Rubber instead of steel chains are usually used on mini excavators and excavators. Why this is so and what advantages rubbing arches have to offer, you can here Feel free to read again. If you are now looking for a new rubber die for your machine, it is easiest to enter the manufacturer and the model of your excavator or the dimensions or article number of your old rubber room directly via our search bar. It is often the case that, for example, several chain sizes are displayed that fit your excavator, and you may be unsure about which is now the right chain. Perhaps you can no longer read the dimensions of the rubber arch by wear or weathering. But that is also not a problem: With our instructions you can easily find out which chain size fits your machine and then order it directly on Baumashop24.
So you measure the rubber arches
Basically, rubber arches are based on the scheme Width x length x division (number of chain members) Described, e.g. 500x92x84.
- The width of the rubber arches is given in millimeters, you can simply measure this.
- The length is the distance between two chain members. You measure from the beginning of a chain member to the beginning of the next chain member, also in millimeters.
- The division is about the number of chain members, simply count them.
Now you can simply enter the dimensions in the search bar on Baumashop24.com and the right rubber arches are displayed. In addition, the product description also includes the models to which the respective chain fits so that you can reinsure yourself again.
You have to consider these special features
Some rubber bins are also marked with a letter (B, K, N, T, W or Y). It does not matter where the letter is, i.e. 500x92kx84 and 500x92x84k are the same chains.
The letters Y, T and B are used for models from the manufacturer Yanmar (Y), Takeuchi (T) and Bobcat (B).
K, N and W relate to the leadership of the chain. When the rollers run outside (external), they are marked with a K. In the case of internal chains, the letters are available and W. n is derived from the English "Narrow" and stands for a narrow track (approx. 40 mm). W, on the other hand, stands for "wide", i.e. a wide track (from 50 mm).
Long-Pitch and Short-Pitch
Finally there are differences in the division of the rubber arches. With short-pitch chains, the individual chain members are shorter than with long-pitch chains, which leads to better rolling behavior and lets the machine run calmer. If you are currently traveling with a long pitch chain, you can usually convert them to a short-pitch rubber arch. It is only important that the total length of the chain remains the same. So if you currently use a chain with the dimensions 230x96x33 (long-pitch), you can usually also order a chain with the dimensions 230x96x66. The chain members (33) are only half as long for the short-pitch chain, accordingly there are twice as many of them (66) so that the chain length remains the same.
