description

This original roller adopts integrally assembled structure with wear-resistant cast steel wheel body and built-in sealed bearing assembly. The rolling surface is strengthened by medium-frequency induction quenching for outstanding wear and impact resistance. Built-in contact seals block fine asphalt particles, silt and dust from entering the bearing cavity and prevent grease leakage and premature bearing burnout. During long continuous feeding of the paver, the roller rotates together with the chain continuously, converting sliding friction into rolling friction and alleviating chain wear. If the roller runs with concave worn surface, seized bearing, leaking seal or cracked wheel body, the chain will scrape the base plate continuously and accelerate the wear of the whole feeding assembly. Inspection and replacement are recommended during overhaul.

advantage

- Original forming dimension with accurate mounting holes for direct replacement without modification
- Quenched rolling surface with high hardness to resist continuous chain friction for longer service life
- Built-in sealed bearing assembly provides dust and mud resistance for harsh asphalt site conditions
- Converts sliding friction into rolling friction to reduce wear on chain and base plate and lower power consumption
- Modular assembly for easy disassembly and assembly and shorter on-site downtime

FAQ

Q: Can a roller with slightly stiff rotation keep working?
A: Short-term observation is allowed if it only rotates a little tight without oil leakage and intact surface. Replace it immediately if it seizes, makes abnormal noise or leaks, to avoid scratching the chain and liner.

Q: Is it necessary to remove the chain to replace the roller?
A: It depends on installation space. Usually the chain tension can be loosened to create clearance. Partial chain removal is required if interference exists.

Q: Does the roller need regular grease filling?
A: It is pre-greased and sealed, and re-lubrication is not required under normal conditions. Once seals fail, grease filling cannot block contaminants and full replacement is required.

Q: Can rollers for left and right sides be interchanged?
A: Interchange is permitted with identical part numbers. Rotate the chain manually after installation to confirm smooth rotation without scraping.
