I do appreciate the lot of goods of Monotaro because we do not sell very thin v-belts

On the drill press

Where the V belt which was hardened and deteriorated was exchanged, the sound became quiet and vibration almost disappeared. I think that it is reasonable and very good product.

Three-roller loaded belt with load
From Japan
On 2017-11-20 17:06:51
I exchanged because the belt deteriorated because of the load of three poster rollers. After installation, the load that had deteriorated and became light became original. Because the price is also cheap, I would like to exchange regularly in the future as well.

Manufacturer's genuine replacement parts (same standard) price is also high and high, it is necessary for several weeks to place orders. I am saved.

I changed the spindle's axis, so I bought it for replacement.

Although there is no problem with the product, it did not understand the size of the belt, it was purchased as an estimate, so it was longer than I thought, then K40 was a little longer then K39, just Just Fit (eventually purchased 3 sizes). It may be useful if there is a guide table of the belt size or a calculation formula.

Belt change of tabletop drilling machine
From Japan
On 2016-08-05 08:11:21
Because vibration of M base desk drilling board TB131 is large and it is hard to make a change, I tried changing the belt. The attached one is K28.5 which is very difficult to obtain with extremely dimensions and therefore purchased K28 and K29. In K28, the tension was strong and vibrations increased conversely. Although the tension is loose in K29, you can use it if you adjust your eyes by adjustment. Vibration is about to receive a somewhat reduced feeling. I wonder why M company adopted a belt difficult to obtain. It seems that the accuracy of the old drilling machine was better. The belt of K29 is a good product and it does not matter.
