hot sale PC200-7 KOMATSU Upper Roller Standard Maintenance Free

Lifetime lubrication: Pre-filled with high-performance lithium complex grease (NLGI 2) sealed in a permanently closed system, eliminating the need for periodic re-greasing. Advanced sealing system: Double floating seals (high-chromium alloy, HRC 65–70) paired with FKM O-rings (resistant to -20°C to 200°C) to prevent oil leakage and block contaminants (dust, mud, water). Precision Engineering: Smooth tread finish (Ra ≤ 0.8 μm) reduces friction between the roller and track chain, extending service life for both components. Symmetrical flange design to guide the track chain and prevent lateral misalignment during operation. Load Capacity: Designed to handle the track tension and dynamic loads of the Komatsu PC200-7 (operating weight: ~20 tons), with a static load rating of 8–10 tons per roller.
