Self-lubricating bushings

High sliding velocity

Five types designed for every operating condition, from extreme dry running to food processing environments.

DJA MOND self-lubricating bushings operate without external lubrication, as the lubricant is integrated into the material itself, either in the form of a solid polymer layer or oil impregnated within a porous structure. During operation, the lubricant is gradually transferred to the sliding surfaces, providing exceptional benefits: maintenance-free operation, extended service life and reliable performance even in hard-to-reach applications.

Five types for every operating condition

The five types in this range differ in material, design technology, load capacity and temperature range, with each version optimized for specific operating conditions. Dry-running self-lubricating bushings with solid lubricant inserts (BG/AG/CG) are the choice for heavy loads and extreme temperatures, featuring a solid metal body. PTFE multilayer self-lubricating bushings (PT..SL) excel at high sliding speeds with reduced operating clearance. Sintered bronze and iron bushings (BZ/FE) are ideal for high rotational speeds and cost-effective production batches. Technopolymer bushings (EPB) offer lightweight design and chemical resistance for medium to light loads. Fiber bushings (FWB) ensure load capacities up to 140 MPa with extended dry-running operation.

SELECTION GUIDE

Start by identifying the operating conditions

JFK’s DJA MOND self-lubricating bushings cover a broad range of applications: from high-temperature environments and high-frequency operating cycles to situations where lubrication is not possible or where contact with food or water is a critical requirement. Start by identifying the operating condition that best matches your application.

High-temperature environments

Solid lubricant inserts that retain their performance up to +300°C, even without pre-lubrication.

High-speed continuous movements

PTFE layer that stabilizes during running-in, providing low friction at high speeds, reduced clearance and virtually no stick-slip effect.

Motors, actuators, high-frequency cycles

Continuous oil film released by the porous structure. Good performance-to-cost ratio, suitable for large production batches and custom-designed geometries.
