Spindle S2 AW 15 – Spindle Oil
Product Overview
Synolex Spindle S2 AW 15 is a spindle lubricant for oil-lubricated precision spindles and bearings requiring the ISO VG 15 grade. A spindle must maintain its intended motion while operating within the bearing system temperature and lubrication limits. Oil delivery, viscosity and the bearing arrangement therefore work together. This product is selected for the spindle requirement stated by the machine builder, providing a clear reference for a lubrication point where unnecessarily heavy oil or an unsuitable delivery method can affect operation.

Key Features and Benefits
1. Lubrication for precision rotating contacts
Spindle bearings require lubricant at the working contact while the shaft rotates. Synolex Spindle S2 AW 15 supplies a defined viscosity choice to match that requirement. The correct selection considers the bearing design and speed, keeping the oil matched to the precision mechanism it serves.
2. Attention to friction and temperature
Oil viscosity influences both film formation and resistance to movement. Spindle service requires a balance suited to the machine, rather than simply selecting a thicker grade. Operating temperature is an important observation when checking that the lubricant and delivery arrangement fit the spindle duty.
3. Compatibility with the intended supply method
Spindle oil may be delivered through different machine-specific arrangements. The chosen grade must work with the installed system and reach the bearing in the required quantity. Pumped, metered or other supply methods should follow the original equipment instructions.
4. A clear grade for maintenance control
The ISO VG 15 designation makes the intended viscosity visible in stores and maintenance records. This is useful where a machine shop holds several low-viscosity oils. The exact grade should remain attached to the spindle lubrication point and its dedicated filling equipment.
5. Support for repeatable operating conditions
Keeping the specified oil and delivery settings consistent helps establish a useful spindle operating baseline. Temperature and behaviour can then be compared at similar speed and load. This supports diagnosis without introducing an unnecessary lubricant change into every maintenance assessment.
6. Clean supply to sensitive components
Clean filling and appropriate filtration help keep unwanted particles out of the spindle lubrication path. The oil should be handled as a precision-machine consumable, with covered containers and dedicated transfer equipment suited to the machine service arrangement.
Applications
Select Synolex Spindle S2 AW 15 from the machine lubrication specification, taking account of spindle speed, bearing design and oil-delivery method. A spindle is not necessarily served by the same oil as the machine slideways or hydraulic circuit. Keep these lubrication points separate in service records and use the full product designation when ordering replacement oil.
- Oil-lubricated machine-tool spindles with a matching viscosity requirement.
- Precision bearing circuits specifying the relevant spindle-oil category.
- Approved metered or circulating spindle lubrication arrangements.
- Scheduled replenishment and replacement of the identified spindle lubricant.
Viscosity and Grade Selection
The ISO VG 15 designation identifies the nominal viscosity class at the 40°C reference temperature. It is a grade reference, not a measured typical property for an individual batch and not the maximum operating temperature. This is a relatively low-viscosity grade within industrial oil classifications. It is selected where the equipment needs the corresponding flow and lubrication characteristics. As oil temperature changes, its viscosity changes too. The operating requirement therefore includes both starting conditions and the temperature reached during normal service. Use the current product data sheet to review the actual viscosity and any other properties required for the application. A different series with the same grade can still have a different intended duty. Keep the full product designation when comparing alternatives or placing an order, and use the equipment specification to decide whether a neighbouring grade is appropriate.
Performance in the Application
The spindle lubrication circuit should be understood before choosing an oil. The oil may serve one bearing group or several contacts with different positions and feed restrictions. Delivery can change if a metering point is blocked even while the reservoir appears full. Establish the required quantity and verify it through the procedure provided for the machine. When reviewing another product, compare the viscosity classification itself because a commercial product number is not always its ISO grade. The operating record should identify both the oil and the spindle conditions so that later changes can be assessed on a consistent basis.
Handling and Service
Use clean, dedicated transfer tools and protect filling points from machining debris. Maintain the required oil level or feed setting. After servicing, check operation under the machine prescribed start-up procedure and observe temperature at comparable speed. Investigate changes in vibration, noise or heat alongside bearing condition, balance and the oil supply. Do not increase viscosity as a routine response to a mechanical fault.
Store the product in its original labelled container in a clean, covered area. Close the container after dispensing and use dedicated, clean transfer equipment. Protect the product from water and debris and keep batch identification legible. Follow the safety data sheet for handling and spill management, and manage used product through the applicable collection arrangements.
Why Choose This Product?
Choose Synolex Spindle S2 AW 15 for precision spindles whose oil specification calls for this grade. Its application is centred on lubrication of rotating bearing contacts with careful control of viscosity and supply. This supports a focused approach to spindle temperature and operating consistency within the machine builder requirements.
Product Selection and Ordering
For product selection or an order, provide the complete Synolex designation, the equipment or process application and the quantity required. Where a replacement is being considered, include the current lubricant name and the relevant equipment requirement. This allows the proposed product to be compared on application and documented properties. The current technical data sheet governs numerical specifications and any formal approvals. The comparison section below retains the product references and their qualifications, so that a potential alternative can be reviewed in its proper technical context.
Similar Products (Equivalent Matching)
The entries below support technical comparison. A documented comparator does not establish an automatically approved replacement. Conditional alternatives require the stated differences to be resolved. A family-level lead does not verify the exact grade, and the absence of a verified entry does not mean that no product exists in the market.
