• Angular Contact Ball Bearings:

– Designed for combined axial and radial loads, especially in high-speed applications like machine tools.

• Self-Aligning Ball Bearings:

– Accommodate misalignment and are ideal for shafts prone to bending or deflection.

• Thrust Ball Bearings:

– Handle axial loads in low-speed applications, such as rotary tables and cranes.

2. Roller Bearings:

• Cylindrical Roller Bearings:

– High radial load capacity with low friction, suitable for high-speed applications.
– Common in gearboxes and electric motors.

• Tapered Roller Bearings:

– Designed to handle combined axial and radial loads.
– Widely used in automotive wheel hubs and industrial machinery.

• Spherical Roller Bearings:

– Capable of handling heavy radial loads and misalignment.
– Ideal for mining, construction, and heavy industrial applications.

• Needle Roller Bearings:

– Compact with high load-carrying capacity, suitable for automotive transmissions and compact machinery.

3. Mounted Units and Pillow Blocks:

• Bearings housed in a rigid or flexible mounting, designed for easy installation and alignment.
• Used in conveyors, agricultural equipment, and industrial systems.

4. Linear Motion Bearings:

• Facilitate smooth linear motion in precision machinery.
• Used in CNC machines, robotics, and medical devices.

5. Specialty Bearings:

• Hybrid Bearings:

– Feature ceramic rolling elements for higher speed, lower friction, and resistance to electrical arcing.

• High-Temperature Bearings:

– Designed for extreme heat applications, such as ovens and furnaces.

• Corrosion-Resistant Bearings:

– Made from stainless steel or coated with special materials for use in marine, food, and chemical environments.

• Precision Bearings:

– High-accuracy bearings for demanding applications like aerospace, robotics, and semiconductor equipment.
