Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Quality starts with raw material selection: CHG Bearing crafts NN3026 inner and outer rings from high-purity High-Quality Chrome Steel (GCr15/100Cr6). Our raw billets undergo vacuum degassing and secondary ESR (electroslag remelting) processes to drastically eliminate non-metallic sulfide and oxide inclusions, elevating subsurface contact fatigue resistance.
Each NN3026 produced in CHG Bearing manufacturing facilities features accurately profiled corner chamfers complying with DIN 5412 / ISO standard corner radii. When designing mating shafts and housing shoulders, machining an undercut or fillet radius strictly within the inner ring clearance limit (130 mm bore side) ensures perfect planar contact without edge binding.
In its sealed configuration (Open Type), CHG Bearing pre-charges NN3026 with premium wide-temperature lithium-complex or polyurea grease, calibrated to a 30%–35% cavity volume ratio. For open-type variants, synthetic PAO or refined mineral lubricating oils with appropriate EP (Extreme Pressure) additives should be circulated.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NN3026. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
