This linear ball bearing enables low-friction linear motion along a shaft, using recirculating ball tracks in an open, lightweight design. Bore diameter is 25.0 mm, outside diameter 40.0 mm, and net mass is 0.113 kg. The housing is sealed on all sides, protecting the ball tracks from contamination while allowing relubrication during operation. The adjustable angle feature allows compensation for slight misalignment between the shaft and the mounting, easing installation where perfect parallelism cannot be guaranteed. Seals on both sides retain lubricant and keep out dust and debris, supporting stable operation over extended service intervals. The open design and lightweight construction of the KNO25-B-PP make it suitable for applications where axial mass and load capacity align with these dimensions and where periodic relubrication access is required.
