ROYCO 44 Lubricant: Uses, Comparison and MRO Buying Guide
ROYCO 44 is a LANXESS heavy-duty lubricant described as having a consistent texture and electrical conductivity for aerospace and industrial use. For aircraft MRO, the product name is a starting point for procurement—not enough information by itself to establish suitability for a particular component or maintenance task.
Key Takeaways
- ROYCO 44 is listed as a lubricant, with heavy-duty formulation, consistent texture, and electrical conductivity among its stated characteristics.
- Electrical conductivity does not, by itself, establish that a lubricant is suitable for an electrical contact or bonding application.
- ROYCO 44, ROYCO 43, and ROYCO 1MS are distinct products; their names are not interchangeable purchase instructions.
- A useful request for quote states the exact part number, required quantity, packaging requirement, and any documentation the buyer needs.
What Is ROYCO 44?
The ROYCO 44 lubricant product listing identifies the part number as ROYCO-44 and the brand as LANXESS. It describes a heavy-duty lubricant with a consistent texture and electrical conductivity. Those are useful identifying details, but the listing does not state its base fluid, thickener, operating-temperature limits, shelf life, or approval for a specific aircraft application.
In purchasing terms, “ROYCO 44” names the product, while “ROYCO-44” is the part-number format shown on the listing. Buyers should preserve the complete identifier when requesting a quote or checking an incoming item. A similar ROYCO name may refer to a different formulation and use case.
How Does ROYCO 44 Compare With Other ROYCO Lubricants?
The ROYCO range includes products described as greases, oils, and other lubricants. A shared brand name does not make them substitutes. The table below compares only characteristics stated in the supplied product descriptions.
| Product | Listed type | Distinguishing description | Procurement implication |
|---|---|---|---|
| ROYCO-44 | Lubricant | Heavy-duty formula, consistent texture, and electrical conductivity | Request the exact product when ROYCO 44 is specified. |
| ROYCO-43 | Grease | Lithium-soap-thickened synthetic-oil grease described for uses including elastomer-to-metal interfaces in pneumatic systems and aircraft grommets | Do not treat the adjacent number as a revised or equivalent version of ROYCO 44. |
| ROYCO-1MS | Lubricant | Combines microfine powdered molybdenum disulfide and technical-grade petrolatum; described as an electrical conductor | Conductivity alone does not establish equivalence to ROYCO 44. |
| ROYCO-81MS | Lubricant | High-temperature semi-fluid lubricant described for metal-on-metal applications | Its different formulation and stated uses call for a separate product selection. |
For example, ROYCO 43 grease has a stated lithium-soap-thickened synthetic-oil formulation; the supplied ROYCO 44 description does not give an equivalent formulation detail. Likewise, ROYCO 1MS lubricant is described as electrically conductive, but that single shared characteristic does not show that it can replace ROYCO 44. Compare the full product identification and intended application rather than selecting by number or one advertised property.
What Should Engineers Verify Before Specifying It?
Start with the maintenance task: identify the component, lubrication point, and reason lubricant is needed. Then match the required product identification against the available manufacturer information. If the task calls for a particular material or an approved alternative, record that requirement explicitly for purchasing rather than passing along a general description such as “conductive grease.”
- Product identity: Confirm whether the instruction calls for ROYCO 44 by name or part number.
- Application details: Identify the surface or assembly and the intended function of the lubricant.
- Material characteristics: Check the current product data for the formulation and properties relevant to that application; do not infer unspecified values from a short catalog description.
- Electrical context: If conductivity matters, define what the maintenance instruction actually requires. A conductivity claim alone does not describe contact resistance, bonding performance, or suitability for a particular electrical assembly.
For aircraft work, confirm the applicable approval or material callout in the aircraft maintenance documentation and follow the manufacturer's current data sheet for product use. Do not substitute another lubricant based solely on a similar name, appearance, or stated characteristic; resolve any proposed alternative through the applicable airworthiness and maintenance approval process.
How Should an MRO Buyer Request ROYCO 44?
A precise request helps the supplier identify the intended item and helps the buyer evaluate the response. Include the part number as listed, the quantity and preferred unit of measure, any packaging requirement, the delivery destination, and the documentation required by the purchase order. If an internal material number is used, include it alongside—not instead of—the manufacturer product identification.
For example: “Please quote LANXESS ROYCO-44 lubricant, quantity 6 containers. State the container size offered and identify any product documentation available with the quote. Reference our internal requisition MRO-2716.” The requisition number in this example is illustrative, not a ROYCO part number.
If the request originates from a technician's note reading only “Royco conductive lubricant,” obtain clarification before placing the order. More than one product description mentions electrical conductivity, and the maintenance requirement may call for a specific product. The buyer's job is to preserve that distinction through the quote, purchase order, and receiving process.
What Information Belongs in the Receiving Check?
When material arrives, compare the product identifier and container description with the purchase order. Check that the delivered quantity and package size match what was accepted on the quote. Record any lot or batch identification shown on the packaging according to the organization's receiving procedure, and match accompanying documents to the delivered material.
This check is especially helpful when a purchasing system abbreviates descriptions. “ROYCO lubricant” is less specific than “ROYCO-44,” and a nearby product number can represent a different material. Retaining the exact identifier throughout the transaction reduces ambiguity for stores personnel and the maintenance team that requested it.

Frequently Asked Questions
What type of product is ROYCO 44?
ROYCO 44 is listed as a LANXESS lubricant. Its supplied product description calls it heavy-duty and notes a consistent texture and electrical conductivity.
Is ROYCO 44 the same as ROYCO 43?
No. They have different product identifiers, and ROYCO 43 is specifically described as a lithium-soap-thickened synthetic-oil grease. Do not use the numbers interchangeably on a purchase request.
Does ROYCO 44's electrical conductivity make it suitable for electrical contacts?
Not necessarily. The stated conductivity is a product characteristic, but the supplied description does not establish suitability for a particular contact, connector, or bonding task.
Can ROYCO 1MS replace ROYCO 44?
The supplied information does not establish that the products are interchangeable. ROYCO 1MS has a stated molybdenum-disulfide-and-petrolatum composition; use the product identified for the maintenance task.
What part number should I put on a ROYCO 44 quote request?
Use ROYCO-44, the part-number format shown on the product listing. Add the quantity and any packaging or documentation requirements needed for your order.
