SS6805 Stainless Steel Bearing

Category：

SS6800 Series Stainless Steel Bearings

SS6805 stainless steel bearings are manufactured with high-performance stainless steel and precision machining, providing improved material strength, dimensional accuracy, and quality stability compared with standard 6805 bearings. Their corrosion-resistant, rust-resistant, and wear-resistant design ensures reliable performance in harsh or sanitary environments. These SS6805 stainless steel bearings are available in open, metal shield (ZZ), and rubber seal (2RS) configurations, allowing users to select the ideal sealing structure for humidity, dust, or chemical exposure. Each SS6805 bearing is filled with high-temperature, long-life grease that remains stable from –60°C to +300°C, ensuring consistent speed and low noise under demanding conditions. This makes SS6805 bearings widely used in food processing equipment, medical devices, pharmaceutical machinery, and other precision applications that require clean, corrosion-resistant, and reliable operation.

SS6805 Stainless Steel Bearing: Three Superior Properties

The SS6805 stainless steel bearing is engineered for demanding environments that require corrosion resistance, hygiene compliance, and magnetic-free operation. With 304/440C stainless steel construction, advanced sealing options (open / ZZ / 2RS), and stable low-noise performance, it provides reliable operation for food machinery, medical devices, laboratory instruments, and precision equipment.
(1) Superior Corrosion Resistance for Harsh Environments: Built with 304 or 440C stainless steel, the SS6805 bearing resists moisture, chemicals, and acidic or alkaline environments. This high level of corrosion protection prevents rust, reduces the risk of bearing seizure, and extends service life in humid, washdown, or chemically exposed conditions. Ideal for food processing and sanitary machinery.
(2) High-Temperature Cleaning & Sterilization Compatible: The smooth stainless steel surface and stable material structure withstand high-pressure washdown, chemical disinfection, and high-temperature steam sterilization. SS6805 bearings help equipment meet strict hygiene standards in the food, medical, and pharmaceutical industries while avoiding cleaning blind spots and eliminating contamination risks.
(3) Non-Magnetic Design for Precision-Critical Applications: Manufactured with non-magnetic materials, the SS6805 bearing eliminates magnetic interference that can disrupt sensitive equipment. This makes it suitable for medical diagnostic devices, laboratory analyzers, precision instruments, and environments near magnetic fields, ensuring stable operation and accurate measurement results.

Material Options for SS6805 Stainless Steel Bearings

To meet different operating environments and hygiene standards, SS6805 stainless steel bearings are available in multiple material grades. Each material provides specific advantages in strength, corrosion resistance, and temperature tolerance.
(1) AISI 440C – High-Strength Stainless Steel for Precision Performance
AISI 440C offers high hardness, excellent wear resistance, and strong corrosion resistance, making it the preferred choice for high-performance SS6805 bearings.
Best for: high-speed motors, CNC spindles, medical devices, robotics, and automation systems requiring stable precision.
(2) AISI 420 – Economical Rust-Resistant Stainless Steel
AISI 420 provides moderate hardness and basic wear resistance, suitable for lighter loads and shorter duty cycles.
Best for: general industrial machinery, transmission parts, tools, and equipment with standard rust-prevention requirements.
(3) AISI 304 – Hygienic Corrosion-Resistant Stainless Steel
AISI 304 offers excellent chemical stability and corrosion resistance, especially in clean or washdown areas.
Best for: food processing equipment, household appliances, packaging lines, and applications requiring frequent cleaning.
(4) AISI 316 – Premium Stainless Steel for Highly Corrosive Environments
AISI 316 contains molybdenum for enhanced resistance against acids, alkalis, and salt spray.
Best for: pharmaceutical systems, marine machinery, chemical pumps, and washdown equipment exposed to aggressive media.

SS6805 Stainless Steel Bearing: Frequently Asked Questions

Q1:Why choose SS6805 stainless steel instead of a standard 6805?
A1: SS6805 uses corrosion-resistant stainless steel, offering longer life in humid, chemical, or sanitary environments. It keeps the same 25×37×7 mm thin-section size and provides stable, low-noise running for food, medical, and lab equipment.
Q2: Can SS6805 handle high speed and load?
A2: Yes. It supports high-speed rotation, radial loads, and light axial loads. Options like C3/C4 clearance, ZZ/2RS seals, or food-grade grease improve durability in pumps, motors, and compact precision devices.
Q3: What customization options are available?
A3: We offer OEM customization including material grade, sealing (open/ZZ/2RS), grease type, clearance, noise level (Z3–Z5), and laser marking. These upgrades solve problems like rusting, short lifespan, and noise in demanding applications.
