Why NBR 70 ShA for Industrial Sealing?

NBR, nitrile butadiene rubber, is one of the most commonly used elastomers in industrial sealing technology. Its key advantage is good resistance to many mineral oils and lubricating greases.

The 70 Shore A hardness is a widely used specification for general-purpose O-rings. It provides a practical balance between elasticity, mechanical stability and the ability of the elastomer to conform to the sealing groove.

For this reason, NBR 70 ShA O-rings are commonly used in industrial machinery, hydraulic systems, pneumatic equipment and mechanical assemblies.

Bulk 1000 pcs for Serial Production

This 1000 pcs bulk pack is specifically intended for companies with recurring demand for 22x2 mm O-rings.

Typical users include:

• industrial manufacturers
• OEM assembly plants
• machinery manufacturers
• maintenance departments
• MRO suppliers
• technical service companies
• industrial distributors
• resellers

Keeping 1000 identical O-rings in stock can reduce the need for frequent small orders and simplify material availability for repetitive assembly or maintenance operations.

Applications of 22x2 mm O-Rings

The 22x2 mm NBR O-ring can be used in appropriately designed:

• hydraulic systems
• pneumatic systems
• valves
• pumps
• fittings
• industrial machinery
• oil-lubricated assemblies
• production equipment
• OEM components
• maintenance and repair operations

The exact suitability should always be verified according to groove geometry, pressure, temperature, operating medium and whether the sealing point is static or dynamic.

Hydraulic Applications

NBR is extensively used in hydraulic sealing systems, particularly with compatible mineral oil-based hydraulic fluids.

A 22x2 mm O-ring can provide compact sealing between correctly designed mating components in valves, manifolds, fittings and other hydraulic assemblies.

For high-pressure applications, extrusion gap, groove geometry and the possible requirement for backup rings must also be considered.

Pneumatic Applications

NBR O-rings are also widely used in pneumatic systems.

Depending on the design of the sealing assembly, they can be used in valves, pneumatic components, connectors and other equipment requiring an elastomeric sealing element.

Correct lubrication and surface condition are particularly important where an O-ring operates dynamically.

Economic Benefits of a 1000 pcs Bulk Pack

Purchasing 1000 O-rings in one bulk package is intended for B2B users who require continuous access to the same sealing size.

A bulk package can help:

• reduce purchasing frequency
• maintain production stock
• supply multiple maintenance stations
• support repetitive OEM assembly
• simplify internal logistics
• reduce the risk of shortages during planned maintenance
• maintain safety stock for recurring repairs

For companies regularly consuming 22x2 mm O-rings, bulk purchasing also simplifies inventory planning.

OEM and Production Line Supply

The 1000 pcs variant is particularly suitable for OEM and serial production environments.

A standardized bulk supply can be allocated directly to production stations or maintained as central warehouse stock.

For recurring production, the required material, hardness, dimensions and technical specification should remain consistent with the approved component specification.

MRO and Maintenance Stock

O-rings are small components, but their absence can delay machinery repair and restart.

Keeping NBR 22x2 70 ShA O-rings as MRO warehouse stock provides immediate access to replacement seals during scheduled maintenance and unplanned repairs.

This makes the 1000 pcs package particularly relevant for factories, workshops and maintenance departments where the same dimension is repeatedly consumed.

Storage of NBR O-Rings

Bulk O-rings intended for gradual consumption should be stored under conditions that minimize elastomer ageing.

Protect the seals from:

• direct sunlight
• UV radiation
• excessive heat
• ozone sources
• aggressive chemicals
• unnecessary deformation during storage

Correct warehouse storage is especially important when a 1000 pcs package is intended to supply production or maintenance operations over an extended period.

NBR 22x2 70 ShA for B2B Supply

This bulk variant is positioned specifically for:

OEM: repetitive component assembly
MRO: machinery maintenance and repair
Production: regular consumption on assembly lines
Maintenance: replacement sealing stock
Resellers: industrial distribution inventory
Warehouses: safety stock for technical departments

The 1000 pcs quantity clearly distinguishes this product as a bulk industrial supply option rather than a small-quantity maintenance package.

Frequently Asked Questions by Engineers

What is the outside diameter of a 22x2 mm O-ring?
The nominal outside diameter is approximately 26 mm, calculated as the 22 mm inside diameter plus twice the 2 mm cross-section.

What does 70 ShA mean for this O-ring?
70 ShA means the elastomer has a nominal hardness of 70 Shore A, a commonly used hardness for general industrial O-ring applications.

Is NBR 22x2 suitable for hydraulic oil?
NBR is commonly compatible with many mineral oil-based hydraulic fluids. Compatibility should still be verified for the exact fluid and operating temperature.

Why choose a 1000 pcs bulk pack?
It is intended for companies with recurring consumption, including OEM production, MRO, industrial maintenance and warehouse replenishment.

Can the 22x2 O-ring be used in pneumatic systems?
Yes, when the dimensions, pressure, groove design and operating conditions correspond to the application.

Is NBR suitable for all fuels and chemicals?
No. Chemical compatibility depends on the exact medium, concentration and temperature. FKM, EPDM or another elastomer may be required for incompatible media.

How should a bulk stock of NBR O-rings be stored?
Store them in a dry, protected environment away from sunlight, UV radiation, excessive heat, ozone and aggressive chemicals.
