Wear resistant, anti-fire (e) Seals: grease retaining inner seal with multi-stage labyrinth and retention cap with outboard rubbing flinger seal (f) Lubrication: grease is lithium soap type grease with rust inhibitors (g) Welding: mixed gas shielded arc welding end (h) Our roller saves on repair and maintenance costs of the conveyor belt due to the concentric design which decreases vibration Advantage: (1). High accurate steel pipes ensure the rollers with low vibration and noise.(2) Multi-labyrinth seals achieve waterproof and dust proof.(3). Adopt good bearing make sure the long lifetime, stable running and good quality.
