Cassette Recorder Rubber Belts, 40-135MM Mix Package, Width 3MM, 50 Pcs

Used this to fix my old cassette deck. It was a great value for the price. Belt size, thickness, and stretchability were perfect, and it works with my system like a dream. Would recommend.

Wonderful assortment of 4 mm wide belts in about 4 or 5 different lengths. The old belts disintergrate with age! Its amazing to see the black goo when you unscrew the cover. The key is you need to carefully remove and clean all that black goo on the pulleys before installing new belts. Aiwa really made it easy to disassemble and slide out the pulleys that go around the motor hub. Fix your old equipment because the new tape players are poor quality! Oh they have different width 4 mm is the widest about a fat 1/8” wide!

I repair donated, but non-functional items for a local thrift to sell. I used one of these flat ribbon-like belts to repair a 40 year old AIWA tape deck whose belts had turned into a tarry goo. Although these belts were not specifically designed for this tape deck, I found one that fit well enough and the deck is working great now. I found an exact match for the AIWA belt online, but it cost $30, so this set of 50 for under ten dollars was a no brainer. The belts are thin and feel slightly tacky. They feel less elastic than some rubber belts and I expect that over time they will also turn into black goo. However, the deck works well enough for the thrift to sell it and I have a lot of spare belts for the next cassette deck that needs a replacement belt.

Haven’t used them yet .. but the sizes are great to use on alotta stuff ..

Couldn’t find any dedicated belt replacement sets for this cassette deck in the US. Purchased this set of belts in hopes I could find a suitable replacement. Needed a 4mm wide belt. The longest included belt (there were multiples of this size in the package) worked. For some reason, the original belt turned to goo. Similar reports from others. The counter uses a smaller round or square belt that did not need replacing. Another kit of this (round/square) type of belt would probably work. For the routing: belt goes around the motor pulley, over top of the adjacent flywheel, and around the outer flywheel.

Great assortment!

I am no expert on rubber belts but I do understand basic geometry. I thought there were mainly two ways to describe a circle: circumference or diameter/radius. When I ordered these, I had both numbers and thought that the diameters were given but I was wrong. It appears that another way to describe belts such as these is the "folded length" or such. As a results, these belts are a lot smaller than what I thought. I believed the 90mm belt would be a good fit but it turned out that the largest, 135mm, barely was big enough. Not only that, the thickness is also much thinner than I anticipated. Again, probably my fault for not being more careful. The belts themselves seem to be of decent quality though. I'm just disappointed that they are a lot smaller and flimsier than I was hoping for. Not sure I'd trust them to operate a cassette deck, maybe a walkman, but that's it.

These belts are very low quality and won't last very long. I personally wouldn't recommend them for anything high-end and won't be purchasing them again. It's like they're pre dry-rotted. Please save your money for higher quality belts.

古いカセットテープレコーダ修理用として購入しました。サイズが分からないので多くのサイズの種類があるの中で現物合わせで修理が出来るのでとても重宝です。購入価格からはこの種類の多さは満足できるものです。

かなりの本数が入っていて、サイズはだいたい賄えると思います。 写真 左はこの製品、右は正規品。 実物は正規品に比べてやや粗いかなという製品です。 伸縮について、正規品はあまり伸び縮みしませんが、こちらは伸び縮みもけっこうあり、輪ゴムの平形版という感じ。 表面も“ゴム”なので、ややベタつきます。ベルトのスリップを利用したクラッチ構造を取る部分に使用すると空回りせず危険かも知れません。 今回はそのような部分ではなかったので交換して修理、正常に使用できました。 耐久性はまだわかりません。

The belts received are of good quality but a little costly

この手の物ははじめての購入。少し伸ばすと切れるものもあった。種類が色々入っているのがいい。
