Precision Parts LM11949 Tapered Roller Bearing Cone ID Bearings & Seals - 3/4

The Precision Parts LM11949 is a single-row tapered roller bearing cone designed for reliable performance in automotive, trailer, and light industrial applications. With a 3/4" (0.750") inner diameter, this bearing is a widely used industry-standard fitment commonly found on 2,000 lb to 3,000 lb trailer axles, wheel hubs, and steering knuckles.

Key Features:

• Bearing Type: Single-row tapered roller bearing cone (TS type)
• Inner Diameter (Bore): 0.750" (3/4")
• Outer Diameter: 1.781"
• Cone Width (Through Bore): 0.655"
• Combined Assembly Width: 0.610"
• Tapered geometry efficiently handles both radial and axial loads simultaneously
• Precision-machined to tight tolerances for smooth, low-friction operation
• Designed to pair with matching cup/race LM11910
• Meets or exceeds OE specifications for direct replacement confidence
• Suitable for high-speed trailer wheel, automotive, and light industrial use

The LM11949 is an industry-standard tapered cone bearing used across a broad range of applications including trailer wheel hubs, automotive steering knuckles, and general industrial machinery. It must be paired with its corresponding cup (race) number LM11910 to complete the bearing assembly. The tapered roller design allows it to simultaneously carry both radial (side) and thrust (axial) loads, making it well-suited for wheel-end applications where dual-direction load support is critical.
