Axial Spherical Roller B. SKF 29456 E

The SKF 29456 E axial self-aligning roller bearing, measuring 280 x 520 x 145 mm, accommodates heavy axial loads and compensates for misalignment.

This single-row axial self-aligning roller bearing 29456 E is designed for heavy mechanical loads in continuous industrial operation. Thanks to the spherical shape of the housing raceway, the bearing adjusts to angular movement, thereby compensating for shaft deflection. As an SKF Explorer version, the bearing is made from standard rolling-element steel (100Cr6) and operates within a temperature range of -30 to +200 degrees.

What is the 29456 E axial self-aligning roller bearing suitable for?

Design engineers primarily use this roller bearing in industrial plant where axial forces acting in a single direction predominate. Typical applications include bearing arrangements subject to high axial thrust loads and misalignment. In addition to purely longitudinal forces, the bearing can also accommodate radial load components. Thanks to its angularly adjustable design, the component counteracts edge pressures should the shaft deform elastically under load or should housing misalignments occur during assembly.

What are the key features of the version with a sheet steel cage?

The integrated sheet steel cage guides the barrel-shaped rollers reliably even at high temperatures and is resistant to lubricants. As this single-acting bearing is not self-retaining, fit the shaft and housing washers separately. Ensure that the tolerance class P0/PN (ABEC 1) is maintained on the mating surfaces. During operation, the component requires a defined minimum axial load to prevent slippage between the rolling elements and the raceways.

What are the key features of the 29456 E axial self-aligning roller bearing?

This roller bearing withstands very high axial loads in one direction whilst simultaneously compensating for both static and dynamic shaft misalignment. SKF’s Explorer version is optimised for demanding industrial applications and can withstand operating temperatures ranging from -30 to +200 degrees.

What are the dimensions of bearing 29456 E?

The bearing has an internal diameter of 280 mm at the shaft flange. The external diameter is 520 mm, whilst the overall height is 145 mm. These key dimensions determine the required installation space within the housing and the bearing seat on the shaft.

Can radial forces also be transmitted using the 29456 E axial self-aligning roller bearing?

Yes, because the rollers are arranged at an angle to the axis of rotation, the component transmits radial loads as well as the primary axial forces. It is important that the axial load always predominates, so that the rollers make positive contact with the guide flanges and the discs are prevented from lifting off.

What is the purpose of the sheet steel cage?

The cage, made of pressed sheet steel, keeps the roller elements at a uniform distance apart and controls their rolling motion. It is highly robust whilst being lightweight. This makes the design suitable for both lubricating oil and grease, and ensures stable operation across the full temperature range.

What does the tolerance class P0/PN mean?

Tolerance class P0 (equivalent to PN or ABEC 1) defines the standard accuracy for dimensional and running error tolerances in accordance with international standards. It ensures dimensionally accurate mounting on industrial shafts and in standard housings, without the need for excessively tight manufacturing tolerances on the mating parts.

Why is a minimum load required during operation?

Axial-thrust roller bearings require a constant minimum axial load during operation. This load helps to ensure that the rolling elements roll along the raceways without slippage. Insufficient contact pressure can cause sliding movements, which unnecessarily increase friction and damage the raceway material.
