Stainless Steel Bearings
-- Steady & Reliable Manufacturer --
Brief Description
Full stainless steel bearings (440C, 304, or 316 grade) offering exceptional resistance to moisture, corrosion, and harsh chemicals, essential for washdown, marine, and humid environments.
Introduction
In environments exposed to water, cleaning agents, or corrosive chemicals, standard chrome steel bearings quickly rust and fail. Our Stainless Steel Bearings (SSBs) provide a reliable, hygienic solution. Most commonly made from AISI 440C for high hardness and load capacity, or AISI 304/316 for superior chemical resistance, SSBs are ideal for food, marine, and pharmaceutical applications. We combine the corrosion-resistant steel with enhanced sealing systems and, where necessary, food-grade (H1) grease, ensuring extended operational life where moisture or frequent washing is unavoidable.

Specification Standards
| Key Feature | Material Grade | NSB Offering |
|---|---|---|
| Corrosion Resistance | AISI 440C (Hardest) or 304/316 (Most Chemical Resistant) | Excellent performance in wet and caustic environments. |
| Sealing System | 2RS (Contact Seals) Standard | Crucial for keeping moisture out and lubricant in. |
| Lubrication | Food Grade (H1) or Synthetic Water-Resistant Grease | Protects against internal corrosion and water washout. |
| Design Focus | Deep Groove Ball Bearings (DGBB) | Most commonly produced type due to versatility. |
| Load Reduction | Lower Dynamic Load Rating than Chrome Steel | A necessary compromise due to material differences. |
Applications
