795‑90128 Inch Tapered Roller Bearing 79.375x136.525x33.338mm Cone And Cup

1. Product Overview

795‑90128 is single‑row inch‑size tapered roller bearing assembly, composed of separable cone (inner ring with rollers & cage) and cup (outer ring). Dimensions:79.375 mm inner bore × 136.525 mm outer diameter × 33.338 mm total width.

This bearing can bear combined heavy radial load and one‑direction axial thrust load. Separate design allows mounting preload adjustment during assembly. Precision machined tapered raceway and rollers ensure even stress distribution. Adopt high‑quality GCr15 bearing steel for all rolling components. Widely used for heavy truck axle hubs, mining machinery, heavy trailer wheels, construction machinery, agricultural heavy‑duty equipment and reducer units requiring combined radial‑axial load capacity.

3. Core Advantages

• Separable cone‑cup construction, convenient installation, disassembly and pre‑load adjustment to meet different equipment clearance requirements.
• Excellent combined load capacity: withstand heavy radial load plus large unidirectional axial thrust load, ideal for wheel‑hub and heavy transmission positions.
• Precision tapered raceway and roller surface grinding, uniform contact stress, low running noise and stable performance under shock and intermittent impact load.
• GCr15 fully quenched bearing steel, good wear‑resistance and contact‑fatigue performance, long service‑life for heavy‑duty cyclic working conditions.
• Stamped steel cage with stable rigidity, keeps tapered rollers in correct position, reduces roller skew during high‑impact operation.
• Standard inch series interchangeable dimension, fully interchangeable with global 795‑90128 tapered roller bearing sets, direct replacement without housing modification.
• Strictly controlled taper angle tolerance, consistent contact pattern after mounting, avoid local over‑heating and premature wear.
• Rich custom options: P0/P6 precision grade, special anti‑corrosion coating, OEM laser marking on cone/cup, neutral export anti‑rust carton, special high‑temperature grease filling.
