HM252349D/HM252315 431.724 mm 260.35 mm Frequently Asked Questions about HM252349D/HM252315 Double Row Tapered Roller Bearings
Find key technical answers regarding dimensions, specifications, and replacement options for this model.
To match diverse operational dynamics, CHG Bearing supplies HM252349D/HM252315 with multiple cage configurations: high-strength pressed steel ribbon cages for standard duty, solid machined brass cages (M/CA) for heavy vibration and shock loads, or lightweight glass-fiber reinforced polyamide cages (TN9/TVP) for high acceleration and ultra-low noise.
To extend the trouble-free lifespan of CHG Bearing HM252349D/HM252315, 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.
Engineered according to international ISO boundary plans, CHG Bearing supplies HM252349D/HM252315 with a precision bore diameter (d) of 260.35 mm, an outside diameter (D) of 431.724 mm, and a nominal ring width (B) of 148.433 mm. This configuration yields an effective cross-sectional wall thickness of 85.7 mm and an envelope ratio (D/d) of 1.66, delivering compact rigidity for OEM machinery housings.
Every production batch of CHG Bearing HM252349D/HM252315 Double 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.
