Why Choose a 304 Stainless Steel Raceway?
- Corrosion Resistance: 304 stainless steel withstands rust from rain, seawater splash, and chemical fumes – ideal for outdoor installations like solar trackers, port cranes, and marine equipment.
- Durability in Harsh Environments: The raceway remains dimensionally stable under UV exposure, ozone, and temperature fluctuations (-40°C to +120°C).
- Low Maintenance: Properly sealed and lubricated, this bearing requires minimal attention over its service life, reducing operational costs.
- Custom Flexibility: As a custom product, we can adjust raceway hardness, surface finish, and internal geometry to optimize load distribution for your specific application.
- Compliance with International Standards: Our manufacturing process follows ISO9001 and ISO16949 quality systems, ensuring consistent performance and traceability.
Benefits for Your Application
- Longer operational life compared to standard carbon steel bearings in corrosive environments, reducing replacement frequency.
- Smooth, low-torque rotation even under heavy loads – suitable for precision positioning in solar tracking or radar platforms.
- Sealed design prevents ingress of dirt, water, and debris – especially important for outdoor construction and agricultural machinery.
- Gear integration available – can be supplied with internal or external teeth for direct drive systems.
- Fast quotation and prototype delivery – we support rapid customization (typically 2-4 weeks for non-standard orders).

Frequently Asked Questions (FAQ)
-
What is the minimum order quantity (MOQ) for custom slewing bearings?
Our MOQ is generally 1 piece for non-standard dimensions. We welcome small-scale prototypes for testing. -
Can you supply the bearing with external gear teeth?
Yes, both internal and external gear teeth are available. Please specify module, number of teeth, and pressure angle. -
What raw material certificates do you provide for the 304 stainless steel raceway?
We can provide mill test certificates (MTC) verifying the chemical composition and mechanical properties of the stainless steel. -
How do you seal the bearing against water and dust?
Our standard double-lip nitrile seal provides IP66-level protection. For submerged or heavy washdown applications, we recommend PTFE seals or labyrinth seals (optional). -
What is the typical lead time for a custom bearing?
Standard custom orders (without complex machining) take 15–25 working days. Urgent orders can be expedited with an extra charge. -
Do you test the bearing before shipment?
Yes, every bearing undergoes rotational torque test, runout measurement, and leak test (if sealed). A test report is included. -
Can the bearing operate in high-temperature outdoor conditions?
The standard design is for -40°C to +120°C. For higher temperatures (up to 250°C), we can change the raceway material to 316 stainless steel and use high-temperature grease. -
Do you offer warranty?
We offer a 12-month warranty from the date of shipment against manufacturing defects. Extended warranty is negotiable.
