22318CC/W33 Spherical Roller Bearing

⚙️Definition and Structure:

Self-aligning roller bearings are bearings in which cylindrical rollers are assembled between an inner ring with two raceways and an outer ring with a spherical raceway. They feature double rows of rollers, with the inner ring having two raceways that are inclined at an angle relative to the bearing's axis. The outer ring has a single common spherical raceway. This ingenious design endows it with self-aligning properties. The center of the outer ring raceway surface aligns with the bearing center, allowing it to function properly even when there is an angular error between the shaft and the bearing housing or when the shaft is bent.

⚙️Inner hole types:

The inner holes of self-aligning roller bearings come in two types: cylindrical and tapered. The tapered inner holes are further divided into two types with tapers of 1:30 and 1:12. The taper of 1:12 is denoted by the suffix K, and the taper of 1:30 is denoted by the suffix K30. When the tapered hole self-aligning roller bearings with the suffixes K and K30 are installed on the matching tight fit sleeves, they become the types with the suffixes K + H and K30 + H, respectively, which are suitable for applications where the bearings need to be frequently installed and disassembled. To enhance the lubrication performance of the bearings, three evenly distributed oil holes are drilled in the outer ring of the bearings, and a circumferential oil groove is machined. The suffix for this type is W33.

⚙️Features and advantages:

1. High load-bearing capacity.

2. Good self-aligning performance.

3. Suitable for high-speed operation.

4. Adaptability to complex working conditions.

⚙️Main applications: Paper-making machinery, deceleration devices, railway vehicle axles, gearboxes for steel rolling machines and bearing housings, steel rolling machine rollers, crushers, vibrating screens, printing machinery, woodworking machinery, various industrial reducers, vertical bearing-mounted self-aligning bearings.

1. Keep clean	2. Use with caution	3. appropriate tool	4. Hot-loading	5. Be careful of rust
Dust will have a bad effect on the bearing, so keep the surrounding clean.	Strong impact during use can easily cause scratches and indentations.	Avoid replacing existing tools, and use appropriate tools.	Bearings are precision parts, so hot installation is recommended.	Sweat on your hands during operation will cause rust, so it is best to wear gloves.
