Model:807813  Tapered Roller Bearings

SIZE:65*150*54

Weight:4.5kg

The 807813 bearing, an imperial tapered roller bearing (commonly corresponding to standard model 30613), offers significant advantages in industrial transmission and heavy-duty machinery. Its core advantages lie in its load-bearing capacity, structural adaptability, and operational stability.

I. High Load-Bearing Capacity, Adaptable to Complex Stress Conditions: Utilizing a tapered roller design, it can simultaneously withstand large radial and axial loads, making it particularly suitable for scenarios with combined loads, such as automotive wheel hubs, gearboxes, and construction machinery drive shafts.

Optimized contact lines between the rollers and inner and outer rings result in more uniform stress distribution, improving fatigue life and reliability.

II. Mature Structure and Strong Interchangeability: Belonging to a highly standardized imperial bearing series, it is widely used in Russian-made equipment (such as LADA automobiles) and domestic replacement scenarios, with ample spare parts supply.

The mainstream dimensions of 65mm inner diameter, 150mm outer diameter, and 54mm width conform to GB/T 297-2015 standard, facilitating installation, maintenance, and batch replacement.

III. Stable Operation, Adaptable to Medium- and High-Speed Conditions

Although some sources mention a "thin-walled 807813" (outer diameter 85mm, width 13mm), its mainstream application remains heavy-duty. Its limiting speed under grease lubrication can reach 4000-5000 rpm, meeting the needs of most medium-speed transmissions.

The cage is mostly made of high-strength engineering plastics or stamped steel, ensuring smooth operation and low noise.

IV. Combining Economy and Maintainability
Due to large-scale production and numerous manufacturers, the price is relatively reasonable, and procurement is convenient.

The separable inner and outer ring design facilitates installation and clearance adjustment, which is beneficial for later maintenance and precision calibration.

It should be noted that "807813" is sometimes mistakenly labeled as a small thin-walled bearing in the market. When purchasing, the actual size and application scenario should be verified to avoid confusion.
