Tapered Roller Bearing:32005

Description

Basic Parameters

The 32005 tapered roller bearing features a single-row separable design. It has an inner diameter of 25 mm, an outer diameter of 47 mm, and a total width of 15 mm (inner ring width 15 mm, outer ring width 11.5 mm). This bearing is specifically designed to withstand combined radial and single-direction axial loads. Its dynamic load (Cr) ranges from 28 – 31 kN, and its static load (Cor) is between 32 – 34 kN, delivering excellent performance in heavy-duty applications. The limiting speeds of this bearing are 7,500 – 8,000 rpm (grease lubrication) and 9,500 – 11,000 rpm (oil lubrication). Its contact angle (10° – 17°) optimizes load distribution. The bearing weighs approximately 0.11 – 0.12 kg and uses precisely ground tapered rollers and raceways to reduce friction and wear. The standard configuration includes a separable inner ring (inner ring with rollers/cage) and an outer ring (outer ring), enabling flexible installation, as well as a steel cage to ensure stable guidance of the rollers. This bearing complies with ISO metric standards and is an ideal choice for automotive transmissions, industrial machinery, and gearboxes, offering both compact dimensions and high load-carrying capacity.

Product Application

The 32005 tapered roller bearing performs outstandingly in various mechanical systems that need to effectively handle combined radial and single – direction axial loads. It provides reliable performance for various industries by leveraging its robust design and precision engineering.

1.Automotive system

In automotive applications, this bearing is a key component of the manual transmission, used to support the rotating shaft under fluctuating torque and axial forces generated during gear shifting. Its separable design – the inner ring (with rollers/cage) and the outer ring (outer race) – facilitates easy installation and alignment within the compact transmission housing. Additionally, it is suitable for the differential assembly, capable of withstanding high-speed, high-load power distribution conditions while minimizing friction to improve fuel efficiency. The contact angle of this bearing (10° to 17°) optimizes the load distribution, making it an ideal choice for the front-wheel drive hubs of passenger cars, which can withstand the radial loads generated by the vehicle’s weight and the axial thrust generated by cornering forces.

2.Industrial Machinery and Equipment

For industrial gearboxes and conveyor systems, the 32005 bearing ensures smooth operation under heavy radial loads, such as those encountered in material handling equipment or manufacturing machinery. Its high dynamic load rating (28 – 31 kN) and static load rating (32 – 34 kN) enable it to withstand the shock loads and misalignments common in industrial environments. This bearing also operates reliably in pumps and compressors, where it supports the rotating shaft that is subjected to the axial thrust of fluid pressure as well as the radial load of mechanical vibration. Its limiting speed with grease lubrication is 7,500 – 8,000 rpm (and 9,500 – 11,000 rpm with oil lubrication), making it suitable for medium – to – high – speed applications. The steel cage maintains stable roller guidance to reduce wear and noise.

3.Agricultural and construction machinery

In agricultural equipment such as tractors, harvesters, and balers, the 32005 bearing can withstand dirt, moisture, and heavy loads in harsh conditions of the transmission system, axles, and implement linkages. Its corrosion-resistant steel structure (combined with appropriate surface treatment) and strong load capacity make it highly suitable for farming machinery, enabling it to endure the impact of uneven terrain. For construction machinery such as excavators, loaders, and cranes, this bearing is used in slewing drives, boom pivot points, and wheel hubs, providing reliable support for high-torque, low-speed operation. The separable design simplifies maintenance in remote or harsh environments, reducing downtime during inspections or replacements.
