JLM104948/JLM104910 Inch Tapered Roller Bearing 41.275x76.2x24.608mm Cone Cup

1. Product Overview

JLM104948/JLM104910 is single row inch standard separable tapered roller bearing set, composed of inner cone JLM104948 and outer cup JLM104910. Overall dimensions: 41.275mm bore × 76.2mm outer diameter × 24.608mm total width.
This bearing structure can withstand heavy radial load and unidirectional axial thrust load simultaneously. The separable cone and cup design allows flexible preload adjustment during assembly to match different equipment clearance and rigidity demands. All rolling components are made of fully quenched GCr15 bearing steel with precision ground tapered raceways and rollers to ensure uniform stress distribution under shock and vibration. Widely applied to light and medium truck wheel hubs, agricultural machinery drive axles, small construction equipment, heavy duty gear reducers and general off-road machinery with combined radial-axial load requirements.

2. Technical Specifications

Mounting dimension drawings, preload operation guides and load performance test reports can be provided on customer demand.

3. Core Advantages

• Separable cone and cup assembly, easy disassembly, installation and on-site preload adjustment, reducing equipment maintenance difficulty.
• Strong combined load bearing capacity, stable operation under heavy radial load and unidirectional axial thrust, excellent shock resistance for vehicle and agricultural equipment.
• Ultra-precision grinding process for raceways and tapered rollers, smooth contact surface, low running noise and long service life under cyclic impact load.
• High hardness fully quenched GCr15 steel, outstanding wear resistance and contact fatigue resistance, effectively avoiding early raceway peeling and roller damage.
• Reinforced stamped steel cage, firmly fix each roller position, prevent roller deflection under large vibration and impact conditions.
• Standard inch interchangeable size, fully compatible with global same model bearing sets, direct replacement without modifying housing and shaft structure.
• Strict taper angle tolerance control, stable contact area after installation, effectively avoid local overheating and abnormal wear.
• Multiple customizable options: P0/P6 precision grade, anti-rust surface coating, OEM laser marking on cone and cup, neutral export anti-rust carton packaging, high temperature resistant special grease filling.
