Precision Parts LM29749 Tapered Roller Bearing Cone Bore Bearings & Seals - 1.5

The Precision Parts LM29749 is a single-row tapered roller bearing cone in the imperial series, designed to handle combined radial and axial (thrust) loads with precision and reliability. This is the cone (inner ring assembly) component of the LM29749/LM29710 bearing set, featuring a 1.5-inch bore and engineered for use in trailer axles, wheel hubs, automotive applications, and a wide range of industrial machinery.

Key Features:

• Type: Single-row tapered roller bearing cone (TS — Tapered Single, Imperial)
• Bore (Inner Diameter): 1.500 in (38.1 mm)
• Outer Diameter: 2.5625 in (65.09 mm)
• Width: 0.72 in (18.3 mm)
• Cup Width: 0.55 in
• Tapered roller design supports both radial and axial loads simultaneously
• Cone assembly consists of inner ring, tapered rollers, and cage — separable from cup (outer ring)
• Rated for trailer axle applications from 5,200 lb to 7,000 lb capacity
• Manufactured to imperial dimensional standards for direct fitment compatibility
• High-quality steel construction for fatigue resistance and long service life

The LM29749 cone is typically paired with the LM29710 cup (race) to form a complete tapered roller bearing assembly. Common applications include trailer wheel hubs, automotive wheel bearings, gearboxes, pumps, and other rotating equipment where precise load management is required. Cross-references include the assembly number LM29749-9X061.
