There are several types of roller bearings, each designed to address different load requirements and applications. Here are some common types of roller bearings:

Cylindrical Roller Bearings: These bearings use cylindrical rollers and are designed to support radial loads. They can accommodate high speeds and are ideal for heavy-duty applications.

Spherical Roller Bearings: Featuring two rows of symmetrical spherical rollers, these bearings can accommodate both radial and axial loads in any direction. They are self-aligning and suitable for misaligned shafts.

Tapered Roller Bearings: These bearings have tapered inner and outer raceways, allowing them to support both radial and axial loads. They are often used in applications such as automotive wheel hubs and gearboxes.

Crossed Roller Bearings: These bearings consist of cylindrical rollers that are arranged in a crossed pattern. They can handle high axial and radial loads and provide high rigidity, making them suitable for precision machinery.

Thrust Roller Bearings: These are designed specifically to accommodate axial loads and are often used in applications such as screw drives and thrust washers.

Features of roller bearings:

Higher load capacity of roller bearings: Roller bearings use the line contact of rollers to withstand greater loads than ball bearings, especially axial loads.

Good stability: Maintain good operating stability under high load conditions.

Lower friction: Rolling friction is less than sliding friction, reducing energy loss.

Various forms: including cylindrical rollers, tapered rollers and spherical rollers, etc., to meet different application requirements.

Application industries of roller bearings:

Heavy industry: widely used in high-load occasions such as mining equipment, metallurgical equipment, heavy machinery, etc.

Engineering machinery: used for mechanical equipment such as excavators, cranes, tractors, etc.

Wind energy industry: used for the main shaft and gearbox of wind turbines.

Railway transportation: used for locomotives, vehicle axles and bogies and other components.
