4. FAQ

Q: Which track-type tractors and track roller components does this 9X-4582 seal kit match, and what sealing parts are contained in the kit?
A: This full oil seal kit fits D6 series track-type tractors and matching track skidders, specially designed for track roller frame oscillating sealing positions. It is an integrated assembly kit containing rubber main seal, steel outer shell, PU buffer ring and PTFE anti-wear ring. All matched sealing parts needed for track roller disassembly overhaul are packed together, eliminating the trouble of separately purchasing scattered accessories during on-site maintenance.

Q: What practical advantages do the composite structure of NBR, steel, PU and PTFE bring to track roller sealing?
A: Track-type tractors travel on muddy and rugged construction sites all year round, and track rollers bear continuous heavy load, frequent swing friction and erosion from mud, water and dust. The NBR main seal has strong oil resistance and elastic recovery to block lubricant leakage inside the roller. The outer steel shell provides rigid protection to prevent deformation and impact damage of the rubber seal. The PU buffer ring absorbs swing pressure impact to avoid tearing of the sealing lip. The PTFE anti-wear ring reduces friction during roller rotation and swing, effectively extending the overall service life of the seal assembly.

Q: What color and structural appearance features do each component of this seal kit have?
A: The outer steel protective shell is matte silver gray with uniform punching positioning holes. The inner NBR main sealing ring is solid black with integrated double-lip structure. The built-in PU buffer ring is light yellow with circular shock-absorbing outline. The thin PTFE anti-wear ring is milky white and closely attached to the rubber inner wall. The whole seal assembly is a one-piece circular integrated structure with standard unified dimensions, easy to install and locate during assembly.

Q: What stable working pressure and temperature range can this composite seal kit withstand?
A: This multi-material composite seal can continuously bear stable lubricating pressure up to 320 bar. NBR and PU components work normally within -33°C ~ +118°C, and the steel shell can resist extreme temperature changes without deformation. It can maintain reliable sealing performance in muddy low-temperature construction in winter and long-hour full-load earthmoving operation in summer, without rubber swelling, hardening or lubricant leakage.
