Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Every production batch of CHG Bearing 294/630 Spherical Roller Thrust Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
To ensure optimum performance of CHG Bearing 294/630 Spherical Roller Thrust Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 630 mm bore. For the 830 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 294/630 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.
Beyond standard alloy steel, CHG Bearing can customize the 294/630 Spherical Roller Thrust Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
