Product detailed description
INA KSO20-PP is an open self-aligning linear ball bearing designed for linear motion on a precision guide shaft with a diameter of 20 mm. Its open design allows it to be used with supported guide shafts, providing greater rigidity and reduced shaft deflection, especially in applications with longer travel distances or higher loads.
This bearing belongs to INA’s heavy-duty range of linear bearings intended for demanding industrial applications. The self-aligning design helps compensate for minor misalignment between the shaft and housing, supporting smooth operation and reducing unwanted internal stress.
Meaning of the KSO20-PP designation
- KSO – open self-aligning linear ball bearing for supported guide shafts,
- 20 – nominal guide shaft diameter of 20 mm,
- PP – lip seals fitted on both sides of the bearing.
Main features
- smooth and precise linear motion,
- open design for supported guide shafts,
- self-aligning construction compensating for minor misalignment,
- lip seals on both sides protecting against contamination and lubricant loss,
- suitable for applications requiring high rigidity and load capacity,
- manufactured by INA, part of the Schaeffler Group.

Applications
The INA KSO20-PP linear bearing is suitable for industrial machinery, production lines, automation systems, handling equipment, machine tools, packaging machinery and other equipment using linear guide systems.
For correct operation and the expected service life, the bearing should be used with a dimensionally suitable, precision-hardened and ground guide shaft. The open KSO20-PP design is primarily intended for shafts supported along their entire length.
Important: Before ordering, we recommend checking the complete designation of the original bearing, its dimensions, design, mounting arrangement and operating conditions. Linear bearings with similar designations may not be fully interchangeable without technical verification.
