534565 Heavy Duty Double Row Tapered Roller Bearing Truck Wheel Hub Axle Bearing

1. Product Overview

534565 is integrated double row tapered roller bearing specially developed for heavy commercial trucks, semi-trailers and large logistics transport vehicle wheel hub axles. Adopts back-to-back double row tapered roller internal layout, capable of bearing huge combined radial load and bidirectional axial thrust generated during full-load driving, sharp turning and emergency braking.

All inner rings, outer rings and tapered rollers are manufactured from high-purity fully quenched GCr15 bearing steel, ultra-precision superfinished raceway surface effectively reduces rolling friction and heat accumulation under long-distance continuous high-speed operation. Equipped with multi-layer labyrinth composite double-sided sealing system, which can block road mud, sand, rainwater and brake dust to prevent internal grease dilution and roller rust. Pre-filled high-temperature anti-shear extreme pressure chassis grease inside the bearing, stable anti-fatigue performance under variable load and complex road conditions. Integrated compact structure simplifies axle assembly process, widely matched heavy-duty semi-trailer support axles, container truck driving axles and large cargo vehicle wheel hub rotating positions.

2. Technical Specifications

Complete trailer axle hub installation drawings, full heavy load matching selection guide and long-cycle road vibration wear durability test reports can be provided upon customer request.

3. Core Advantages

• 534565 integral double row back-to-back tapered roller design, excellent bidirectional axial rigidity, effectively restrain wheel axial offset under heavy load climbing and frequent braking.
• Multi-layer labyrinth composite sealing structure, dual barrier against mud, gravel and rainwater on mountain and muddy construction roads, greatly extend bearing service cycle of long-haul logistics vehicles.
• High purity bearing steel integral forging and overall quenching, hardness reaches HRC60–65, strong anti-indentation and contact fatigue resistance, reduce vehicle breakdown risk on highway transportation.
• Pre-filled high-temperature shear-resistant extreme pressure chassis grease, slow grease loss under uninterrupted long-distance driving, stable lubrication for all-day transport operation.
• Optimized roller crown modification and raceway geometric curve, uniform contact stress distribution, lower heat generation and avoid bearing ablation caused by overheating of heavy-load axles.
• One-piece integrated bearing unit, no complicated clearance adjustment required during axle assembly, greatly improve production line assembly efficiency.
• Standard unified hub installation dimension, fully interchangeable with global 534565 series heavy trailer wheel bearings, direct replacement without modifying axle housing and hub.
• Comprehensive customized service: P6 high precision upgrade, OEM laser marking on outer ring surface, neutral export wooden case anti-rust packaging, high temperature anti-wear chassis grease pre-filling.
