Upgrade your mechanical assemblies with this precision-engineered 304 Stainless Steel Rod End Bearing by JARBLUE. Available in a wide range of metric thread sizes — 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, 18mm, 20mm, 22mm, and 25mm — and in both Male (SA/PHSA) and Female (SI/POSA) configurations with right-hand and left-hand thread options (TK Series). Designed for demanding industrial, automotive, agricultural, and DIY applications where corrosion resistance and structural reliability are essential.

Made in Mainland China.

Why Choose 304 Stainless Steel?

I. Superior Material Advantages

• Excellent Corrosion Resistance: Contains 18% chromium and 8% nickel, forming a dense chromium oxide passivation film on the surface. Resistant to water, moisture, steam, weak acids, alkalis, and salt spray — ideal for humid, outdoor, food processing, chemical, and marine environments where ordinary bearing steel would corrode quickly.
• Hygienic, Eco-Friendly & Easy to Clean: The smooth, non-porous surface meets food and pharmaceutical grade hygiene standards. Withstands high-temperature cleaning, steam sterilization, and disinfectant wiping without contaminating surrounding media.
• Non-Magnetic / Weakly Magnetic: Essentially non-magnetic in its annealed state (may show weak magnetism after cold working). Suitable for use near magnetic-field-sensitive equipment such as precision electronics and instruments.
• Outstanding Toughness & Machinability: High toughness with excellent impact resistance and no tendency for brittle fracture. Easy to turn and polish, making it the ideal choice for precision joint structures.

Frequently Asked Questions

Q: What thread options are available for these rod end bearings?

A: These 304 stainless steel rod end bearings are available in both right-hand and left-hand metric threads across the TK Series. Both Male (SA/PHSA) and Female (SI/POSA) configurations are offered in sizes from 5mm up to 25mm. Please select your required thread direction, gender, and size from the product options at checkout.

Q: Are these rod end bearings suitable for outdoor or marine environments?

A: Yes. The 304 stainless steel construction with a nickel coating provides excellent resistance to water, salt spray, moisture, and mild chemicals, making these bearings well-suited for outdoor, marine, and other corrosion-prone environments where standard carbon steel bearings would degrade quickly.

Q: How many pieces are included in one order?

A: Each order includes 1 piece of the rod end bearing in your selected size and thread configuration. If you need multiple pieces, simply adjust the quantity before adding to your cart.

Q: What does the Ra 1.6 surface roughness specification mean?

A: Ra 1.6 is a standard industrial surface finish measurement indicating a smooth, finely machined surface. This level of finish ensures precise fit, reduced friction in the joint, and easier cleaning — particularly important for food processing or pharmaceutical machinery applications.
