What are the dimensions of this SKF tapered roller bearing?

This bearing has an inside diameter of 20 mm, an outside diameter of 52 mm, and a total width of 16.25 mm.

What types of loads can this single-row tapered roller bearing handle?

It is designed for combined loads, supporting heavy radial forces and axial forces in one direction simultaneously.

Are the inner and outer rings separable?

Yes, the outer ring (cup) and inner ring assembly (cone) are separable for easy mounting and maintenance.

What do the suffixes J2 and Q indicate in the part number?

J2 indicates a pressed steel window-type cage, while Q denotes SKF optimized internal geometry and surface finish.

Is this SKF tapered roller bearing sealed and pre-greased?

No, this bearing has an open design and must be lubricated with appropriate grease or oil during installation.

Robust load support with Skf bearings

Practical benefits

Superior combined load capacity: You reliably accommodate simultaneous radial and axial loads thanks to the single-row tapered design with an 11.3° contact angle.
Quick and separable mounting: The inner ring assembly and outer cup separate completely, allowing you to install, inspect, and maintain the unit with ease.
Low friction smooth running: Optimized raceway geometry reduces internal friction and heat generation, helping you maintain consistent performance in demanding machinery.

In a nutshell

The right choise for

With the Skf 30304 J2/Q single-row tapered roller bearing, you ensure dependable power transmission under demanding conditions. Measuring 20 x 52 x 16.25 mm with an 11.3° contact angle, this bearing reliably accommodates simultaneous heavy radial and axial loads. The optimized raceway geometry minimizes friction and operating heat, keeping your machinery running smoothly. Because the inner and outer rings are separable, you can install and maintain the unit effortlessly in wheel hubs, industrial gearboxes, or agricultural equipment, preventing premature wear and maximizing uptime.

Product description

Single row tapered roller bearings are designed to accommodate combined radial and axial loads and provide low friction during operation. The inner ring, with rollers and cage, can be mounted separately from the outer ring. These separable and interchangeable components facilitate mounting, dismounting and maintenance. By mounting one single row tapered roller bearing against another and applying a preload, a rigid bearing application can be achieved.

Avantages

High radial and axial load carrying capacity
Accommodate axial loads in one direction
Low friction and long service life
Separable and interchangeable components
