The Pillow Block Flange Bearing from SHENGFA combines a compact housing design with adjustable mounting features to support machinery where installation space is limited and shaft positioning accuracy is important.
The bearing uses an 8mm inner diameter design with 5mm mounting holes and 37mm hole spacing, providing a practical configuration for small mechanical assemblies requiring stable shaft support.
Its overall dimensions are:
| Specification | Details |
|---|---|
| Inner Bore Diameter | 8mm / 0.31 inches |
| Mounting Hole Diameter | 5mm / 0.2 inches |
| Mounting Hole Spacing | 37mm / 1.46 inches |
| Overall Size | 48mm × 27mm × 11mm |
| Housing Material | Zinc alloy |
| Machining Process | CNC precision machining |
Unlike standard pillow blocks that mount parallel to the shaft axis on flat base pedestals, a flange housing mounts perpendicular to the machine frame. This vertical mounting orientation supports axial penetration through bulkheads, frame walls, and machine side plates while maintaining precise perpendicularity.
Shaft deflection and structural distortion under load cause premature raceway spalling in rigid bearing mounts. The SHENGFA Pillow Block Flange Bearing integrates an adjustable vertical surface design. This self-positioning feature compensates for minor angular misalignments during frame assembly, ensuring even load distribution across all rolling elements.
While traditional cast iron housings are heavy and prone to cracking under localized impact, high-grade die-cast zinc alloy delivers exceptional structural yield strength and corrosion resistance. The precision CNC-polished outer surface aids thermal dissipation, preventing heat accumulation during extended high-speed operation.
Due to its compact structure and adjustable mounting characteristics, the Pillow Block Flange Bearing is applied across multiple industries requiring reliable shaft rotation support.
Typical applications include:
The bearing supports conveyor shaft rotation and helps maintain smooth material movement during continuous operation.
Agricultural equipment benefits from compact bearing structures that can operate under changing loads and outdoor conditions.
High-speed machinery requires stable shaft positioning to maintain consistent production accuracy.
Precision shaft rotation support helps maintain stable mechanical movement during printing operations.
Bearing selection plays an important role in maintaining reliable operation in environments where equipment cleanliness and stability are important.
Match the nominal shaft diameter directly to the bearing bore size (8mm / 0.31 in). Verify that the mounting pitch (37mm / 1.46 in) aligns with existing frame hole patterns. For custom shaft tolerances or non-standard metric/imperial shafting, SHENGFA provides custom CNC machining options.
