32218 JR Metric Tapered Roller Bearing 90x160x42.5mm Separable Cone Cup Heavy Truck Axle Bearing

1. Product Overview

32218 JR is single row metric separable tapered roller bearing with dimension 90×160×42.5mm. JR logarithmic crowned rollers reduce edge stress and frictional heat. Separable cone and cup design facilitates disassembly, inspection and replacement without full shaft removal. It carries heavy combined radial and one-way axial thrust loads, commonly fitted to heavy truck axles, large tractor transmission and mining machinery reducers.

2. Technical Specifications

Dimension drawings and durability test reports available on request.

3. Core Advantages

• Separable cone and cup for easy maintenance and part replacement
• JR optimized crowned rollers realize even load distribution and extend service life
• Super high composite load capacity for heavy vehicle axle and transmission positions
• Reinforced stamped steel cage keeps stable operation under severe vibration and impact
• Ultra-smooth superfinished raceways lower running temperature to avoid bearing burnout
• Standard metric size, fully interchangeable with mainstream brand bearings
• Custom clearance, high-temperature grease and outer ring laser marking services available

4. Application Scenarios

• Heavy duty truck rear axles and differential assemblies
• Large agricultural tractor drive shafts and harvester gearboxes
• Mining transport vehicle wheel hubs and heavy load conveyors
• Medium construction machinery loader hubs and industrial reducers

Fit OEM assembly and aftermarket replacement of heavy machinery under large composite loads.
