72637 XCMG GR2605 motor grader lubricating oil cup

The 72637 lubricating oil cup is a small, manual, refillable lubrication point storage and supply device used in construction machinery. It is mainly used for timed and metered application of grease to friction points such as bearings and pins under low speed and light load, playing a basic maintenance role in reducing friction and preventing wear and corrosion.

Core Technical Parameters

Model: 72637, a common standard manual lubricating oil cup, mostly a universal model, selectable according to the installation thread specification.

Suitable Media: Suitable for most general-purpose lithium-based greases, calcium-based greases, and other commonly used lubricants in construction machinery.

Material: The cup body is usually made of transparent or semi-transparent engineering plastic (such as PC, nylon) for easy observation of the oil level; the cup cap and oil-pressing parts are made of plastic or metal; the bottom threaded connector is mostly metal.

Operating Temperature: -20℃ ~ 80℃, adaptable to the normal operating environment temperature of the equipment, ensuring the plastic cup body does not deform or crack.

Sealing Performance: A seal is achieved through the mating of the sealing ring or precision threads at the cup lid, cup body, and threaded joint, preventing dust and moisture ingress and grease leakage.

Capacity: Common specifications include 20g, 30g, and 50g, selectable according to lubrication point consumption.

Installation Interface: Standard metric or imperial threads (e.g., M10×1, 1/8″ NPT), matching the pre-drilled threaded holes at the equipment’s lubrication points.

Core Functions and Roles

As a basic and economical centralized lubrication point replenishment device, its core function is to store a small amount of grease and manually press the cup lid to force the grease through the bottom joint into the bearings, bushings, open gears, or movable pins requiring lubrication. It provides a clean grease source for lubrication points, reducing external contamination; the transparent cup design allows the operator to visually observe the remaining grease level for timely replenishment and regular maintenance; its simple structure, easy installation, and low cost make it an effective and necessary auxiliary component for maintaining numerous dispersed, low-speed, and non-core lubrication points of equipment and preventing dry friction, jamming, or abnormal wear.
