XYC GDB2-68 1KG Sintered Bearing Lubricant Bearing Oil for Oil Impregnated Bearings
XYC GDB2-68 Sintered Bearing Lubricant
XYC GDB2-68 is a high viscosity sintered bearing lubricant developed for powder metallurgy sintered metal sliding bearings. It is designed as a supplementary lubricant during bearing assembly, providing additional lubrication for bearings that have already been impregnated with a suitable base oil.
As a bearing oil, XYC GDB2-68 uses an ester oil and synthetic hydrocarbon formulation. The ISO VG 68 viscosity grade provides a relatively thick oil film, making this sintered bearing lubricant suitable for applications where higher load capacity and lower to medium operating speeds require additional oil film support.
Bearing Oil for Oil Impregnated Bearings
XYC GDB2-68 is intended for oil impregnated bearings used in powder metallurgy applications. During assembly, the bearing oil can be applied directly to the bearing surface or pores to provide an additional lubricant supply.
For suitable oil impregnated bearings, the additional lubricant can help increase the amount of available oil within the bearing system. This makes XYC GDB2-68 a practical sintered bearing lubricant for components designed for long service intervals or applications where regular relubrication is difficult.
Ester Oil and Synthetic Hydrocarbon Formulation
The formulation of XYC GDB2-68 combines ester oil and synthetic hydrocarbon and does not contain silicone oil. This silicone-free composition makes the bearing oil suitable for applications where silicone contamination may interfere with subsequent coating, bonding or related manufacturing processes.
The ester and synthetic hydrocarbon formulation also provides good oil adhesion to suitable sintered metal surfaces. The sintered bearing lubricant can therefore be considered for automated production processes requiring controlled application during assembly.
High Viscosity Oil Film
With an ISO VG 68 viscosity grade, XYC GDB2-68 provides a thicker oil film compared with lower viscosity bearing lubricants such as GDB2-32. This bearing oil is particularly suitable for oil impregnated bearings operating under relatively higher loads and low to medium speeds.
The thicker lubricant film helps provide additional lubrication support at the bearing contact area. The sintered bearing lubricant can be used when the application requires additional oil film thickness while maintaining the characteristics of a synthetic liquid lubricant.
Wide Temperature Operating Range
XYC GDB2-68 has a specified operating temperature range from approximately -40°C to +200°C. The bearing oil is designed to provide stable lubrication across a wide range of operating conditions.
Its good thermal stability and aging resistance make this sintered bearing lubricant suitable for demanding bearing applications where temperature cycling and long operating periods are important considerations.
Rust and Corrosion Protection
XYC GDB2-68 provides rust and corrosion protection for suitable sintered metal bearing materials, including iron-based, bronze and copper-iron powder metallurgy components.
Foroil impregnated bearings, the combination of lubrication and corrosion protection helps support reliable long-term operation. This bearing oil can be considered for applications where both lubrication performance and protection of the sintered metal structure are required.
Assembly Lubrication Applications
XYC GDB2-68 is primarily intended as an assembly-stage supplementary lubricant rather than the original impregnation oil. It can be used together with a compatible sintered bearing impregnation oil such as Klübersynth DB 2-68.
Thesintered bearing lubricant can be applied to suitable oil impregnated bearings during automated or batch assembly processes. Its good adhesion and ISO VG 68 viscosity make the bearing oil suitable for applications requiring additional lubricant before final assembly.
Typical Applications
XYC GDB2-68 can be considered for powder metallurgy sintered metal sliding bearings used in precision motors, household appliances, office equipment, small drive mechanisms and automotive micro motors.
For these oil impregnated bearings, the additional bearing oil supply can help support long-life lubrication and reduce the need for later maintenance. The sintered bearing lubricant is especially suitable for applications requiring a relatively thick oil film and reliable lubrication under higher load and lower speed conditions.
