3806/625P5 815 mm 625 mm 480 mm Frequently Asked Questions about 3806/625P5 Four-Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Model 3806/625P5 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 625 mm) and steep thermal gradients between inner and outer rings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 3806/625P5 with a precision bore diameter (d) of 625 mm, an outside diameter (D) of 815 mm, and a nominal ring width (B) of 480 mm. This configuration yields an effective cross-sectional wall thickness of 95.0 mm and an envelope ratio (D/d) of 1.3, delivering compact rigidity for OEM machinery housings.
The Open Type engineered for 3806/625P5 by CHG Bearing utilizes precision non-contact metal shields or reinforced NBR/FKM contact lip seals. This barrier prevents particulate ingress, washdown fluids, and abrasive dust from reaching the raceways while eliminating grease leakage under centrifugal forces.
Every production batch of CHG Bearing 3806/625P5 Four-Row Tapered Roller Bearings comes with complete traceability. Upon shipment, CHG Bearing can provide EN 10204 3.1 Material Test Reports (MTR), Certificates of Conformity (CoC), spectral chemical composition analysis, and dimensional inspection sheets.
