Get quoteThe swivel caster wheel corner cutting machine NN31 is a durable replacement caster that keeps your corner cutting machine mobile and maneuverable on the workshop floor. Corner cutters are frequently repositioned during setup, maintenance, and production changes—quality caster wheels are essential for safe, easy machine movement.
Corner cutting machines can weigh significantly and are often moved to different positions in the workshop for material handling access or maintenance. Worn caster wheels can seize, crack, or lose their swivel function, making machine repositioning difficult and potentially causing tip-over hazards. Replacing worn casters with new NN31 swivel caster wheels corner cutting machine parts maintains safe, effortless machine mobility.
The NN31 features a black rubber wheel for floor protection, mounted on a steel swivel bracket with 360° rotation on a ball-bearing swivel plate. Overall height from floor to mounting plate is 77mm. The flat bolt plate measures 70mm in length and 50mm in depth, with 4 bolt holes for secure fastening to the machine base frame. The swivel lock bolt on the bracket can be tightened to fix the wheel direction when needed.
The black rubber tire on the NN31 swivel caster wheel corner cutting machine provides: floor protection (no scratching), noise reduction during movement, vibration absorption, and adequate grip to prevent unwanted machine drift during operation. The rubber compound is suitable for smooth concrete workshop floors typically found in frame production facilities.
Bolt the NN31 onto the corner cutting machine’s base frame using the 4-hole plate and appropriate bolts. Ensure all four casters are aligned horizontally for stable, level machine positioning. Tighten mounting bolts securely as loose casters create instability during cutting operations.
