INA KGBS 50 PP AS - Linear Bearing Unit with Housing

Designed for Precision Linear Motion

The INA KGBS 50 PP AS is a linear bearing unit with housing, engineered for smooth and accurate guidance of shafts with a 50 mm diameter. It is widely used in industrial automation, CNC systems, packaging machinery, transport units, and applications requiring stable, repeatable linear motion under continuous load.

Construction and Operational Benefits

This unit integrates a recirculating ball linear bearing (PP - sealed design) into a robust AS mounting housing, providing both structural stability and protection against dust and external contaminants. The compact housing ensures easy installation, while the sealed bearing offers extended service life and reduced maintenance intervals.

Main Description

The INA KGBS 50 PP AS is a complete linear bearing assembly designed for high-precision shaft-guided motion. The internal linear bearing uses a recirculating ball track to minimize friction while maintaining tight guidance tolerances. This ensures accurate linear travel and stable support, even when operating under continuous load cycles or vibration conditions.

The PP sealing system protects internal rolling elements from debris, dust, and moisture, which is essential in industrial environments. This not only maintains smooth movement but also significantly extends the service life of both the bearing and the shaft. The AS housing is designed to be rigid and dimensionally stable, enabling secure mounting on machine frames, modular profiles, or custom equipment bases.

Typical industrial applications include:

• CNC machine axes and gantry positioning systems

• Pick-and-place and robotic automation stages

• Industrial transport rollers and conveyor guides

• Packaging and cutting equipment

• Mechanical assembly and inspection systems
