Materials of DUHUI Hydraulic Release Bearings.
DUHUI hydraulic release bearings are mainly made of GCR15 bearing steel and combined with heat treatment and surface coating processes. The surface hardness meets the standards, and the corrosion resistance and wear resistance are greatly improved. We prefer to use seals made of FKM rubber from ISO 9001 certified suppliers to ensure that hydraulic oil does not leak.
Hydraulic System of DUHUI Hydraulic Release Bearings
The hydraulic system is a key component that distinguishes hydraulic release bearings from traditional clutch release bearings. The integrated hydraulic system of DUHUI hydraulic release bearings has obvious advantages over ordinary hydraulic release bearings. The structural integration is more lightweight, reduces the load, and improves energy efficiency. In addition, the hydraulic transmission effect is better and more stable.
Professional Testing of DUHUI Hydraulic Release Bearings
DUHU hydraulic release bearings will undergo a variety of targeted tests before leaving the factory, which are mainly divided into product standard testing and performance testing. We test the axial clearance tolerance of bearings according to ISO199 standard, requiring the static tolerance to be ≤0.05mm and the dynamic tolerance to be ≤0.15mm. We test the rotational torque of bearings according to ISO6798 standard, which is ≤1.2Nm at room temperature without load and ≤3.5Nm under load. We also conduct targeted performance tests such as wear resistance testing, durability testing, sealing testing and fatigue testing.
The main advantages of DUHUI hydraulic release bearings are easier operation and faster response. They are extremely effective in critical situations. They also provide a comfortable daily experience.
Under normal use, high-quality DUHU hydraulic release bearings have a service life of up to 3 years/80,000 kilometers.
Due to the different structures of hydraulic release bearings and clutch release bearings, their symptoms differ slightly.
If a hydraulic release bearing fails, it’s likely a problem with the hydraulic system. Pay attention to the following symptoms:
- The pedal feels light or heavy when pressed, and rebounds slowly.
- The clutch reacts slowly after you press the pedal.
- Some cars that require the clutch to start may have difficulty starting.
