Product Overview

The SHFZ Series of shoulder (flanged) oilless bushings are high-performance, self-lubricating bearings designed for high-load, low-speed applications where regular maintenance is difficult or impossible. Manufactured from a high-quality, centrifugally cast bronze alloy base, these bushings are embedded with a specially formulated solid lubricant. The integrated flange (shoulder) design not only provides excellent radial support but also handles axial thrust, serving as a locator and wear surface. This makes the SHFZ bushing an ideal, maintenance-free solution for long-life performance.

Key Features

Completely Self-Lubricating: The embedded solid lubricant forms a durable lubricating film during operation, eliminating the need for oil or grease. This significantly reduces maintenance costs and prevents environmental contamination.
Superior Wear Resistance: The high-strength bronze alloy base offers exceptional load-carrying capacity and impact resistance, ensuring a long service life even under heavy loads.
Integrated Shoulder Design: The flange handles both radial and axial loads simultaneously, simplifying mechanical designs and providing reliable axial positioning.
High-Precision Tolerances: Manufactured to strict industry standards with an inner diameter tolerance of dE7, and outer/seating diameter tolerances of Dr/H7, ensuring a precise fit and stable operation.
Wide Temperature Range: Performs reliably across a broad range of operating temperatures, making it suitable for various demanding industrial environments.
Wide Range of Sizes: Available in standard sizes with inner diameters from 6mm to 30mm. Custom dimensions are available upon request to meet specific application needs.
