14. Capped Bearings with Seals or Dust Covers These bearings feature one or two seals, dust caps, or a combination of both. They are designed to protect internal components from contaminants while maintaining performance.

15. Pre-Lubricated Bearings Manufacturers now commonly fill these roller bearings with lubricant during production, ensuring smooth operation right out of the box.

16. Precision Instrument Bearings These are specialized rolling bearings used in precision instruments where accuracy and reliability are critical.

17. Combined Bearings These are bearings that are paired together, either as a single unit or as part of a set, to meet specific mechanical requirements.

(2) Radial Bearings

1. Radial Bearings Designed primarily for radial loads, these bearings have a nominal contact angle ranging between 0° and 45°. The main components include the inner ring, outer ring, rolling elements, and optionally a cage.

2. Radial Contact Bearings A type of radial bearing with a nominal contact angle of 0°, providing maximum load capacity in the radial direction.

3. Angular Contact Radial Bearings These bearings have a contact angle greater than 0° but less than 45°, allowing them to handle both radial and axial loads effectively.

4. Spherical Bearings Radial bearings with an outer spherical surface and a wide inner ring, often featuring locking parts. They are ideal for applications where misalignment is expected.

5. Tapered Bore Bearings These bearings have a tapered inner bore, making them suitable for use on tapered shafts or when a secure fit is required.

6. Flanged Bearings These bearings have a flange on one of their rings, typically found on radial roller bearings with an outer flange or conical outer ring.

7. Roller Bearings (Rolling Bearings) Radial bearings with a thick-walled outer ring, often used in applications like rail systems or cam tracks where high load capacity is needed.

8. Retaining Ring Type Roller Bearings (Yoke Type Track Rollers) These bearings feature a pair of flat retaining rings, providing additional support and stability in heavy-duty applications.

9. Universal Matched Bearings When selecting one or more sets of the same type of radial bearings, they can be matched to achieve pre-determined performance characteristics for pairs or groups of devices.
