Cable Retraction with a Level-Wind Mechanism
Include its travel resistance, reversal behavior and cable guidance. Even orderly winding can add load to the return mechanism.
Cable Retraction Pull Force at Different Spool Layers
The effective spool radius changes as layers build or disappear. Spring torque must be evaluated together with that radius.
Power Spring Position-Specific Wear Investigation
Look for recurring geometry or contact at that position. Relate the mark to housing, attachment and winding state.
Power Spring Torque Drift After Repeated Conditioning
State whether torque is measured before or after a defined conditioning sequence. Compare like-for-like conditions.
Power Spring Packing Density and Coil Clearance
The coil occupies different envelopes through the winding window. Verify the state with least clearance as well as the parked condition.
Power Spring Load Reversal in a Bidirectional Mechanism
No. The approved winding range and load direction must explicitly include the intended bidirectional motion.
