🔁 Alternative sizes and chains

The size 300x109x40W should only be replaced with the same size: 300 mm width, 109 mm step, 40 links and W profile. It is not recommended to use close sizes such as 300x109x40N, 300x109x40K or standard 300x109x40, without checking on the old circuit.

In some catalogs, the size may be written as 300x109x40W, 300X109X40W, 300-109-40W, 300/40/109W or 300x40x109W. The meaning remains: width 300 mm, step 109 mm, 40 links and W profile.

The letter W is important, because it could mean a different internal driver or a wider/specific channel configuration than standard, K or N chain. Therefore, this size should not be replaced by N, K or standard variant without physical inspection 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.
