This is a heavy-duty KP004 20mm zinc alloy pillow block bearing designed for mechanical shaft support in 3D printers, CNC machines, and robotics. It features a self-aligning ball bearing insert that corrects angular misalignment between the shaft and housing. The durable zinc-alloy housing includes two pre-drilled mounting holes for secure anchoring and integrated grub locking screws to firmly grip the rotating shaft.
Product Overview
The KP004 Zinc Alloy Pillow Block Bearing is a high-performance, mounted mechanical assembly engineered to provide stable, low-friction rotational support for drive shafts. This unit pairs a heavy-duty, corrosion-resistant housing with an integrated, dual-sealed ball bearing insert. Specifically designed for precise linear and rotary machinery—such as custom CNC routers, industrial 3D printers, and automated conveyor systems—it eliminates shaft wobble and accommodates structural misalignments under high-stress operating conditions.
Design & Premium Features
Engineered for longevity and seamless integration into mechanical frameworks:
- Self-Aligning Internal Structure: The ball bearing unit features a spherical outer ring that mirrors the curved profile inside the housing cavity. This unique geometry allows the bearing insert to pivot independently, automatically correcting angular misalignments between the support frame and the rotating shaft.
- Double-Shielded Protection: The bearing insert is outfitted with rubber-reinforced metal seals on both sides. These dual shields trap grease deep within the rolling channels while forming a tight defensive barrier against harmful airborne dust, fine metal shavings, and moisture.
- Secure Shaft Locking: Features a wide, extended inner ring equipped with dual integrated hexagonal grub screws. When tightened against the inserted shaft, these locking pins create a secure friction hold that prevents axial slipping or rotational spinning along the shaft surface.
- Rigid Zinc-Alloy Housing: Cast from premium zinc-aluminum alloy, the lightweight bracket delivers structural rigidity and excellent shock absorption while remaining completely resistant to surface rust and atmospheric corrosion.
