Marginal Lubrication Bearing Steel Backing DIN 1494 Standard refers to a type of bearing component that incorporates a steel backing with marginal lubrication features, adhering to the DIN 1494 standard. This standard specifies the requirements for the design, material, and performance of such bearings, ensuring their reliability and durability in various industrial applications.
The steel backing provides a rigid and stable foundation for the bearing, supporting the load and maintaining the shape and position of the bearing surface. The marginal lubrication feature allows for effective lubrication even in conditions where traditional lubrication methods may be inadequate. This helps to reduce friction and wear, extending the bearing's lifespan and improving its performance.
By adhering to the DIN 1494 standard, Marginal Lubrication Bearing Steel Backing ensures compliance with industry-recognized quality and safety requirements. This ensures that the bearings are suitable for use in a wide range of industrial settings, including high-load and high-speed applications.
In summary, Marginal Lubrication Bearing Steel Backing DIN 1494 Standard offers a robust and reliable bearing solution that combines the strength and stability of steel with effective marginal lubrication. This combination ensures smooth and efficient operation, reduced wear, and longer bearing lifespan, making it a valuable addition to any industrial equipment or machinery.

Marginal Lubrication Bearing Steel Backing DIN 1494 Standard
Features:
Lubrication Bearing Steel Backing Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The ptfe bushing improved the friction and much good wear resistance over the common PTFE range under lubricated operation.

Structure:
1. PTFE/Fibre mixture thickness 0.01~0.03mm. It is the contact surface for the rotating shaft. Minute parties of the PTFE layer and the sintered bronze material combine to create a solid lubricant film, which coats the shaft.
2. Sintered bronze powder thickness 0.20*0.35mm, A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build-up away from the bearing surfaces.
3. Low-carbon steel backing. Setting the foundation of the
bushings, the steel back provides exceptional stability, load
carrying, and heat dissipation characteristics.
Typical Applications:
1. This material meets the demanding criteria for long life and
maintenance-free performance with or without lubrication.
Automotive: tractors, combines, crop sprayers, earth-movers,
graders and other construction, auto machines, specific uses in
power steering cylinders, steering gear thrust washers, disc
brakes, calipers and pistons, shock absorbers, governor linkage,
windshield wiper motor, tilt gear assemblies...
2. Business machines: photocopy machines, typewriters, mail
sorters, postage meter systems, computer terminal printers and
peripheral equipment,automatic printing devices, mail processing
machinery...
Hydraulics and valves: pumps including gear, rotary, water, axial
piston, and other types, ball, butterfly, poppet steam, and other
valves and valve trunnions...
3. Home appliances: tape recorders, refrigerators, air
conditioners, cleaners, polishers, sewing machines, ovens,
dishwashers, clothes washing machines...And materials handling,
marine engine, packaging, textile equipment, tools...etc.
