Why do we need spherical roller bearings?

Spherical roller bearings have double row rollers, the outer ring has a shared spherical raceway, and the inner ring has two raceways that are inclined at an angle relative to the bearing axis.

What is the disassembly method of spherical roller bearing?

The disassembly method of the seat ring of the spherical roller bearing Part of the mechanical equipment is easy to cause damage to the spherical roller bearing of the crankshaft. After the spherical roller bearing is damaged, its two sides are still stored on the side of the crankshaft hole, which is very difficult to disassemble. Since all the stainless-steel plates on both sides are relatively hard, it is easy to deviate from the direction of the hacksaw when sawing, but hitting too hard will cause damage to the crankshaft. At this time, the crankshaft cannot be fixed on the vise. According to the pullover of the heavy-duty socket wrench, the pullover on the slightly larger side of the crankshaft spherical roller bearing hole size is pressed into the crankshaft hole, and the pullover on the slightly smaller side of the crankshaft spherical roller bearing hole size is pressed in. Spherical roller bearings on both sides. After the clamping range is appropriately increased, the two sides of the spherical roller bearing are slowly pressed in.

How many important parameters do spherical roller bearings have?

1. Hardness

Hardness is one of the important qualities of spherical roller bearing, and has a direct impact on contact fatigue strength, wear resistance, and elastic limit. The hardness of bearing steel in use state generally needs to reach HRC61~65, so that the bearing can obtain higher contact fatigue strength and wear resistance.

2. Anti-rust performance

In order to prevent the parts and finished products of spherical roller bearing from being corroded and rusted during processing, storage and use, it is required that the bearing steel should have good anti-rust properties.

3. Processability

In the production process of spherical roller bearing parts, there are many cold and hot working processes. In order to meet the requirements of large batches, high efficiency and high quality, bearing steel should have good processing performance. For example, cold and hot formability, machinability, hardenability, etc.

What are the application fields of spherical roller bearings?

Spherical roller bearings are mainly used in: papermaking machinery, reduction gears, railway vehicle axles, rolling mill gearbox seats, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, self-aligning bearings with seats in general cylindrical roller bearings for generators, single row angular contact ball bearings if it is a high frequency motor.
