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.

Stylish and functional.
Color: Green, Color: Green
First, I love the color. Earth tones are my go to. This is a nice shade of olive green.
The design is stylish. Minimalistic is also my preference. It’s very much form and function.
So I’ve mostly used this hiking. It’s big enough to store everything I needed for longer or overnight trips. I had a light jacket, sunscreen, flashlight, bug spray, several bags of snacks, a book, wipes and a water bottle. I could have packed more honestly. It’s waterproof and the material doesn’t snag or scratch.
I’ve also used it for travel, mostly for my art supplies. It’s sturdy so my sketch book doesn’t bend. Theres a dozen different pockets and compartments, so everything can be separated from each other.
The size is good, the strap lengths are long and easily adjustable. The only downside is the compartment for a water bottle or travel mug is pretty tight. Other than that I like it a lot.

Good solid backpack
Color: Latte Beige, Color: Latte Beige
I’m really happy with this backpack. It fits my Lenovo Legion 5 16'' perfectly with just a little room to spare, but not so much that the laptop shifts around. The material feels sturdy and durable, and the waterproof design gives me peace of mind when I’m out and about.
The travel strap on the back is a huge plus for me—it makes traveling so much more comfortable. There’s also plenty of space for my things, and I can easily use it as a weekend bag for 1–2 days without it feeling bulky.
The price is not bad, for the quality you receiving is honestly really good. If you’re looking for a reliable, well‑made backpack with lots of room, this one is a great choice.

A really nice one!
Color: Latte Beige
This was so close to perfect for me! Love the fabric, the structure and the setup. I just didn't love the really thick padded laptop pocket. It made the bag bulky than necessary and I don't usually carry a laptop.
