HIMOD®ADVANCED COMPOSITE BEARINGS ■ General Description ■ General Description HiMod®Advanced Composite Bearings (HiMod®ACB) are a high-performance solution for bearing, wear ring, bushing, and thrust washer applications manufactured using Automated Fiber Placement (AFP) technology. The in-situ additive manufacturing process uses high-quality, pre-impregnated tape for a robust and low friction bearing solution. Two types are available depending on friction requirements: ACB Standard, which uses a carbon fiber/PEEK tape, and ACB+ with an additional low friction PEEK layer. Both versions use selected...

MPa-m/min (psi-ft/min) Reached test machine limit before failure Table 1: Bearing Properties Summary HiMod®ACB raw material is unidirectional continuous carbon fiber reinforced PEEK, 60% fiber volume. Test conditions are at +23 °C / +73 °F, ambient. Friction and wear properties vary with test method, countersurface material, roughness, ambient conditions, and PV combination. TRELLEBORG SEALING SOLUTIONS • 11 Latest information available at www.trelleborg.com/seals • Edition January 2024 Two primary types are available to cover most applications: Continuous carbon fiber / PEEK structural layer....
