Structural Features of KH3050pp/KH3050 Linear Bearings:

Core Structure: Adopts the classic linear bearing configuration of “outer sleeve + cage + balls.” Balls are evenly distributed within the cage grooves, enabling low-friction linear motion through ball rolling. This design offers simplicity and ease of assembly.

Cage Design: Features a resin cage that stably separates balls, preventing mutual friction and collision during rolling. It also guides smooth ball circulation, enhancing motion stability and precision.

Sealing Structure Differences: KH3050pp incorporates sealing lips at both ends to effectively block dust and contaminants while preventing grease leakage. KH3050 features an open design suitable for applications with lower cleanliness requirements or frequent grease replenishment.

Outer Sleeve and Fit Method: The outer sleeve is made of high-carbon chromium steel with a precision-machined inner surface. It forms a clearance fit with the shaft, ensuring movement flexibility while distributing loads through point contact between the balls and shaft. This design accommodates medium to low load conditions.
