46T30328JR/115.5 300 mm 140 mm Frequently Asked Questions about 46T30328JR/115.5 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To ensure optimum performance of CHG Bearing 46T30328JR/115.5 Double Row Tapered Roller Bearings under general rotational loads, our application engineers advise an inner-ring shaft tolerance of m5 or k5 for the 140 mm bore. For the 300 mm outer ring, an H7 or J7 housing bore fit is recommended to eliminate creep while accommodating normal thermal gradient expansion.
Absolutely. The CHG Bearing 46T30328JR/115.5 Double Row Tapered Roller Bearings is a 1:1 direct interchange for renowned brands, matching part numbers: SKF 46T30328JR/115.5, FAG 46T30328JR/115.5, NSK 46T30328JR/115.5. 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 46T30328JR/115.5 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 46T30328JR/115.5 over a 140 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.
