Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing NN3134 Double Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NN3134, FAG NN3134, NSK NN3134. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
Quality starts with raw material selection: CHG Bearing crafts NN3134 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NN3134. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Engineered according to international ISO boundary plans, CHG Bearing supplies NN3134 with a precision bore diameter (d) of 170 mm, an outside diameter (D) of 280 mm, and a nominal ring width (B) of 88 mm. This configuration yields an effective cross-sectional wall thickness of 55.0 mm and an envelope ratio (D/d) of 1.65, delivering compact rigidity for OEM machinery housings.
