Single-Sided Tooth Timing Belt 30×1051La H=15mm CR + Aramid Fiber + Polyester Cord / Aramid Cord
This high-performance timing belt is designed for applications requiring precision, durability, and reliability. Constructed with a Chloroprene Rubber (CR) base and reinforced with Aramid fiber, this belt offers exceptional resistance to abrasion, oil, aging, and temperature changes. We offer two internal cord options tailored to different operating conditions:
Available in Two Reinforcement Types:
CR + Aramid Fiber + Polyester Cord
Ideal for standard machinery and general-purpose industrial equipment. Polyester cords provide reliable tensile strength, excellent dimensional stability, and cost-effectiveness. This variant is perfect for environments with moderate load and temperature conditions.
CR + Aramid Fiber + Aramid Cord
Built for demanding applications. Aramid cords offer superior tensile strength, minimal stretch, and outstanding resistance to high temperatures and dynamic stress. Choose this if your machinery operates under heavy load, high torque, or extreme environments.
Key Features:
Chloroprene Rubber (CR): Excellent weather, oil, and aging resistance
Aramid Fiber Reinforcement: High strength and minimal elongation
High Dimensional Stability: Consistent performance over time
Wear & Heat Resistance: Designed for long service life and reliability
Low Noise & Smooth Operation: Ideal for precision mechanical systems
How to Choose the Right Belt:
For general industrial use and cost efficiency, choose the Polyester Cord option.
For high-load, high-speed, or harsh environments, select the Aramid Cord version for maximum durability and performance.
Whether you're upgrading your current drive system or replacing a worn-out belt, choosing the right reinforcement will extend your equipment’s lifespan and ensure consistent operation.

Overall a really great toy for all sizes of dogs
Flavor Name: Original Jerky, Size: X-Large, Flavor Name: Original Jerky, Size: X-Large
I ordered this product on Thursday and it said that it was going to be at my house in a week , but to my suprise it got delivered on that Saturday. My puppy loves these nylon bones. She is a 12lb dog but I ordered the X-Large size, and she loves it! The nylon bones really work in keeping her teeth clean of tar for the most part, and she loves the flavoring inside. The only downfall is when she got to the marrow part it stained my light sheets. I replaced them with darker sheets and there is no trace of the bone. Overall a really great toy for all sizes of dogs!

The ONLY Bones/Chews Dog-Approved in Our House!
Flavor Name: Original Jerky, Size: X-Large
We have 2 purebred pitbulls, both adult males who weigh between 75-80 pounds. We bought a huge assortment of bones, treats, and chews when we first got our boys (they're rescues, and we got them at the same time). They strongly favored these Marrowchews, even over other, imitation products of different brands.
We actually didn't know they had marrow INSIDE the bones for quite some time, and as soon as we realized that, we understood why our dogs loved them so much! The way the marrow is embedded in the bone, but a ways in from either end, is really clever. The dogs can surely smell it long before they can taste it, and it seems to keep them really interested and motivated at first. Then, they get to the actual marrow, and they are working on these bones non-stop until it's completely gone. The way they are made is also really unique; they sort of 'splinter' as they get chewed, and it actually helps with doggie dental care, cleaning the teeth and massaging the gums. There is no mess with these bones, no pieces flaking or chunking off, anything like that. They are also completely odor-free. With other bones/chews, they'll start them, but lose interest really quickly, and never so much as look at those again. These specific Marrowchews are truly the ONLY ones that keep our dogs interested, and for a significant amount of time, too. They'll work on the XL sizes daily throughout the day for a total of 1-2 hours, and they last a couple of months, easily. And keep in mind, these are pretty
aggressive chewers!
HIGHLY recommend these, and the price on Amazon is the best anywhere!

Durable and fun
Flavor Name: Beef, Size: Medium/Large
I have two dogs and I only bought one bone over a month ago. They’ve both been chewing on it and it’s held up really well. I wouldn’t say they’re aggressive chewers, but they do like chewing.
They’re still picking it up and using it, so they’re definitely not bored with it. As for me, it’s been a pretty great buy.

Tough Chew!
Flavor Name: Original Jerky, Size: Medium
Sporn is a very tough chew. We have a 22pound Beagle 1 year old. She spend little time working on the Hard plastic that encases the marrow. Now I don't doubt there are some dogs that would chew this mindlessly for the small marrow treat. It is not for my pup! She needs more play to keep at it. A TOUGH CHEW would be better slightly less thick and more marrow inside. I attached a string and had her whirly birding around chasing this bone but once we let go she has a 30 second interest. Not for every dog maybe for the big guys 100 lb brutus !

Dogs are enjoying it!
Flavor Name: Beef, Size: Medium/Large
I just got this bone today but so far my dogs love it. They have been playing with it and alternating who’s chewing on it. My 8 month old got the blue rubber piece off in about 10 minutes, so if that’s the primary factor for purchasing, note that.
