Description:

1. Selection overview
Hub bearings are very important part in terms of vehicle safety. Selecting the type of bearing most suited
to the vehicle ensures safety and is very important for exhibiting the required performance. To select the
best bearing, one must consider and evaluate the bearings from a variety of angles. The procedure for
selecting hub bearings is provided in the form of a flowchart.

2. Life calculation
Life of hub bearings is calculated by inputting reaction force (radial load and axial load) 

on the wheel given as set traveling conditions as load. 

Each bearing is a "unit bearing" consisting of two rows of bearings. 

Life of the bearings is calculated separately for the each of the bearings. 

Bearing life is calculated for the outer and inner bearings. 

The shorter of the calculated values is considered the calculated life of hub bearings.

3. Hub bearing materials1 Raceway and rolling element materialsInnovations in steel manufacturing technologies such asvacuum gas removal, out-of-furnace smelting and continuouscasting have notably reduced harmful non-metallic inclusion,thus realizing longer bearing life.

CX selects quality materialsthat best suit each type of bearing.

• (1) NKJ65MBased on carbon steel, NKJ65M was developed as asubstitute for SUJ2. NKJ65M is high quality clean carbonsteel that offers lower cost and better rolling fatigue life.NKJ65M is used for the inner and outer rings of the GEN 1and inner rings of the GEN 2 and GEN 3 ball types.
• (2) SUJ2 (equivalent of SAE52100)The most commonly used material, SUJ2 is a qualitymaterial having minimal non-metallic inclusion.SUJ2 is used for balls, the inner and outer rings of the GEN1 and balls and inner rings of the GEN 2 and GEN 3 ball types.
• (3) S53C (equivalent of SAE1053)Raceways are made of induction hardened S53C, a highlyforgeable carbon steel. S53C offers superior characteristicssuch as rotational bending fatigue strength and impactresistance as well as long rolling fatigue life.S53C is used for the hub, outer ring of GEN 2 and GEN 3ball types and outer ring of GEN 2 roller type.
• (4) ET material (equivalent of SCr4435)Hardened from the surface to a suitable depth, ET materialforms a comparatively soft core. Offering a combination ofhardness and toughness, ET material is long-life casehardened steel with superior impact resistance.ET material is used for the rollers, inner and outer rings ofthe GEN 1 roller type, and the rollers and inner ring of theGEN 2 roller type.
• (5) ETA materialETA material is a long-life case hardened steel that isspecially heat-treated (carbonitriding) to enhance toughnessof the surface layer structure. It is particularly effective forsuppressing cracking caused by contaminated lubrication.ETA material is used for the rollers, inner and ou
