Frequently Asked Questions about 2TDI-LM281049DGW-010 Four-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 2TDI-LM281049DGW-010 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.
Sourcing 2TDI-LM281049DGW-010 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 Four-Row Tapered Roller Bearings.
Engineered according to international ISO boundary plans, CHG Bearing supplies 2TDI-LM281049DGW-010 with a precision bore diameter (d) of 646.112 mm, an outside diameter (D) of 857.25 mm, and a nominal ring width (B) of 542.925 mm. This configuration yields an effective cross-sectional wall thickness of 105.6 mm and an envelope ratio (D/d) of 1.33, delivering compact rigidity for OEM machinery housings.
Model 2TDI-LM281049DGW-010 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 646.112 mm) and steep thermal gradients between inner and outer rings.
