Application
For heavy - duty trucks, buses, and construction vehicles, hub units are designed for extreme durability and load capacity. They withstand massive radial/axial loads from heavy payloads, frequent starts/stops, and rough terrains. Reinforced bearings, thickened flanges, and advanced sealing resist impact, dust, and water ingress. They also handle repeated braking torque, ensuring consistent performance during long - distance transportation and harsh - environment operations. This reliability reduces downtime, lowers maintenance costs, and guarantees safe, efficient operation for commercial fleets with high mileage demands.
For the bolt slippage test, the hub bearing unit is installed on the test device, and a torque of 150 N·m is applied to the bolt.
The thread is observed to see if it is damaged or if the bolt rotates relative to the bearing flange.
FAQ
Q: What is your sample policy?
A: We can offer one free samples, but it will be charged at first and the amount will be reduced in official order.
Q: What is your terms of payments?
A: We accept T/T L/C at beginning, 30% advance, and pay up before delivery.
For the bolt pull-out test, first mount the hub bearing unit onto the take a look at setup. Then observe a 4900N pressure alongside the bolt's axial path at a fee of 2mm per second. Check if the bolt pulls out relative to the bearing flange. Keep making use of axial pressure to the bolt till it comes loose, then report how the pressure adjustments till pull-out and notice the most pressure value.
Hub unit type tests include (triggered periodically/by batch): durability, sealing, vibration, ABS signal, comprehensive heat treatment items.
Hub unit after strength test / fatigue test: Pass criteria is flange with no cracks.
Application
Relying on high-precision bloodless heading forming science and extremely good bearing metal material, this wheel hub unit has top notch high-load bearing capacity, which can correctly undergo automobile weight, using influence force, radial and axial loads. After rigorous fatigue existence testing, its provider existence is some distance past the fundamental enterprise standards. Even underneath complicated street stipulations (such as bumpy roads, steep slope driving), it can preserve steady operation and make sure riding protection and reliability.
