NN3036K/W33 280 mm 180 mm 74 mm 255 mm Frequently Asked Questions about NN3036K/W33 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing NN3036K/W33 Double Row Cylindrical Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF NN3036K/W33, FAG NN3036K/W33, NSK NN3036K/W33. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
When fitting NN3036K/W33 over a 180 mm shaft, CHG Bearing strictly recommends uniform induction heating (controlled between 90°C and 110°C) or precision hydraulic press sleeves. Under no circumstances should direct impact blows be struck against the rings or cage, as shock loads cause brinelling indents and premature spalling.
For international ocean and air freight, CHG Bearing packs NN3036K/W33 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for NN3036K/W33, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
