NNU4926P5 180 mm 130 mm 146 mm 50 mm Frequently Asked Questions about NNU4926P5 Double Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model NNU4926P5 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 130 mm) and steep thermal gradients between inner and outer rings.
For international ocean and air freight, CHG Bearing packs NNU4926P5 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.
As a primary manufacturer, CHG Bearing supports both trial batch evaluations and container-load supply for NNU4926P5. Standard catalog sizes are stocked for rapid 3–7 day dispatch, while high-volume OEM production runs typically dispatch within 30–45 days.
Beyond standard alloy steel, CHG Bearing can customize the NNU4926P5 Double Row Cylindrical Roller Bearings using AISI 440C stainless steel, black oxide coating, zinc-nickel plating, or hybrid ceramic (Si3N4) balls for applications involving chemical exposure, marine salt fog, or galvanic current hazards.
