The product
Product overview.
The assembled and separated photographs show the bearing family’s water-drop profile and body arrangement. Compare those details with your installation, especially when an existing hinge has a similar outline but different internal parts.
Choose one complete entry from the 18-row size table. The reference drawing shows section views and dimension symbols; it is not a dimensioned drawing for every listed size. Send a marked sketch if a pin dimension, mounting position or clearance must match.
Include the door width, height, weight and hinge positions with your inquiry. The table records each hinge’s own mass, so it cannot be used as a door load rating.

Before you inquire
Useful answers.
Are all diameter and length combinations listed?
No. The table contains 18 specific entries, not every combination between the first and last sizes. Select a complete row. If it does not match your requirement, mark the requested dimensions on a drawing for review.
Does Bearing Type mean a particular ball-bearing design?
The catalog identifies a bearing assembly but does not specify the bearing type, model or material. If your design requires a particular internal arrangement, include a section view or component specification so it can be confirmed.
How much door weight can this hinge support?
A door load rating is not published here. For example, the ф16*100mm entry weighs 142 g; that is the hinge’s own mass. Send the door dimensions and weight, hinge count and positions, and an installation drawing for a suitability review.
Can I request a different size or configuration?
Send the closest listed entry with the requested change marked beside it. Include quantity and installation details. The proposed configuration needs Requirement / Specification Confirmation before it can be treated as an available option.
What should I attach to a bearing-hinge inquiry?
Attach the current drawing or a marked sketch showing the hinge, door and frame. Identify the exact size, fixed dimensions, quantity and any material, finish or bearing requirements. Use the form’s drawing and image fields, then check the submission result.
