32210 JR Metric Tapered Roller Bearing 50x90x24.75mm Separate Cone Cup Auto Machinery Bearing

1. Product Overview

32210 JR is single row metric separable tapered roller bearing, dimensions 50×90×24.75mm. JR optimized roller profile reduces edge stress and heat generation. Separable cone and cup structure facilitates installation and parts replacement. It bears heavy radial load and one-way axial thrust, commonly applied to truck hubs, tractor drive shafts and engineering reducers.

2. Technical Specifications

Drawings and durability test reports available on request.

3. Core Advantages

• Separable cone and cup, no full shaft disassembly during maintenance
• JR crowned rollers realize uniform stress distribution to extend service life
• Excellent composite load capacity for vehicle wheel and transmission positions
• High-strength stamped steel cage stable under shock and continuous vibration
• Superfinished raceways lower operating temperature to prevent bearing burnout
• Standard metric dimension, fully interchangeable with mainstream brand bearings
• Custom clearance, high-temperature grease and outer ring laser marking available

4. Application Scenarios

• Light & medium truck wheel hubs and differential assemblies
• Agricultural tractor transmission and harvester gearboxes
• Mini construction loaders and engineering auxiliary reducers
• Industrial conveyors and agricultural processing equipment

Suitable for OEM assembly and aftermarket replacement of mobile machinery under composite radial and axial loads.
