OEM & Custom Bearing Services
Standard bearing models cover a wide range of industrial applications, but some equipment requires specific dimensions, internal clearance, sealing, lubrication, precision, marking, or packaging.
We provide OEM and custom bearing supply for ZWZ industrial bearings, including non-standard specifications, application-specific configurations, private labeling, and custom packaging. Custom requirements are reviewed according to the bearing type, technical specifications, quantity, application conditions, and supply feasibility.
What Can Be Customized?
Custom requirements can be reviewed against an existing bearing model, technical drawing, bearing sample, or application data.
Non-Standard Dimensions
When a standard bearing does not match the shaft or housing, the required dimensions can be reviewed, including:
- Bore diameter
- Outside diameter
- Bearing width
- Mounting dimensions
- Other dimensional requirements
A 2D drawing or complete dimensional specification is recommended for non-standard dimensions.
Internal Clearance
Internal clearance should be selected according to the actual operating conditions.
Common options include:
- C2
- C0 / Normal
- C3
- C4
Clearance requirements can be affected by operating temperature, interference fit, rotational speed, and application conditions.
Precision Grade
Precision requirements can be specified according to the equipment's running accuracy and operating conditions.
Common precision grades include:
- P0
- P6
- P5
- P4
The appropriate grade should be determined by the required running accuracy, speed, vibration level, and equipment tolerance.
Sealing and Shielding
Sealing or shielding can be reviewed according to contamination, moisture, speed, friction, and lubrication requirements.
Typical configurations include:
- Open
- ZZ / 2Z metal shields
- 2RS contact seals
- Other configurations subject to technical review
Lubrication
Lubrication requirements can be reviewed according to operating conditions.
Depending on the bearing type and application, options may include:
- Standard industrial grease
- High-temperature grease
- Special grease
- Oil lubrication
For special lubrication requirements, provide the operating temperature, speed, load, working environment, and expected service conditions.
When Is a Custom Bearing Required?
A custom or non-standard bearing may be required when a standard catalog bearing does not match the equipment or operating conditions.
Typical situations include:
- The standard bore or outside diameter does not match the equipment.
- The existing bearing uses a non-standard internal clearance.
- A specific seal or shield configuration is required.
- The application requires a particular precision grade.
- Different lubrication is required for the operating temperature or speed.
- An existing bearing is obsolete or difficult to source.
- The customer requires private labeling or dedicated packaging.
- Multiple bearing specifications need to be supplied under an OEM program.
The required configuration should be determined from the actual operating conditions rather than from the bearing name alone.

Custom Bearing Supply Process
Requirement Review
Submit the bearing model, drawing, sample, dimensional data, or application requirements.
Technical Confirmation
The required configuration is reviewed against dimensions, load, speed, clearance, precision, sealing, lubrication, and other relevant operating conditions.
Quotation
After the specification is confirmed, the quotation can be prepared according to the agreed product configuration, quantity, packaging, and delivery requirements.
Sample or Trial Order
For new or modified requirements, a sample or small trial order can be arranged when applicable. Sample support and small-batch orders are stated as available services.
Inspection
The confirmed specification is used for the order. Published quality-control procedures for ball bearings include:
- Dimensional inspection
- Hardness testing
- Noise testing
- Vibration testing
- Rotation testing
Inspection requirements and applicable documentation can be confirmed with the order.
Packaging and Shipment
Products are packed according to the confirmed packaging requirements and prepared for export shipment. Export documentation and logistics tracking are available as part of the stated supply service.
Quality, Certification & Supply Evidence
For OEM and custom orders, the technical specification should be confirmed before order fulfillment.
Depending on the product and order requirements, documentation may include:
- Product specifications
- Dimensional information
- Inspection information
- Packing details
- Shipping documents
- Applicable quality certificates
The company states that it has independent import and export rights and supplies ZWZ industrial bearings to international customers.
Published management and quality credentials include:
- ISO 9001
- ISO 14001
- ISO 50001
- IRIS Silver certification by TÜV Rheinland
Where applicable, certification and authorization documents can be provided for buyer review.
ZWZ Authorized Distribution
The company identifies itself as an authorized ZWZ distributor. For procurement and supplier verification, buyers can request applicable authorization documentation and confirm the relevant product scope.
Inspection Evidence
For products subject to inspection, applicable inspection records or technical documentation can be discussed according to the product and order requirements.
Where available, buyers may request relevant product, inspection, certification, or packaging documentation during the quotation and order-confirmation process.
Custom bearing requirements can arise across a range of industrial equipment, including:
Electric motors
Metallurgical equipment
Pumps and compressors
Cement machinery
Gearboxes
Agricultural machinery
Machine tools
Automotive components
Conveyors
Industrial automation
Mining equipment
Power transmission equipment
The required bearing configuration should be determined from the actual operating conditions.
Shaft and housing dimensions, radial and axial loads, rotational speed, temperature, contamination, lubrication, and running accuracy can all affect bearing selection.
Custom Bearing Replacement
When replacing an existing bearing, the original part number is useful but may not always be sufficient.
For a replacement review, provide:
Original bearing number Bearing markings Bore diameter Outside diameter Width Seal or shield type Internal clearance, if known Application Operating speed Operating temperature Load conditions Photos or an existing bearing sample
For obsolete or difficult-to-source bearings, a drawing or physical sample can help confirm the required dimensions and configuration.
The replacement specification should be confirmed before an order is placed.

Request a Custom Bearing Quote
Send us your bearing model, technical drawing, existing sample, or application requirements.
For a faster quotation, include:
Bearing type + model/dimensions + quantity + application + speed + load + temperature + clearance + sealing + lubrication + packaging requirements
If you are replacing an existing bearing, a photo showing the bearing marking, dimensional data, or a physical sample can help with identification and technical review.
