SKF tapered roller bearings handle combined radial and axial loads thanks to the angled rollers and tapered raceways. They suit gearboxes, transmission shafts, and industrial machinery where forces are significant. MR Industrial Accessories supplies this line to customers across the United States, Canada, Mexico, and South America.
The code 30240 J2/DFC570 follows the usual pattern: the basic number indicates size and dimensional series, while the suffixes describe construction variants. When you request a quote, send the complete part number exactly as it appears on the drawing or the component.
These bearings appear in gear reducer housings, conveyor rollers, mill shafts, overhead cranes, and material handling equipment. Their ability to take radial and axial loads in two directions makes them a common choice in power transmission assemblies.
Selection depends on radial and axial load, rotation speed, and environmental conditions. Mounting calls for precise alignment and correct adjustment of axial clearance, usually set with lock nuts or shims. Lubrication must match temperature and speed, and sealing must keep out dust and moisture.
When comparing brands, codes from different manufacturers often share dimensions and capacities. Check interchangeability by inner diameter, outer diameter, width, and roller arrangement. If you have another brand's part number or an unidentified part, send us the data and we will suggest the compatible alternative we supply.

Frequently asked questions
- What loads can tapered roller bearings support?
- They are designed for combined radial and axial loads due to the inclined roller arrangement. This makes them suitable for applications with significant forces in two directions, such as gearboxes and transmission shafts.
- How should a tapered roller bearing be mounted?
- Mounting requires precise alignment and correct adjustment of axial clearance, which is regulated with lock nuts or shims. Choose the right lubrication and protect the assembly against dust and moisture with proper sealing.
- Can I replace a bearing from another brand with an SKF one?
- In many cases yes, as long as the main dimensions and the roller arrangement match. If you send us the original part number or dimensions, we will tell you the compatible alternative we sell.
