• Shielded (Z / ZZ)
• Sealed (RS / 2RS)
• Custom sealing systems
• Labyrinth seals (for heavy-duty industrial use)

Custom seals can significantly extend bearing life in harsh conditions.

7. Lubrication Requirements

Specify lubrication type:

• Standard grease
• High-temperature grease
• Food-grade grease
• Oil lubrication
• Long-life sealed lubrication
• Dry lubrication for special environments

Correct lubrication can dramatically improve performance.

8. Tolerance and Precision Grade

Precision levels may include:

• P0 (standard)
• P6 (industrial)
• P5 / P4 (high-precision)
• ABEC ratings for American markets

High-precision bearings are necessary for motors, spindles, robotics, and CNC equipment.

9. Quantity and Order Frequency

Manufacturers need to know:

• Expected order quantity
• Frequency (monthly, quarterly, yearly)
• Whether long-term contracts are required

Larger and recurring orders usually receive better pricing.

10. Branding and Packaging Requirements

Many customers request:

• Private logo engraving

• Custom labels
• QC certificates with company branding
• Barcode or QR labeling

This is useful for distributors and resellers building their own brand.

How the Custom Bearing Ordering Process Works

Custom bearing production generally follows several steps. Understanding this workflow helps you plan better and prevent delays.

Step 1: Submit Your Specifications or Drawings

Provide either:

1. A detailed drawing (CAD preferred)
2. A sample bearing
3. A list of specifications
4. Clear photos and measurements

Manufacturers will use this information to confirm feasibility.

Step 2: Engineering Evaluation

The manufacturer’s engineering team will:

• Verify load calculations
• Confirm appropriate materials
• Recommend changes if needed
• Evaluate design for manufacturability
• Provide feedback on performance expectations

This step ensures the final product meets your needs safely and efficiently.

Step 3: Quotation

The quotation typically includes:

• Unit price
• Minimum order quantity (MOQ)
• Material and design details
• Lead time for sampling and mass production
• Packaging details
• Payment terms
• Shipping costs (if applicable)

Custom bearings may have higher MOQ due to unique tooling requirements.

Step 4: Sample Production

Before full production, the manufacturer produces sample bearings for testing.

Samples allow you to check:

• Dimensions
• Noise level
• Smoothness
• Tolerance
• Sealing effectiveness
• Overall performance

It’s important to test samples in your actual equipment when possible.

Step 5: Customer Testing and Approval

Your engineering or maintenance team reviews the samples. If adjustments are needed, the manufacturer revises the design before mass production.

Approval serves as the official go-ahead for the factory.
