Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Standard batches of CHG Bearing 618/800 conform strictly to ISO Class Normal (ABEC-1). For high-precision machine tool spindles, gearboxes, or robotics requiring tighter runouts, CHG Bearing can provide custom batches graded to ISO Class 6 (P6/ABEC-3) or ISO Class 5 (P5/ABEC-5) with 100% micrometer verification.
For international ocean and air freight, CHG Bearing packs 618/800 with industrial VCI anti-corrosion barrier wrapping, sealed polybags, individual cartons, and fumigated ocean-worthy wooden crates. This multi-layer barrier guarantees rust-free storage for a minimum shelf life of 24 to 36 months.
Following standard ISO 281 fatigue calculation guidelines, the nominal rating life (L10) of CHG Bearing 618/800 correlates its dynamic capacity (standard dynamic) with equivalent dynamic loads. In controlled industrial settings with proper contamination-free filtration, field data confirms continuous operational longevity exceeding 20,000 to 50,000 service hours.
To ensure optimum performance of CHG Bearing 618/800 Deep Groove Ball Bearings（618 / 619 SERIES） under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 800 mm bore. For the 980 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
