57.6*64.68-1 57.6 mm 64.68 mm 577 mm Frequently Asked Questions about 57.6*64.68-1 Tapered Rollers
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 57.6*64.68-1 Tapered Rollers under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the mm bore. For the mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
For international ocean and air freight, CHG Bearing packs 57.6*64.68-1 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.
To match diverse operational dynamics, CHG Bearing supplies 57.6*64.68-1 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
Standard batches of CHG Bearing 57.6*64.68-1 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.
