This 40 x 90 x 23 mm (6308-ZZ C3) bearing is a metric deep groove ball bearing. The 6308-ZZ C3 inner diameter is 40 mm, the 6308-ZZ C3 outer diameter is 90 mm, the 6308-ZZ C3 width is 23 mm. This bearing has non-contact metal shields on both sides to protect the bearing from dust or any possible contamination, which can extend bearing life, and retain the lubricant in the bearing.

Their symmetrical design features two grooved shaft washers, two flat housing washers, and a set of balls retained by a central cage. This configuration allows bidirectional support, making them ideal for scenarios where thrust forces may act in opposing directions. These bearings find extensive use in heavy-duty industrial machinery, large-scale power transmission systems, and high-speed aerospace applications.

The bearings are not self-retaining; the ball and cage assembly and bearing washers can therefore be fitted separately. In addition to the series with flat washers, series are also available with spherical housing locating washers for the compensation of static angular misalignment. These designs are normally used in conjunction with seating washers. Common uses include automotive transmissions, electric motors, and compact industrial machinery.

Tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads. The bearings are very stiff and are a compact design being able to fit into a small axial space.

Applications for Double Direction thrust ball bearings include vacuum pumps, disc hubs in agricultural machinery, compressors, press machines, and clutch breakers.

Tapered Roller Thrust bearings are of a separable design.The shaft washer and housing washers and the roller with cages can be mounted separately.The roller end design and surface finish on the flange promote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. Depending on the design,the rollers being crowned or logarithmic raceway profiles optimize the load distribution along the contact surfaces, reducing stress peaks at the roller ends, and reducing the sensitivity to misalignment compared with conventional straight raceway profiles.

Enhanced operational reliability is due in part to the surface finish on the contact surfaces on the rollers and raceway supports in combination with the  formation of a hydrodynamic lubricant film. High load carrying capacity is possible due to the close toleranced manufacturing process.

A cage contains the balls while the grooved aligning seat washers guide them. Washers that have the shaft centered through them are called “shaft washers” and washers installed in  the housing are called “housing washers.” Single Direction thrust ball bearings can take thrust or axial loads in a single direction . Double Direction ball bearings  are bi-directional. Thrust ball bearings with aligning seat washers help reduce the effects of mounting errors.

Thrust ball bearings are sometimes referred to as axial deep groove ball bearings versus the standard radial deep groove ball bearings which accept both radial and axial loads. It is important to understand that axial and thrust loads are different words for the same concept. They both refer to loads acting parallel to the axis of the shaft. The importance of thrust ball bearing design lies in the concept of use for  axial loads only. See below the comparison of axial deep groove ball versus radial deep groove ball bearings.

The rollers incorporated in SKF tapered roller thrust bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution and enables the bearings to accommodate heavy axial loads.

Single-Direction Thrust Ball Bearings are engineered to withstand axial loads in one direction only. Their design includes a grooved shaft washer, a flat housing washer, and a set of balls captured by a cage. Variations of this design allow for two flat washers, two grooved washers or one grooved and one flat washer. Due to their simplicity and cost-effectiveness, engineers frequently employ single-direction thrust ball bearings in applications where unidirectional thrust forces are prevalent.

Сomprehensive understanding of the fundamentals, types, applications, and limitations of thrust ball bearings empowers engineers to make informed decisions and achieve optimal performance in  all kinds of applications.
