High Precision Miniature Bearings
Deep Groove Ball Bearings (
)

- Deep groove ball bearings are versatile, self-retaining bearings with solid outer rings, inner rings and ball and cage assemblies
- These products are of simple design, durable in operation and easy to maintain; they are available in single and double row designs and and in open and sealed variants
- Due to the production technology used, open bearings can still have turned recesses on the outer ring for seals or shields

Spherical Roller Bearings (
)
- Self-aligning bearings designed for heavy radial loading. They automatically compensate for large angular errors (shaft misalignments)
- Small Type C bearings are widely applicable for small size machines and are suited for both radial and axial loads
- Standard Type B bearings provide ideal contact pressure under radial or combined radial and axial loads, and perform well under high speeds
- Type UA bearings are designed to provide increased life and are ideally suited for heavy, shock or vibratory types of radial loading (i.e. Shaker screens).

Electrical Motor Bearings (
)
- Special consideration has been given to quietness, internal tolerances, lubrication, seals and shields
- Various lubricants are available that will operate over a wide temperature range
- Several tolerance grades are available to meet the specific motor requirements
- Bearings are available with contact or non-contact seals or shields
