NN3134/P5 280 mm 170 mm 88 mm 251 mm Frequently Asked Questions about NN3134/P5 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing NN3134/P5 Double Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NN3134/P5, FAG NN3134/P5, NSK NN3134/P5. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
To ensure optimum performance of CHG Bearing NN3134/P5 Double Row Cylindrical Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 170 mm bore. For the 280 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Each NN3134/P5 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 (170 mm bore side) ensures perfect planar contact without edge binding.
Quality starts with raw material selection: CHG Bearing crafts NN3134/P5 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.
