Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Absolutely. The CHG Bearing LY-3015 Four-Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF LY-3015, FAG LY-3015, NSK LY-3015. It shares identical envelope boundary dimensions, load capacities, and shaft fits, allowing instant drop-in replacement without retrofitting your machinery.
For international ocean and air freight, CHG Bearing packs LY-3015 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.
When fitting LY-3015 over a 340 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.
Yes, CHG Bearing works closely with industrial OEMs and brand distributors. We offer turnkey custom engineering for LY-3015, including laser-etched customer logos, custom internal radial clearances, specialized grease formulations, and bespoke protective packaging.
