Please consider replacing AS series with SS series

SS series was renewed in October 2022 and now the performance is equivalent or more to AS series.

RS ：RS40～RS100、Double Pitch Chains ：RF2040～RF2080

Wear life

SS series has longer life than AS series.

AS has pre lubricated for rust prevention purpose while SS has not.

AS series has longer life in that case, comparing pre lubricated AS and non pre lubricated SS series.

The users using without degreasing or lubricating additionally, lubrication is required even with the new SS series.

We can pre lube for new SS series upon request. (Special order )

Since the materials used for SS and AS series are different, replacing them with SS series will reduce the strength of the pins.

Calculation of pin strength selection is available upon request. Please contact us.
