Precision-Designed for Performance and Durability
Engineered Bushings & Sleeve Bearings That Stand Out In High-Load, Low-Speed Applications
For over 50 years, HEF NA has been designing and developing high-performance bushings, bearings, and joints built to handle tough conditions in industries like construction, mining, steel processing, transportation, forestry, material handling, and agriculture. Known worldwide for their outstanding frictional and anti-seizure properties, as well as their ability to handle heavy loads, HEF NA bushings are the go-to choice for applications that require longer intervals between lubrication.
HEF NA offers a range of patented bushing designs in various sizes, along with carburized and ground sleeve bearings. To find the best fit for your application, it’s important to consider factors like abrasion, loading, corrosion, and maintenance needs.
Three factors combine to give our engineered bushings exceptional serviceability for high-load/low rotational speed applications:
- Optimized steel selection and heat treatment for strength and durability
- Patented surface treatments that enhance performance
- Patented surface topographies, including ID cross-hatching and surface cavities

When choosing bushings & sleeve bearings, consider the following selection criteria...
The pressure-velocity (PV) factor is key. In dry or greased joints, friction generates heat based on pressure (P), sliding velocity (V), and the friction coefficient (F). Every material pair has a PV limit—exceeding it can cause surface seizure or melting. Each HEF bushing design has its own PV curves, which are essential for ensuring the right fit for specific applications and operating conditions.
