Large Sized Stainless Steel Bearings
SPB-USA, a division of Solve Industrial Motion Group, supplies large sized stainless steel bearings manufactured by EZO, a trusted name in high-precision components. These bearings are built to support demanding applications where durability, corrosion resistance, and consistent performance are essential. Available in Open, Shielded, and Sealed configurations, these large stainless steel ball bearings serve industries requiring reliability under heavy loads and harsh environments.
What Defines a Large Stainless Steel Ball Bearing?
Large stainless steel ball bearings generally refer to deep groove radial ball bearings with bore sizes ranging from 10 mm up to 90 mm or more. These bearings are crafted from 440C stainless steel, which offers a combination of hardness, strength, and corrosion resistance. They are suitable for high-speed operations, moderate to heavy radial loads, and exposure to moisture, cleaning agents, or chemicals.
Open Large Size Stainless Steel Ball Bearings
Open bearings are manufactured without shields or seals, leaving the rolling elements visible. This design provides minimal resistance and allows easy access for inspection, lubrication, and maintenance. Open large size stainless steel ball bearings are commonly used in environments where external lubrication is controlled, or where contaminants are not a concern.
Examples include the 6000H (also known as SS6000 Open), 6200H (also known as SS6200 Open) and 6300H (also known as SS6300 Open) series. These bearings perform well in clean or temperature-controlled systems such as food processing equipment with centralized lubrication, low-contamination industrial assemblies, and test machinery that requires frequent observation.
Shielded Large Size Stainless Steel Ball Bearings
Shielded bearings feature one or two metal shields (Z or ZZ) that help protect the bearing interior from debris, while still allowing grease retention. These are suitable for environments where some exposure to dust or splashing fluids occurs, but where full sealing is not necessary.
The SS6200ZZ and SS6300ZZ are common shielded options. They are frequently used in conveyor systems, automated machinery, electric motors, and other industrial equipment that benefits from reduced maintenance cycles and controlled contamination levels.
Sealed Large Size Stainless Steel Ball Bearings
Sealed Bearings feature two rubber seals (-2RS) that help protect the bearing interior from debris, while still allowing grease retention. These are suitable for environments where exposure to dust or splashing fluids occurs, and where the full contact seal will not impact performance; typically applications with lower speeds.
The 6000H-2RS (also known as SS6000 2RS), 6200H-2RS (also known as SS6200 2RS) and 6300H-2RS (also known as SS6300 2RS) are common sealed options. They are frequently used in conveyor systems, automated machinery, electric motors, and other industrial equipment that benefits from reduced maintenance cycles and controlled contamination levels.
Shielded & Sealed Stainless Steel Bearings are pre-lubricated high quality multipurpose grease that can be used in a wide variety of applications. They can also be ordered with an FDA approved Food Grade grease for applications with hygienic requirements.
Where Large Stainless Steel Bearings Are Used
Large stainless steel ball bearings are used in equipment exposed to moisture, chemicals, or washdown procedures. Their resistance to corrosion and ability to maintain performance under load make them suitable across several industries.
Typical applications include:
- Food and beverage processing equipment – mixers, conveyors, and filling machines that require hygienic, corrosion-resistant components
- Pharmaceutical and medical manufacturing systems – cleanroom conveyors, capsule filling machines, and inspection stations
- Marine equipment – winches, thrusters, and pumps exposed to saltwater environments
- Chemical processing equipment – agitators, valve actuators, and centrifuges that encounter corrosive fluids
- Automated washdown machinery – spray systems and belt drives in sanitation zones
- Industrial electric motors and gearboxes – where durability and resistance to contamination are required
- Packaging machinery – especially in wet or high-humidity settings
Open bearings are often selected for equipment that includes a centralized lubrication system or frequent cleaning, while shielded bearings are commonly used where debris or fluid exposure is present but not excessive.
