Sinopec Great Wall L-FD Bearing Oil Anti Wear Rust Prevention Spindle Oil

Sinopec Great Wall L-FD Bearing Oil Anti Wear Rust Prevention Spindle Oil

Sinopec Great Wall L-FD Bearing Oil — Anti Wear Spindle Oil for High-Speed Machinery

Great Wall L-FD Bearing Oil is an anti-friction lubricant developed by Sinopec for high-speed rotating equipment. Blended from deeply refined base oil and multifunctional additives, this spindle oil delivers reliable protection for textile spindles, precision machine tool shafts and sliding bearings in light-load circulating systems.

Every batch of L-FD is produced under strict quality control at Sinopec lubricant facilities and verified against SH/T 0017-90 (1998) before release. Laboratory testing covers viscosity, oxidation stability, rust prevention and foam resistance, so maintenance teams can rely on consistent performance in demanding production environments.

Selecting the right viscosity grade is straightforward: lower ISO VG grades suit higher spindle speeds and tighter clearances, while higher grades provide extra film strength for heavier loads. This L-FD range gives equipment engineers flexibility across textile, machine tool and light industrial applications.

Product Q&A

Q1: What is L-FD bearing oil used for?
L-FD is designed for high-speed spindles, precision machine tool shafts, sliding bearings and other light-load circulating lubrication systems where reliable anti wear protection is required.

Q2: Why choose an anti wear spindle oil?
The anti wear additives form a durable oil film between moving surfaces, reducing friction and wear during high-speed operation and extending the service life of spindles and bearings.

Q3: How do the ISO VG grades differ?
The ISO VG number indicates kinematic viscosity at 40°C. Engineers select a lower viscosity grade for high-speed spindles with tight clearances, and a higher grade for heavier loads and slower speeds.

Q4: How does rust prevention protect equipment?
Rust prevention additives form a protective barrier on metal surfaces, shielding spindles and bearings from moisture and acidic contaminants that could otherwise cause corrosion and premature failure.

Q5: Does the oil foam during circulating use?
No. L-FD has good foam resistance, keeping the oil stable in circulating systems and preventing foam-related lubrication failures.

Q6: Which standard does L-FD comply with?
L-FD complies with SH/T 0017-90 (1998), covering viscosity, oxidation stability, rust prevention and foam requirements for anti-friction bearing oils.
