Find key technical answers regarding dimensions, specifications, and replacement options for this model.
Sourcing 71805 CD/P4TFTM directly from CHG Bearing eliminates intermediate brokerage markups while granting you factory-direct engineering backup, rigorous ISO-certified quality assurance, competitive volume wholesale pricing, and dependable supply chain stability for Super-precision Angular Contact Ball Bearings.
Beyond standard alloy steel, CHG Bearing can customize the 71805 CD/P4TFTM Super-precision Angular Contact Ball 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies 71805 CD/P4TFTM with a precision bore diameter (d) of 25 mm, an outside diameter (D) of 37 mm, and a nominal ring width (B) of 21 mm. This configuration yields an effective cross-sectional wall thickness of 6.0 mm and an envelope ratio (D/d) of 1.48, delivering compact rigidity for OEM machinery housings.
To extend the trouble-free lifespan of CHG Bearing 71805 CD/P4TFTM, preventive maintenance routines should monitor operating housing temperature (normally maintaining below 70°C) and conduct regular vibration FFT analysis to identify early raceway micro-pitting before unexpected line halts occur.
