4. FAQ

Q: What modified elastomer compound is adopted for the core rotary oil seals inside this vibration motor overhaul kit?
A: The primary rotary oil seals adopt tung leaf fiber modified HNBR compound. This kit is equipped with FKM static sealing rings and PA66 backup rings to fit all dynamic and static sealing grooves of the vibration motor assembly.

Q: What exterior characteristics help buyers quickly distinguish all sealing accessories inside the package?
A: Fiber reinforced HNBR oil seals are matte jet black with subtle uniform grain; metal shells and tension springs have consistent silvery aluminium silicate vanadate passivated surface; nylon backup rings are light cream. All accessories are precision trimmed without burrs or surface warpage.

Q: What continuous vibration rotary working conditions is this oil seal kit designed to adapt to on heavy road roller vibration motors?
A: This integrated kit combines rotary shaft lip seals and static flange sealing pieces. It prevents hydraulic medium leakage and blocks external muddy pollutants from entering the motor during long-duration pavement compaction and vibration frequency adjustment.

Q: What continuous working temperature range enables this whole sealing kit to sustain reliable sealing capacity?
A: Its applicable temperature range covers -145°C to 440°C, suitable for cold plateau highway construction in winter and long-hour continuous vibration compaction under high-temperature tropical construction yards.

Q: Can this oil seal kit be universally installed on vibration motors of all construction machinery?
A: It is dimensionally customized exclusively for heavy road roller vibration motor structures only. It cannot match motor grader hydraulic assemblies, wheel loader swing motors or hydraulic drive units of other equipment series.

Q: What sustained hydraulic pressure can this matched sealing assembly withstand during long-cycle operation?
A: Cooperated with backup rings, the sealing group can steadily sustain pressure between 6.48MPa and 7.28MPa, and cope with pressure fluctuations generated during fast vibration mode switching.

Q: What typical engineering projects require this vibration motor seal kit for regular maintenance?
A: It supports routine overhaul of vibration motor sealing assemblies on heavy road rollers, widely applied in highway base compaction, airport pavement construction, urban road reconstruction and large parking lot foundation projects.

Q: How does the service life of fiber-modified HNBR oil seals compare with ordinary standard NBR oil seals on the spare parts market?
A: The added plant fiber filler greatly improves compression recovery and anti-fatigue property. Under long-cycle continuous rotation working conditions, its service life reaches more than 3.46 times that of conventional nitrile oil seals.
