4T-JH415647/JH415610 Matched Tapered Roller Bearing 76.2x130.175x33.335mm Truck Axle Wheel Bearing

1. Product Overview

4T-JH415647/JH415610 is complete matched single row tapered roller bearing set, composed of inner cone JH415647 and outer cup JH415610, overall dimension 76.2×130.175×33.335mm. Tapered roller and conical raceway structure supports large radial load plus one-way axial load simultaneously, excellent resistance to impact and alternating shock loads during vehicle driving. Separable cone & cup design simplifies wheel hub installation, disassembly and daily maintenance. Optimized roller logarithmic profile reduces edge stress and heat generation under continuous heavy load. Widely used on heavy truck front/rear wheel hubs, semi-trailer axles, large bus drive axles and construction machinery wheel transmission assemblies.

3. Core Advantages

• Factory pre-matched JH415647 cone & JH415610 cup set, no manual pairing needed for direct installation
• Tapered roller structure bears heavy radial and unidirectional axial combined load, stable for heavy truck hub operation
• Separable inner and outer ring design, convenient on-site replacement during vehicle maintenance
• Optimized roller surface profile lowers friction heat, extends service life under long-distance heavy haul
• Standard interchange inch metric hybrid dimension, cross compatible with mainstream commercial vehicle hub spare parts
• Open structure supports supplementary lubrication to flush metal debris and reduce wear
• Custom C3 clearance, high-temperature chassis grease and outer ring laser marking services available

4. Application Scenarios

• Commercial vehicle transport: Heavy truck front & rear wheel hubs, semi-trailer axles, passenger bus wheel assemblies
• Construction machinery: Loader wheel hubs, road roller walking transmission shafts
• Agricultural heavy equipment: Large tractor drive axles, grain transport truck wheel parts

Fit OEM assembly and aftermarket replacement of heavy-load wheel hub and axle rotating equipment.
