171FC109655 1094.9 mm 855 mm 918 mm 665 mm Frequently Asked Questions about 171FC109655 Four-Row Cylindrical Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
When fitting 171FC109655 over a 855 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.
Model 171FC109655 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 855 mm) and steep thermal gradients between inner and outer rings.
Built for demanding industrial environments, the 171FC109655 Four-Row Cylindrical Roller Bearings by CHG Bearing boasts a dynamic load rating (Cr) of standard dynamic and a static load threshold (C0r) of standard static. The optimized internal raceway geometry balances stress distribution, mitigating edge loading even when operating under peak mechanical stresses.
Engineered according to international ISO boundary plans, CHG Bearing supplies 171FC109655 with a precision bore diameter (d) of 855 mm, an outside diameter (D) of 1094.9 mm, and a nominal ring width (B) of 665 mm. This configuration yields an effective cross-sectional wall thickness of 120.0 mm and an envelope ratio (D/d) of 1.28, delivering compact rigidity for OEM machinery housings.
