Type

There are three main types of thin section bearing, or called slim bearings. Thin section tapered roller bearings, Thin section radial contact ball bearing, thin section angular contact ball bearing, and thin section four-point contact ball bearing. The pictures on the left side show that every thin section bearings have ten different cross-sections. That includes seven open types (unsealed) and five sealed types; therefore, a slim bearing has a vast loading capacity. The sealed type is only available for thin section radial contact ball bearing and four-point contact ball bearing.

Dimensions of cross sections

The cross-sectional areas range are between 0.1875" x 0.1875" to 1" x 1".  with an inner diameter ranging from 1 inch to 40 inches.

Thin section bearings selection

The most important thing for end-users to consider is the space requirements within the family of slim bearings. And the next thing a designer needs to consider is working conditions. The radial contact ball bearing mainly supports radial, double-direction axial, and combined loads. The angular contact ball bearing supports radial loads and single-direction axial loads. The four-point contact ball bearing supports radial loads, double-direction axial loads, tilting moments, etc. The tapered roller bearing mainly helps radial loads and a certain amount of single-direction axial loads.

Other consideration

The other application, including operating environment, rotational performance, mounting conditions, precision level, clearance, lubricant, seals, and temperature, must be considered.

Precision Grade

Based on American Bearing Manufacturers Association (ABMA) standards, thin section bearings' grades come in five classifications: ABEC1, 3, 5, 7, and 9. The ABEC rating does not specify many critical factors. Such as load handling capabilities, ball precision, materials, raceway polishing, noise, vibration, lubricant, etc. Due to these factors, an ABEC 3 classified bearing could perform better than an ABEC 7 bearing.

Thin section bearings difference with others

In fact, with the same inner diameter, this kind of bearings has more rolling elements than the standard bearings. And the contact areas between balls and raceway decrease, and they are also susceptible to the rigidity of bearing housing. Therefore, the slim bearing has strict requirements for housing rigidity and tolerance. We need to apply preload to control the bending and increase the linear rigidity for a specific loading capacity.  US HG Tech Corp can meet the application requirements with a unique bearing design tailored explicitly for optimum performance
