Spherical Roller Bearings SKF 22336 CCK/W33

The SKF 22336 CCK/W33 spherical roller bearing, measuring 180 × 380 × 126 mm, offers angular adjustability, a lubrication groove and precise P5 running accuracy for heavy-duty industrial applications.

The 22336 CCK/W33 self-aligning roller bearing is a double-row roller bearing designed for demanding heavy-duty applications. Its design automatically compensates for misalignment and shaft deflection. This open bearing, made from standard 100Cr6 rolling bearing steel, features a tapered bore and a sheet steel cage. A lubrication system in the outer ring ensures even distribution of grease and oil directly in the rolling element area.

What is the 22336 CCK/W33 self-aligning roller bearing suitable for?

This self-aligning roller bearing is particularly suitable for heavily loaded industrial applications and heavy-duty bearings subjected to high radial forces. At the same time, it accommodates axial loads acting from both directions. Thanks to the spherical outer ring raceway, the bearing tolerates shaft misalignment without undulatory stresses occurring. Thanks to its permissible operating temperature range of –30 to +200 degrees, this design can also withstand significant thermal fluctuations during operation.

What are the advantages of the tapered bore with W33 lubrication groove?

The tapered bore with a 1:12 taper allows for direct mounting on tapered shaft seats or mounting on cylindrical shafts using clamping and withdrawal sleeves. During assembly, qualified personnel precisely set the desired bearing clearance by axially sliding the bearing onto the shaft. The designation W33 denotes a circumferential lubrication groove with lubrication holes in the outer ring, allowing the lubricant to be applied directly between the rows of rollers during maintenance work.
