Anti Wear Sinopec Great Wall L-FD 2 Bearing Oil Ultra High Speed Spindle Oil ISO VG 2

Sinopec Great Wall L-FD 2 Bearing Oil Ultra High Speed Spindle Oil ISO VG 2 Anti Wear

Sinopec Great Wall L-FD 2 Bearing Oil - Ultra High Speed Spindle Oil ISO VG 2

Product Overview

Sinopec Great Wall L-FD 2 bearing oil is a ultra high speed grade of the L-FD spindle and bearing oil series, blended from deeply refined base oil and multifunctional additives. With a kinematic viscosity of 2.016 mm²/s at 40°C, this ISO VG 2 spindle oil is formulated for very high speed spindles of textile machinery and ultra-fine precision spindles with minimal clearances. The balanced additive package provides good oxidation stability, effective wear protection, reliable rust and corrosion prevention, and low foaming behaviour in circulation service.

Produced under the Great Wall brand by Sinopec, one of the largest lubricant and specialty fluid manufacturers in Asia, this L-FD 2 bearing oil is manufactured under a strict quality management system and conforms to SH/T 0017-90 (1998). Every batch is tested for viscosity, oxidation stability, rust prevention, foaming characteristics and wear protection before delivery, which ensures stable and predictable performance in the field. The typical values shown below come from factory test records for the L-FD 2 grade, and a certificate of analysis for the actual supplied batch is available on request.

Typical Technical Data (L-FD 2)

The table below lists typical values of the L-FD 2 grade. Actual values may vary slightly from batch to batch.

Key Performance Advantages

• Good oxidation stability that gives the oil a long service life even under continuous high-speed operation
• Good lubricity that effectively reduces friction and wear on spindles, shafts and bearing surfaces
• Good rust and corrosion prevention that protects equipment from rusting during operation and standstill
• Good anti-foaming performance, so the oil does not readily form foam in circulation systems
• Precise ISO VG 2 viscosity matched to ultra high speed textile spindles
• Full compliance with the SH/T 0017-90 (1998) specification

Applications

• Very high speed spindles of textile machinery and ultra-fine precision spindles with minimal clearances
• Oil bath, splash and circulation lubrication systems with light load conditions
• Equipment requiring a clean, low-viscosity bearing oil with good rust protection
• Select the viscosity grade according to spindle speed, bearing clearance and operating temperature; consult the technical data sheet or our team for grade selection support

Frequently Asked Questions

Q1: What is L-FD 2 bearing oil used for?
A: L-FD 2 is a spindle and bearing lubricating oil designed for very high speed spindles of textile machinery and ultra-fine precision spindles with minimal clearances. Its ISO VG 2 viscosity provides a thin but durable oil film that protects precision surfaces without creating excessive drag at high rotational speeds.

Q2: Why is the ISO VG 2 viscosity important?
A: Viscosity determines the thickness of the oil film between moving surfaces. At 2.016 mm²/s at 40°C, this L-FD 2 oil is matched to components that run at high speed with small clearances, where a heavier oil would increase friction and temperature while a lighter oil might not provide enough film strength.

Q3: Why is anti-foaming performance important?
A: Foam in a circulating oil system reduces lubrication efficiency, can cause unstable oil pressure and accelerates oxidation. The anti-foaming additives in this bearing oil keep foam formation low when the oil is circulated and returned to the sump, protecting both the oil and the machine.

Q4: How does the oxidation stability extend service life?
A: The deeply refined base oil and selected antioxidants resist oxidation under the heat and churning of high-speed operation. Slower oxidation means less sludge and acid formation, longer oil life, fewer oil changes and lower maintenance costs.

Q5: Does this oil protect machines against rust?
A: Yes. The formulation includes rust and corrosion inhibitors that protect ferrous surfaces from rusting, which is particularly valuable for machines that operate intermittently or stand idle for periods, and for circulation systems where moisture can accumulate.

Q6: Which specification does the oil comply with?
A: The L-FD series complies with SH/T 0017-90 (1998), the Chinese industry standard for spindle and bearing lubricating oils. The oil is produced under the Great Wall brand by Sinopec under a strict quality management system.

Q7: What documentation and packaging are available?
A: A certificate of analysis for the supplied batch is provided with each delivery of this bearing oil, together with the packing list and shipping documents. The oil is available in 200L new iron drums, 1000L IBC totes and bulk supply, and the safety data sheet and product datasheet can be supplied before shipment on request.

Summary

In short, Sinopec Great Wall L-FD 2 combines the trusted Great Wall brand, a precise ISO VG 2 viscosity, and a balanced formulation of oxidation stability, anti wear protection, rust prevention and anti-foaming performance. For maintenance teams and machine builders that need a dependable spindle oil for ultra high speed textile spindles, this L-FD 2 bearing oil offers reliable protection and long service life, supported by specification compliance and factory test documentation.
