bearing cages, seal rings and matched shim samples from Tianjin to the Netherlands by air freight: material-lot control, roundness protection and grease-condition declaration

Define the actual bearing cages, seal rings and matched shim samples

Index part number, bearing family, material, dimension, lot, surface condition and sample purpose. Thin cages and shims that look similar need drawing or measured identifiers; clean new items, oiled samples and tested returns carry different status.

Packing for material-lot control, roundness protection and grease-condition declaration

Hold thin cages in formed ring supports so stacked weight bypasses the cage bars. Keep seal rings flat or in suitable trays without stretching them, and clamp shim sets between rigid sheets while preserving their thickness sequence.

Handover checklist in Tianjin

Use compatible leak-resistant bags for oiled parts and keep them away from paper reports. Inner-box IDs link lot and part number; a movement check before sealing should reveal loose rings or migrating shim packs.

• Exact item name, material, use and model
• Project, revision, specification, lot and quantity
• Evidence of material-lot control, roundness protection and grease-condition declaration
• Inner-position, carton and photograph mapping
• Truthful transport-property declaration
• Final gross weight and outer dimensions
• Tianjin handover point and ready time
• the Netherlands postcode, department, appointment and unloading conditions

Confirm air freight with final package data

For bearing sample work, preserve the relationship between cage lot, seal compound and shim stack instead of grouping by outside diameter alone. Thin cage bars need clearance from lids and dividers; elastomer seals remain relaxed, and a shim stack is banded in its measured order. State whether oil is a protective film, assembly grease or test residue. The Dutch quality group should quarantine a leaking inner bag with its entire lot label so cleaning does not erase the evidence needed to interpret later measurements.

Receipt and evidence in the Netherlands

The Netherlands quality team should examine roundness, seal shape and bag leakage before testing. Deformation, rust, oil escape or a lot mismatch requires whole-box isolation and evidence before cleaning or remeasurement.
