What certification do your precision bearings need for Germany and Sweden? Most buyers start with three: an ISO 9001 quality system, ISO 492 / EN 12080 dimensional tolerances, and RoHS / REACH material declarations — and one clarification matters more than the rest: CE marking applies to the assembled machine, not to
Common market-entry requirements; applicability and documentation are subject to the destination country's current regulations and mutual confirmation.
ISO 9001 documentation, EN 12080 tolerance control and 100Cr6 bearing steel make this precision bearing manufacturer auditable for German and Swedish OEM buyers. Below is what a supplier audit can actually check: process records, equipment, inspection data and delivery commitment.
Each lot ships with heat-treatment and dimensional records traceable to ISO 9001 documentation.
Angular contact ball bearings are produced to EN 12080 and ISO 492 P4 spindle tolerance grades.
100Cr6 bearing steel, controlled quench depth and hardness verification per heat number.
CNC centreless and internal grinders size bores and races in-process, holding bore and fit tolerances.
Roundness, runout, clearance and hardness reports are issued per purchase order and heat number.
Standard catalogue and repeat OEM orders ship in 4 to 6 weeks from Ningbo to Germany and Sweden.
Send model, bore and housing dimensions, load, speed, lubrication and duty. You receive a bearing selection proposal with accuracy class and expected life.
We confirm dimensions, tolerances to ISO 492 and EN 12080, internal clearance, preload and 100Cr6 steel grade. You get an approved dimensional drawing for sign-off.
Unit pricing per piece, tooling or setup charges, MOQ and a production slot. You receive a written quotation with the confirmed delivery date.
Grinding, superfinishing and assembly under an IATF-aligned quality system. You get a batch record covering hardness, roughness and measured dimensions.
Optional SGS, TÜV or customer-witnessed inspection before packing. You receive the inspection report with measured values, not a pass statement.
Export packing, HS code, EUR1 or declaration documents and the packing list. You receive the bill of lading, certificate of conformity and full traceable records.
20 pieces per bore size for standard 60xx, 62xx and 70xx series; one piece for sample evaluation. Mixed sizes can share one order line to reach the MOQ.
4–6 weeks ex-works Ningbo for standard ground bearings, 7–9 weeks for P4 spindle pairs and custom preload sets. Confirmed date issued with order acknowledgement.
Yes — 1–3 samples free of charge, buyer pays courier. Samples ship within 10 working days with dimensional and runout report so your engineers can verify fit and tolerance class.
ISO 492 P6, P5 and P4 as standard; EN 12080 tolerance classes for axlebox and gearbox builds on request. Each batch ships with dimensional and runout report plus EN 10204 3.1 steel certificate for 100Cr6.
Individual anti-corrosion bag, single box, then carton on pallet; grease-filled sets sealed. Documents: packing list, commercial invoice, HS code, material certificate, and declaration of conformity where CE marking applies.
30% T/T deposit, 70% before shipment; net 30 days after three completed orders. 24-month warranty on raceway and rolling element defects, claims handled by replacement in the next shipment.
