When the excavator hydraulic pump is seriously worn, it has a fatal effect on the excavator, so the excavator must solve such problems in time. When troubleshooting the hydraulic pump of the excavator, look for the cause of the fault from the following...
Spherical roller bearings have high load carrying capacity and can withstand high running speeds. The raceways are spherical and have automatic self-aligning function, which can compensate for bearing eccentricity caused by installation of different...
Maintenance free NSK's maintenance-free ball bearing unit is sealed with a high-quality lithium base grease suitable for use in sealed bearings for long-term use. The sealing device with excellent sealing on the bearing not only prevents leakage of...
Bearings (Western writing "bearing", the Japanese called "axis") is a very important component in contemporary mechanical equipment. Its main function is to support the rotating shaft or other moving body, to guide the rotation or movement and to bear the...
High-speed precision angular contact ball bearings are mainly used for high-speed rotating applications with light loads. High-precision bearings, high-speed, low-temperature, low-rise vibration and a certain service life are required. The support members...
