FAQ

Question?
What is the significance of the 'K30' suffix on the SKF 24128 CCK30/W33 bearing?
Answer:
The 'K30' suffix indicates that the bearing has a tapered bore with a taper of 1:30. This design allows for mounting on a tapered shaft journal or using an adapter or withdrawal sleeve on a cylindrical shaft, enabling a secure and precise fit.

Question?
How does the 'CC' designation impact the performance of this bearing?
Answer:
The 'CC' designation refers to an improved internal design featuring two window-type steel cages and symmetrical rollers. This enhances roller guidance, reduces friction, and allows for higher speed ratings compared to older designs, contributing to the bearing's overall performance and longevity.

Question?
Is special lubrication required for a bearing with the 'W33' feature?
Answer:
The 'W33' feature, which is an annular groove and three lubrication holes in the outer ring, does not require a special type of lubricant but facilitates more effective and efficient relubrication. It allows grease or oil to be introduced directly into the load-bearing zone, ensuring optimal lubrication, heat dissipation, and contaminant flushing.
