🔁 Alternative sizes and chains

The size 300×52.5x78WK should only be replaced with the same size: 300 mm width, 52.5 mm step, 78 units and WK profile. It is not recommended to use close sizes such as 300×52.5x78N, 300×52.5x78W or standard 300×52.5×78, without checking on the old circuit.

In some catalogs, the size may be written as 300×52.5x78WK, 300X52.5X78WK, 300-52.5-78WK, 300/52.5/78WK or 300x78x52.5WK. The meaning remains: width 300 mm, step 52.5 mm, 78 units and WK profile.

The designation WK not to be missed. It may mean a different internal profile, different conductor configuration or specific circuit guidance relative to N, W or standard version. Therefore, this size should not be replaced by another profile variant without physical verification on the old circuit.

Before ordering it is important to compare the inscription on the old chain, the width, the step, the number of units, the inner guide, the profile and model of the machine. If the profile doesn't match, the chain may not seat properly on the undercarriage.
