This page explains how Hydraulic Gap Control is classified within Basic Metal Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
A hydraulic system that precisely controls the gap between work rolls in a rolling mill to achieve desired material thickness and quality.
Technical details and manufacturing context for Hydraulic Gap Control
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Maximum Rolling Force | 15000–30000 kN | Determines the maximum thickness reduction capability. |
| Gap Control Accuracy | ±0.01–±0.05 mm | Higher accuracy ensures tighter thickness tolerances. |
| Response Time | 10–50 ms | Faster response improves dynamic control performance. |
| Operating Pressure | 20–31.5 MPa | Below 20 MPa the system may not achieve required force. |
| Hydraulic Fluid Viscosity | 32–68 cSt | Viscosity affects pump efficiency and response.ISO 3448 |
| Operating Temperature Range | 5–60 °C | Outside this range, fluid viscosity changes affect performance. |
| Ingress Protection Rating | IP54–IP65 | Higher rating needed for dusty or wet environments.IEC 60529 |
| Supply Voltage | 380–480 V AC | Three-phase, 50/60 Hz.IEC 60038 |
| Control Signal | 4–20 mA | Analog signal for setpoint and feedback.IEC 60381 |
| Cylinder Stroke | 100–300 mm | Determines the range of gap adjustment. |
| System Weight | 5000–15000 kg | Affects installation and foundation requirements. |
| Fluid Cleanliness Level | ISO 4406 17/15/12–16/14/11 | Cleaner fluid extends component life.ISO 4406 |
Ranges are indicative industry figures for RFQ preparation, not a supplier commitment. Confirm every value and standard with the legal manufacturer before ordering.
This component is essential for the following industrial systems and equipment:
| pressure: | Up to 350 bar (max working pressure), 500 bar (peak transient) |
| flow rate: | 10-500 L/min (typical), depends on cylinder size and response time |
| temperature: | 0°C to 80°C (operating), -20°C to 100°C (storage) |
| response time: | 20-100 ms (for gap adjustment) |
| positioning accuracy: | ±0.001 mm (with feedback systems) |
Indicative industry ranges for design and RFQ preparation. Confirm the exact figures and applicable standard with the manufacturer before specifying.

Manufacturer profiles associated with Hydraulic Gap Control.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The reference range is 20–31.5 MPa. However, actual operating pressure must be confirmed for the specific model and application with the manufacturer.
The reference accuracy is ±0.01 to ±0.05 mm. This is a range; the exact tolerance depends on the system configuration and must be verified with the supplier.
The reference response time is 10–50 ms. Faster response improves dynamic control, but the actual value should be confirmed for your specific system.
Listed standards include ISO 3448 for viscosity, IEC 60529 for ingress protection, IEC 60038 for voltage, IEC 60381 for control signal, and ISO 4406 for fluid cleanliness. These are references for verification, not certifications.
