EE148122/148221XD 558.8 mm 311.15 mm Frequently Asked Questions about EE148122/148221XD Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model EE148122/148221XD is manufactured by CHG Bearing in standard Normal clearance (CN) for ambient temperature transmission, and C3 or C4 clearance for heavy duty applications. C3 clearance compensates for radial shrinkage caused by tight shaft press-fits (bore 311.15 mm) and steep thermal gradients between inner and outer rings.
For international ocean and air freight, CHG Bearing packs EE148122/148221XD 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.
