NN30-Box Type Linear Bearing Slide Block for CNC Corner Nailer

Box Linear Bearing Slide Block CNC Corner Nailer – NN30 SCS25UU

The box linear bearing slide block CNC corner nailer NN30 is a precision linear motion component that enables smooth, accurate movement of the nailer carriage and positioning system on CNC corner nailers. Worn or damaged linear bearings cause jerky carriage movement, positioning inaccuracies, and increased wear on other components. Replacing with a new NN30 restores precise, friction-free linear motion.

How Linear Bearing Slide Blocks Work

The box linear bearing slide block CNC corner nailer NN30 contains a sealed linear ball bearing mounted inside an aluminum housing. As the bearing housing slides along the guide shaft, the ball elements recirculate in their raceways, providing smooth rolling contact with minimal friction. The box-type housing (SCS type) adds four mounting bolt holes on the flat aluminum body, allowing direct bolting of the block to the moving carriage or table plate without additional fixtures.

Specifications

The NN30 is an SCS25UU type linear bearing block with a 25mm bore (for 25mm guide shafts). The aluminum housing measures 50mm in height, 67mm in depth, and 73mm in width. Four mounting holes are positioned symmetrically on the housing face. The internal bearing is a sealed LM25UU-type linear ball bearing with end seals to retain lubrication and exclude contaminants.

Application in CNC Corner Nailers

CNC corner nailers use linear guide systems to move the work platform or nailer head along programmable axes. The box linear bearing slide block CNC corner nailer NN30 is a wear part in these guide systems. After extended high-cycle use, the ball elements wear and the bearing develops play, reducing positioning accuracy. Periodic replacement of linear bearing blocks is part of preventive maintenance for CNC corner nailers.

Installation Notes

When replacing the NN30 on your CNC corner nailer, ensure the guide shaft surface is clean and free of rust or scoring before installing the new block. Apply a thin film of linear bearing grease to the shaft. Slide the new block carefully onto the shaft—never force it as this can damage the ball elements. Torque the mounting bolts evenly to prevent housing distortion.

Compatibility

The NN30 is compatible with CNC corner nailers that use 25mm diameter linear guide shafts. Verify the shaft diameter on your specific machine. XKY Framing stocks the NN30 as a standard replacement item alongside other CNC corner nailer maintenance parts including the proximity switch (NN21) and air pressure gauge (NN16).
