The SKF 22317 bearing is a robust spherical roller bearing designed for heavy-duty applications, offering high radial and axial load capacity. Its self-aligning capability compensates for shaft misalignment and housing deformation, ensuring reliable performance in harsh operating conditions.

The detailed suffix model parameters of SKF 22317 bearings are as follows:
1、 Basic model parameters
Inner diameter/outer diameter/thickness: 85mm/180mm/60mm;
Dynamic/static load: 550kN (dynamic)/620kN (static);
Speed limit: 2800rpm for grease lubrication and 3800rpm for oil lubrication.
2、 Difference in suffix models
‌22317CC/W33‌
Structural features: The cylindrical hole has no sealed design, making it highly versatile;
Adaptation scenario: Conventional industrial equipment such as gearboxes and transmission shafts.
22317K (old model 22317EK)
Structural features: The conical hole is not sealed and needs to be installed with a tightening sleeve;
Adaptation scenario: Shaft systems that require frequent adjustment or disassembly.
‌22317 EK‌
Structural features: SAF series split bearing seat special model, including cylindrical hole;
Sealing options: Supports seals such as PosiTrac and iron flint;
Adaptation scenario: Vertical bearing seat for mining and heavy-duty machinery.
‌SAF22317‌
Structural features: Split vertical bearing seat kit, including cylindrical hole spherical roller bearings;
Installation features: Supports labyrinth sealing, Taconite sealing, etc.
3、 Selection suggestions
Sealing requirements: Non sealed models (such as CC/W33, K) are suitable for regular maintenance scenarios; Sealed models (such as those with TLC/TSK suffix) are suitable for dusty environments;
Installation method: Conical hole models (such as K) require a tightening sleeve, while cylindrical hole models (such as CC/W33) are suitable for fixing shafts.
Different suffixes correspond to specific working conditions, and it is recommended to choose comprehensively based on sealing, installation method, and load conditions
