Low-Temperature Gear Grease Under Extremely Low-Temperature Conditions

1.Description

XYC low-temperature gear grease can maintain a lubricating film under extremely low-temperature conditions, reduce start-up torque, inhibit wear and corrosion, extend equipment life, and reduce downtime for maintenance.

2.Main Parameters and Indicators (Reference Range) 

NLGI grade: 000 to 2 (000, 00, 0 or 1 are commonly used for low-temperature applications; for gears and bearings, softer or slightly thicker grades can be selected depending on speed and load)

Base oil viscosity (at 40°C): 50 - 500 cSt (Selection should be based on load and operating temperature)

Pour point / Pour point determination: Can operate at -60°C to -40°C (depending on the formula)

Low-temperature starting torque / Low-temperature fluidity: It can maintain an acceptable starting torque at -40°C to -50°C initially (laboratory low-temperature torque test index)

Dropping point: Usually >180°C (It characterizes high-temperature stability, but for low-temperature fats, its importance is secondary to low-temperature fluidity.)

Operating temperature range: approximately -60°C to +120°C (varies greatly depending on specific formula)

Rust protection (salt spray/steel sheet test): Excellent grade (with anti-rust additive)

Water wash resistance / moisture resistance: Good (suitable for cold storage cleaning or high humidity scenarios)

Extreme pressure/anti-wear properties (EP & AW): Solid lubricants (such as MoS₂, graphite) or extreme pressure additives can be added according to the gear load.

3.Product Feature Highlights

Excellent low-temperature fluidity - The combination of synthetic base oil and low-temperature optimized thickener ensures the formation of a lubricating film at extremely low temperatures.

Low starting torque - can significantly reduce the instantaneous load on the motor/reduction mechanism during low-temperature startup, and relieve the pressure on the starting device.

Anti-wear and anti-pressure - Provides a stable oil film even at low temperatures, reducing wear on gear surfaces and bearings.

Water resistance and anti-corrosion - Containing anti-corrosion additives, it is suitable for damp and cold environments as well as cleaning conditions in cold storage.

Long service life and maintenance-free - Good oxidation resistance and shear stability, extend the grease change cycle and reduce maintenance costs.

Food-grade option available - For food cold chain applications, we offer low-temperature greases that meet food contact or H1 requirements (please refer to specific qualification certificates).

4.Applicable scenarios

(1).Gears, rolling and sliding bearings for cold storage conveyor lines: sprockets, roller bearings, input shafts of reducers, etc.

(2).Bearings for refrigeration machines and refrigeration compressors: low-temperature startup and long-term operation under low-temperature conditions.

(3).Gears and bearings of port/outdoor equipment in winter: loading and unloading machines, gantry cranes, sliding rails, etc.

(4).Refrigerated transport vehicles and refrigerated containers: wheel bearings, door hinges, drive gears.

(5).Low-speed gears and rotating devices for scientific research stations or polar measurement stations.
