[Case Study] Wear Prevention Measures for Aluminum Sheaves and Guide Rolls with Dyneema

Wear prevention measures for aluminum sheaves (guide rolls) with Daikron.

We received your inquiry regarding the severe wear of the guide roll (sheave) for the carrier rope that guides the paper in the dry part of the paper machine at your paper manufacturing company. This wear causes the rope to frequently come off, disrupting production. Issues: 1. Since the carrier rope rotates alone, we would like to change the sheave from aluminum to iron or stainless steel to reduce wear, but the increased weight makes this change impossible. 2. We considered hard chrome plating, but it cannot be applied to aluminum substrates. (Direct electrolytic plating on aluminum is not possible, so a base plating must be applied first, which increases the risk of peeling when hard chrome plating is done on top.) 3. We want to maintain wear resistance even under high temperatures due to heat exposure. 4. Frequent replacements incur manufacturing and replacement costs.
