Caution

When making alterations to the insert side of EK-R EK-R-SUS (reamed type) use the countersinking hole on the side of the hub for machining of a fixing-pin hole.
A countersinking hole is added to the end surface of the EK-N boss.
The material properties of the resin may degrade when used under high temperatures or high humidity conditions.
