The 500 ml automatic rock drill oiler is a dedicated lubrication device engineered for multi-machine lubrication in mining and construction sites. It delivers precise oil-air atomization to protect pistons, rotating sleeves, and drill rods from friction and corrosion during rock drilling operations. Manufactured under standardized quality management processes, it is compatible with mainstream pneumatic rock drill models, serving as a supporting component for commercial procurement of mining and construction equipment fleets.
This rock drill oil injector operates through a pressure-driven oil-air mixing structure. As equipment runs, pressurized gas enters the inner cavity of the shell through the windward hole of the oil valve, applying pressure directly to the oil surface. The oil outlet hole, positioned perpendicular to the gas flow direction, creates a pressure differential that discharges lubricating oil into the conveying pipeline. The oil is atomized into fine mist within the compressed gas pipeline, delivering continuous and uniform lubrication to moving parts of the rock drill and air leg. This structure adapts to the high-speed dynamic operation of internal rock drill components.
The oil injector supports adjustable lubrication flow, with a recommended operating rate of 2.5-3 ml per minute. Operators can adjust the oil output by pulling the oil valve handle to match specific equipment operation requirements and rock formation conditions. The unit adopts a transparent body design, which allows operators to monitor remaining oil levels directly without disassembly. Optimal lubrication levels can be verified by the presence of visible oil mist in the drill’s exhaust, enabling straightforward on-site adjustment.
This series of oil injectors is designed to lubricate up to three rock drills simultaneously, which supports centralized lubrication management for multi-machine work sites. This configuration reduces on-site equipment setup steps and supports consistent lubrication standards across a fleet of rock drilling units, helping to streamline on-site equipment management workflows.

To maintain consistent equipment performance, set the oil flow rate within the 2.5-3 ml per minute range during routine operation. Visible oil mist in the drill exhaust indicates appropriate lubrication levels. The unit is designed for use with liquid lubricating oil formulated for pneumatic drilling equipment, and regular oil level checks support uninterrupted on-site operations.
Grease lubrication is not compatible with this oil injector. Grease may clog internal holes and obstruct gas flow, leading to insufficient lubrication of the drill head and air leg, reduced operational efficiency, and accelerated wear of components. Regular inspection of pipeline connections and oil valve function supports stable lubrication performance and extends the service life of both the oil injector and connected rock drills.
This rock drill oil injector is produced by Xianghe Kaituo Mining Machinery Co., Ltd., with factory-direct supply for industrial clients. The production facility operates under an ISO9001:2015 compliant quality management system and has passed SGS factory audits (Report No.: QIP-ASI246873). The enterprise maintains stock of spare parts for oil injectors and supporting rock drill components. For order fulfillment, in-stock items are scheduled for delivery within 15 days of order confirmation, while larger volume orders may require up to 30 days for production and shipment. The enterprise supports multiple freight modes, including sea freight, land transport for neighboring landlocked countries, and air freight for urgent small parts orders, with delivery to designated warehouses available upon request.
The adjustable flow rate of this 500ml rock drill oil injector ranges from 2.5 ml to 3 ml per minute. Operators can adjust the flow via the oil valve handle based on on-site operation requirements and equipment conditions.
This oil injector is compatible with all mainstream pneumatic rock drill models, including YT27, YT28, YT29A, and S250 series units. Customers can consult the supply team for compatibility confirmation of other models.
One unit of this rock drill oil injector is designed to lubricate up to three rock drills simultaneously, supporting centralized lubrication management for multi-machine work sites.
For in-stock units, delivery is arranged within 15 days of order confirmation. For larger volume orders that require additional production, the delivery cycle may extend up to 30 days. Specific schedules are confirmed upon formal order placement.
