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 outer rings of theGEN 1 roller type, and the inner ring of the GEN 2 roller type. 2 Cage materialCages are made of polyamide resin reinforced with fiberglass,except the roller type for use in high temperatureenvironments, which is made of cold rolled steel.

4. LubricationThe objective of lubricating bearings is to form a film of oil onrolling or sliding surfaces to prevent the metals from makingdirect contact with each other. Lubrication has the followingeffects:

  • (1) Reduces friction and wear.
  • (2) Extends bearing life.
  • (3) Prevents rusting.
  • (4) Prevents penetration of foreign matter.

Fretting wear particularly tends to occur on the raceway of hubbearings during transport of finished automobiles. Frettingresistance must therefore be taken into account for hubbearings.

Grease is used for hub bearings because it is economical,easy to use, and it facilitates design of sealed equipment.5. Seals Hub bearing seals prevent water ingress and have low torque.


6. Orbital forming Nuts were used to fasten the inner ring of the GEN 3 ball type,but we have recently switched to forming the end of the hubwith cold plastic working (orbital forming) to fasten the innerring. This method is more reliable than fastening with nuts. It also weighs less, costs less, and is more compact.

ISO and AnSi/ABmA, as used in this publication, refer tothe international Organization for Standardization and theAmerican national Standards institute/American Bearing manufacturers Association.

Be careful in selecting lubrication, however, since differentlubricants are often incompatible.when you receive a bearing shipment, do not remove productsfrom their packaging until they are ready for mounting so theydo not become corroded or contaminated.Store bearings and bearing housings in an appropriateatmosphere so they remain protected for the intended period.
