-speed operation.
EPDM (Ethylene Propylene Diene Monomer) Rubber with Aramid Fiber and Aramid Cord:
Known for outstanding resistance to heat, weathering, ozone, and chemical corrosion, EPDM rubber extends belt longevity under harsh environmental conditions. Coupled with aramid fiber reinforcement and a high-strength aramid cord tensile member, this belt offers exceptional dimensional stability, tensile strength, and minimal elongation, ideal for heavy-duty or precision-critical applications.
Key Selling Points
Double-Sided Tooth Design:
Enables reliable power transmission on both sides, ideal for complex machinery where dual engagement is necessary.
High Wear and Heat Resistance:
Both CR and EPDM rubber compounds provide robust resistance to surface wear and elevated temperatures, extending belt life.
Superior Tensile Strength and Low Stretch:
Aramid fiber reinforcement and cords ensure the belt maintains precise timing and resists deformation, even under high loads.
Chemical and Weather Resistance:
Especially with EPDM, the belt withstands exposure to acids, alkalis, ozone, and harsh weather conditions without degradation.
How to Choose Between These Belts
Choose CR + Aramid Fiber + Polyester Cord when your application demands excellent wear resistance, good flexibility, and moderate temperature resistance. This option is cost-effective and suitable for industrial machines with moderate load and speed requirements.
Choose EPDM + Aramid Fiber + Aramid Cord for applications requiring superior heat, chemical, and environmental resistance, combined with maximum tensile strength and minimal elongation. This belt is recommended for heavy-duty, outdoor, or chemically aggressive environments where belt longevity and precision are critical.
In summary, these double-sided timing belts provide tailored solutions for diverse industrial applications, combining material innovations with design precision to deliver reliable, efficient, and durable power transmission.

Mixed Results
These strips fit comfortably and don’t slide around, which I appreciated. They are gentle on my gums and enamel, and I noticed a slight improvement in brightness after consistent use. That said, they aren’t as strong as some other whitening strips on the market, so if you’re looking for dramatic results you may be underwhelmed. Good for subtle whitening.

Does work well for removing minor stains
This product is probably best for removing minor staining - things like coffee, tea, red wine. I don't think it would work for longer-term stains that accumulate with age - the strips are not powerful enough for that.
Very easy to use: just apply and leave on for half an hour or until you can feel that they are no longer well-attached. The "cleaning" process starts immediately - you can see the bubbles form. I am a tea drinker, and I notice immediate effect after putting these on. Don't expect miracles, but they will help with fresh stains for sure.
For me, they do not increase the sensitivity, but my teeth are generally not sensitive. But they are peroxide based, so the possibility is always there that it could have that side effect.

Actually Works! Noticeable Results Quickly
THESE WORK GREAT! I’m a smoker and occasional coffee drinker, and these strips got my teeth from a 12 to a 9 in just a week—I actually noticed results right away. I don’t use them every day, but even with sporadic use, the difference is clear.
A couple of downsides: a few strips didn’t stick perfectly, but most stayed in place well.
The upsides: I have very sensitive teeth (I can’t even drink ice-cold water easily), and even when I left the strips on longer than recommended, I had very little to no sensitivity. Another bonus is that they’re stretchy! I’ve tried other well-known brands, and their strips had no stretch and often left my back teeth exposed.
Overall, these are effective, comfortable, and easy to use—I definitely recommend them!

Finally, whitening strips that work for me
I normally have not been able to use whitening strips due my teeth and gums being sensitive, but that hasn't been a problem with these pleasant-tasting strips. They really stick well on the teeth, takes a little effort to get them off in fact but that's not a complaint. Of course the main thing is that they whiten the teeth and while my teeth are probably a little harder to whiten due to my copious use of coffee and tea I can say that these have definitely whitened my teeth a couple shades since using them. Would definitely use again.

Before & After: Brighter, Whiter Smile in 14 Days
I used these consistently for the full 2-week treatment, and I’m really impressed with the results! As you can see in my before-and-after photo, the difference is very noticeable. The strips were easy to apply and remove, and I typically left them on for 30 minutes each night before rinsing -- they stayed securely in place the whole time and didn’t leave behind any sticky residue, which made them even more comfortable to use.
I have somewhat sensitive teeth, and while I experienced a little extra sensitivity on just a couple of days, it wasn’t too bad and went away quickly. A few days after finishing the kit, I haven’t had any lasting sensitivity issues—and my teeth are still looking just as white. I also really liked the refreshing mint flavor, which made the process feel clean and pleasant. Overall, this kit is a great choice if you want an effective whitening option that’s enamel-safe and easy to use. I’d definitely recommend it for tackling coffee, wine, or tobacco stains.
