🔁 Alternative sizes and chains

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

In some catalogs, the size may be written as 300×52.5x78W, 300X52.5X78W, 300-52.5-78W, 300/52.5/78W or 300x78x52.5W. The meaning remains: width 300 mm, step 52.5 mm, 78 links and W profile.

The letter W is important, because it may mean a different internal driver or a specific channel configuration versus a standard one, N или WK верига. Therefore, this size should not be replaced by N, WK или стандартен вариант без физическа проверка по старата верига.

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.
