Tapered Roller Bearing:1097784

Description

Basic Parameters

The tapered roller bearing 1097784 has an inner diameter of 80mm, an outer diameter of 140mm, and an overall width of 33mm, with a basic dynamic load rating of 145kN and a basic static load rating of 190kN, capable of withstanding combined radial and axial loads; under grease lubrication, its limiting speed is 3200r/min, and the weight per bearing is 2.15kg; the main body of the bearing is made of GCr15 bearing steel, with a precision class of P6, and the default seal type is open structure, while double-sided contact seal can also be selected according to requirements to adapt to different protection scenarios.

Product Features

High Load-Bearing Capacity：Adopts a tapered roller structure design, capable of withstanding large radial and axial loads simultaneously. With a basic dynamic load rating of 145kN, it is suitable for the transmission needs of medium and heavy-duty equipment, with excellent impact resistance.

Wear Resistance & Durability：The main body is made of GCr15 high-purity bearing steel, processed through precision heat treatment such as quenching and tempering. The hardness is stably maintained at HRC58-62, and the surface roughness is as low as Ra0.4μm, which effectively reduces friction loss and extends service life (8000-12000 hours under normal working conditions).

Precise & Stable Operation：Manufactured to P6 class precision, the coaxiality error between the inner and outer rings is ≤0.015mm. The rollers and raceways have high fit accuracy, with a vibration velocity of ≤6.3mm/s and noise controlled below 65dB during operation, ensuring stable equipment operation.

Flexible Adaptability：Supports two types of structures: open type and double-sided contact seal. The open type is suitable for high-temperature and high-speed scenarios (e.g., industrial gearboxes), while the sealed type can prevent dust and oil contamination (e.g., construction machinery wheel hubs), meeting different working condition requirements.

Easy Installation & Maintenance：The inner ring can be separated from the roller assembly. During installation, there is no need to disassemble the entire equipment; only the inner or outer ring needs to be assembled separately, reducing maintenance difficulty and saving downtime.

 

Application Fields

Construction Machinery Field：Suitable for the travel mechanism of 3-5 ton excavators and the slewing bearing part of loaders. With high load-bearing and impact resistance, it can withstand frequent load changes during equipment operation and ensure the stability of the transmission system.

Heavy-Duty Vehicle Field：Used in the drive axle and wheel hub bearing unit of heavy-duty trucks (load capacity ≥15 tons). It can withstand radial pressure and axial thrust during long-term high-speed driving, reduce hub heat generation, and lower failure rates.

Industrial Transmission Equipment Field：Applicable to the main shaft transmission of reducers (e.g., mining reducers, chemical mixing reducers) and winches. The P6 class precision and low vibration characteristics can improve transmission efficiency and avoid equipment jamming caused by bearing errors.

Mining Machinery Field：Matched with the rotor shaft of small and medium-sized crushers and the roller bearing of belt conveyors. The wear resistance of GCr15 steel can cope with the harsh working conditions of high dust and large load in mines, extending the equipment maintenance cycle.

Agricultural Machinery Field：Used in the travel gearbox of large combine harvesters and the drive axle of tractors. The open structure is suitable for the high-temperature working environment of agricultural machinery, and the optional sealed solution can cope with muddy field scenarios, improving adaptability.
