TR306217 Single Row Tapered Roller Bearing 30×62×17mm Automobile Gearbox Transmission Bearing

1. Product Overview

TR306217 is standard single row metric tapered roller bearing with boundary dimension d30×D62×T17mm, widely applied in automobile gearbox, differential, motorcycle power transmission and light engineering machinery reduction box.

This bearing consists of separable inner cone with rollers and outer cup, capable of bearing combined heavy radial load and one-way axial thrust load. All inner ring, outer ring and tapered rollers adopt fully quenched high-purity GCr15 bearing steel, ultra-precision superfinished raceway and roller surface to reduce contact friction and heat generation under continuous variable speed operation. The optimized roller crown modification design avoids edge stress concentration during heavy load, greatly improving anti-fatigue and anti-peeling performance. Compact thickness 17mm design saves internal installation space of transmission assemblies. It can be used alone or paired back-to-back / face-to-face to withstand bidirectional axial force, pre-filled anti-shear extreme pressure lubricating grease, stable performance under frequent vehicle start, shift and climbing load conditions.

3. Core Advantages

• Standard TR306217 unified metric size, fully interchangeable with global same specification tapered roller bearings, no modification to gearbox shaft and housing during aftermarket replacement.
• Separable cone & cup split structure, convenient independent press-fit assembly of shaft and housing, simplify production line assembly and later maintenance disassembly.
• Crown modified tapered roller design, uniform stress distribution on contact surface, effectively prevent local indentation and surface peeling under heavy impact load of automobile transmission.
• High hardness quenched bearing steel up to HRC60–65, excellent wear resistance, extend overhaul cycle of vehicle gearbox and differential components.
• Low friction superfinished raceway, less heat accumulation during high-speed rotation, reduce risk of bearing ablation caused by long-time heavy load driving.
• Stamped steel cage with stable positioning for each roller, avoid roller skew and scattering under frequent forward-reverse alternating rotation of shifting gears.
• Can be combined in pairs to realize bidirectional axial load bearing, flexible layout to meet various transmission axial positioning requirements.
• Comprehensive customized service: P6 high precision upgrade, OEM laser marking on outer cup surface, neutral export carton anti-rust packaging, high temperature transmission extreme pressure grease pre-filling.
