DJA MOND Fibre Bushings
Self-lubricating bushings
- Very high load capacity
- Long-term dry-running operation
Fibre bushings are plain bearings manufactured with a glass fibre and epoxy resin structure, designed to withstand loads up to 140 MPa in dry-running conditions. The DJA MOND FWB.. series features an outer layer made of high-strength glass fibres reinforced with epoxy resin, combined with a lubricating layer consisting of PTFE-wrapped fibres or special self-lubricating fibres. This construction provides outstanding wear resistance and a low coefficient of friction in high-load, low-speed applications. Compared with other self-lubricating materials (sintered bronze, multilayer PTFE and engineering polymers), fibre bushings offer the highest load-carrying capacity at low speeds, making them the preferred solution when load capacity is the primary design requirement rather than rotational speed.
Specifications
Technical specifications of fibre bushings
Base material
High-strength glass fibre reinforced with epoxy resin; lubricating layer made of PTFE-wrapped fibres or special self-lubricating fibres.
Maximum load capacity
140 MPaCoefficient of friction
0.03 – 0.12 (depending on load, displacement method, sliding speed and roughness of the mating surfaces)
Lubrication
Not required (extended dry operation without oil lubrication)
Performances
Design and performance features
Load
Up to 140 MPa, with excellent wear resistance even under high-load, low-speed conditions.
Reduced coefficient of friction
Between 0.03 and 0.12: it decreases with increasing load under rotational movement conditions. The value depends on load, displacement method, sliding speed and roughness of the mating surfaces.
Wear concentrated during the initial phase
During the running-in phase, the lubricant is transferred from the inner lining, forming a smooth lubricating surface. After running-in, the bearing remains stable with no significant wear.
Excellent chemical resistance
Together with their high load-carrying capacity, this makes fibre bushings a reliable and robust solution even in chemically aggressive environments.
Applications
Applications
Components and application support for every industrial environment.
Construction Equipment
Components operating under very high loads and low speeds, where a load capacity of up to 140 MPa is the key performance factor.
Hydraulic and pneumatic cylinders
High-load, low-speed applications where excellent wear resistance is required, even under severe conditions.
Metal Fabrication / Machining Industry
Structural applications where load-carrying capacity is the critical parameter and prolonged dry-running reduces maintenance costs.
Agriculture
