As a result, equipment downtime was kept to a minimum, and the customer received a reliable supplier of KOM QH50-4211206-12 flanges with predictable deadlines and stable quality.
Frequently asked questions about the KOHM flange QH50-4211206-12
What material is the KOM QH50-4211206-12 flange made of?
The flange is made from alloy structural steel with subsequent heat treatment (hardening + tempering). This provides an optimal combination of hardness of the working surfaces and toughness of the core, which is critical for parts operating under variable loads.
Is this flange suitable for other modifications of the QH50 power take-off?
Yes, the QH50-4211206-12 flange is designed specifically for the QH50 series PTO line. However, we recommend that you check the exact modification of your power take-off before ordering so that we can confirm compatibility by reference to the part number.
What tightening torque is recommended when installing a flange?
The recommended tightening torque for the flange mounting bolts is from 80 to 120 Nm, depending on the size of the fastener and the recommendations of the KOM manufacturer. Before installation, be sure to clean the mating surfaces and replace the O-ring if present.
How to distinguish an original flange from a fake?
The original flange KOM QH50-4211206-12 has a clear marking of the article, smooth machined surfaces without cavities and traces of rough casting. Additionally, the weight of the part is within factory specifications. We provide photos and measurements prior to shipment upon request.
What is the service life of the KOM QH50-4211206-12 flange?
Subject to the recommended operating conditions and timely maintenance of the PTO flange, the service life is at least 80,000–120,000 km. The service life depends on the intensity of use of the power take-off and operating conditions of the equipment.
