Frequently Asked Questions

Quick answers about HANN products, codes and how to find the right part.

What does HANN Otomotiv manufacture?

HANN Otomotiv manufactures heavy-duty air suspension bellows (air springs), shock absorbers, filters and brake systems for commercial vehicles such as trucks, trailers and buses. The products are engineered and quality-controlled in Bursa, Türkiye, and delivered worldwide since 2013.

What is an air suspension bellows (air spring)?

An air suspension bellows is a flexible component between the vehicle's chassis and axle that works with compressed air. It carries the load, keeps the vehicle at the correct height, absorbs road impacts and improves ride comfort and safety on heavy commercial vehicles.

How do I find the right HANN part by OEM or cross-reference number?

Use the product search on hannotomotiv.com and enter the HANN code, OEM reference, cross-reference or vehicle type. The search ignores spaces, dots and dashes, so "1 D 28 F-5", "1.D.28.F-5" and "1D28F5" all return the same product.

What is a HANN code?

The HANN code (for example H01.1285.S) is HANN's own product reference. Each product page also lists OEM references (original-equipment numbers) and cross-references (equivalent codes from other brands) so you can match the correct part.

Which vehicles do HANN products fit?

HANN produces parts for heavy commercial vehicles — trailers, trucks and buses — covering air suspension, damping, filtration and braking applications.

Does HANN deliver worldwide?

Yes. From Bursa, Türkiye, HANN supplies distributors, dealers and fleets in many countries across every continent, focused on the heavy-duty commercial vehicle aftermarket.

Is HANN quality-certified?

Yes. HANN operates under internationally recognised ISO management systems — ISO 9001 (quality), ISO 14001 (environment) and ISO 45001 (occupational health & safety) — with quality control across design, production and final inspection.

How can I become a HANN dealer or distributor?

You can apply through the Dealership & Distribution page on hannotomotiv.com, or contact the export team via the contact form, phone or email. HANN builds long-term partnerships with growth-focused distributors in new markets.

What is the difference between an OEM reference and a cross-reference number?

An OEM reference is the original-equipment part number used by the vehicle or axle manufacturer. A cross-reference is the equivalent code used by other brands for a compatible part. Every HANN product page lists both the OEM references and the cross-references for its HANN code, so you can match an existing number to the correct HANN part.

What information do I need to identify the correct HANN part?

Any one of these is usually enough: the HANN code, an OEM reference number, a competitor cross-reference number, or the vehicle make and application. Enter it in the product search on hannotomotiv.com and the matching product will appear; spaces, dots and dashes are ignored.

How can I request a quotation or check availability?

Send your part list — HANN codes, OEM or cross-reference numbers and quantities — through the contact form on hannotomotiv.com, or reach the export team by email or phone. Include your country and destination so the team can advise on delivery.
