Miniature Bearings

Miniature bearings refer to ball bearings with small sizes. The following list shows the data of ball bearings whose inner diameters are less than 10mm. If you need a product with its inner diameter over 10mm, please visit the page of deep groove ball bearings. This miniature bearing catalog provides detailed specifications for each type, including outer diameter, width, load capacity, and operational speed limits. Whether you're looking for bearings for precision instruments, miniature motors, or other compact applications, our selection ensures you find the perfect fit for your project.

Thin Section Bearings

Thin Section Bearings as listed below are available open, shielded or sealed. Available in a variety of standard and custom inch and metric sizes, our thin section bearings offer high performance in corrosive and non-corrosive environments where space devoted to bearings is at a minimum.

Angular Contact Ball Bearings

Angular contact ball bearings support both radial and axial loads through asymmetric races that house the bearing’s spherical rolling elements, also called bearing balls, on an angle. The deeper the angle between the bearing and its axis, the greater the axial load the bearing can carry. Because the contact angle provides stability and load-carrying capacity in both radial and axial directions, angular contact ball bearings are commonly used in applications requiring high precision and stiffness, such as machine tool spindles, electric motors, and automotive transmissions.

Flanged Ball Bearings

Flanged bearings feature a solid steel flange on their outer ring, making it simpler to position them within a housing. The flange further aids in preventing axial movement of the bearing if it experiences a thrust load. Maintaining the position of a flanged bearing in a fixed or mounted assembly is more straightforward. Moreover, the flange adds extra stability and rigidity to the bearing system, guaranteeing its ability to endure heavier loads and sustain precise operation over an extended period. The flange's design also enhances the ease of installing and removing the bearing, as it can be used as a point of reference for alignment during the assembly process.

Deep Groove Ball Bearings

Deep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, and accommodate radial and axial loads in both directions. Single-row deep groove ball bearings are available in open and sealed designs. Double-row deep groove ball bearings correspond with single-row bearings in terms of load capacity and speed capacity, but they can accommodate axial loads acting in one direction only and must therefore be mounted in pairs to balance axial forces.

Thrust Ball Bearings

Thrust ball bearings are separable bearings. The single-acting thrust ball bearing consists of a shaft washer, a housing washer, and a ball set with cage. The double-acting type consists of a shaft washer (centre washer), two housing washers, and two ball sets with cages. Thrust ball bearings can be a valuable solution for applications requiring pure axial loads or combined axial and radial loads, where radial loads are relatively small. The separable design allows for easier installation and removal, as well as maintenance and inspection, without the need to dismantle adjacent machine components. This makes thrust ball bearings particularly suitable for applications where frequent adjustments or replacements are necessary.

Self Aligning Ball Bearings

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused by shaft deflection or misalignment of the bearing seats. This feature allows self-aligning ball bearings to operate reliably in applications where shaft misalignment is unavoidable, such as in machinery with flexible shafts or where the bearing seats are not perfectly aligned. Additionally, their ability to handle radial and axial loads in both directions makes them versatile for a wide range of applications.

Mast Guide Bearings

Mast Guide bearings are used for high radial and occaisonal thrust loads. They typically have a thick cross section on the outer race which performs as a wheel or tire.
