Custom Stainless Steel Insert Bearings

Custom Stainless Steel Insert Bearings

Shanghai Yinin Bearing & Transmission Company is a Custom Stainless Steel Insert Bearings manufacturer and supplier based in China. With over 20 years of experience in the bearing industry, we design and produce insert bearings that meet the demands of agricultural machinery, food processing equipment, conveyor systems, and industrial gearboxes.

Our range includes SA, SB, UC200, UC300, UCX, NA, UK200, SER, and CS series, each engineered for specific mounting and load requirements. We support both standard and non-standard configurations, with materials selected for corrosion resistance and long service life.

Our Product Range

Application Fit and Material Selection

Insert bearings are designed to mount directly into a housing, compensating for misalignment. Our stainless steel variants are ideal for washdown environments, where moisture and chemicals would degrade standard chrome steel. We offer AISI 440C or 304/316 stainless steel for rings and balls, with seals chosen for temperature and contamination resistance.

For high-speed or high-load applications, we can adjust internal clearance, cage type, and lubrication. Our engineering team reviews the operating conditions—speed, load, temperature, and contamination—to recommend the correct series and material.

Critical Specifications and Performance

• Bore sizes: From 12 mm to 100 mm, depending on series.
• Outer ring tolerance: Spherical OD with tolerance class P0 or P6 as required.
• Static load ratings: Up to 30 kN for larger UCX series.
• Speed limits: Up to 5,000 RPM with proper lubrication.
• Sealing: Double rubber seals (2RS) or metal shields (ZZ) available.

Configuration Options and Customization

We understand that standard catalogs don't always fit. As a Custom Stainless Steel Insert Bearings supplier, we offer:

• Non-standard bore sizes, widths, and outer diameters.
• Special locking mechanisms: set screw, eccentric collar, or adapter sleeve.
• Custom seals and shields for extreme environments.
• Alternative materials, such as duplex stainless steel or ceramic balls.
• Marking, packaging, and anti-corrosion treatments per export requirements.

Quality Assurance and Testing

Our factory in Jiangsu Province operates under ISO9001 quality management. We perform in-process inspections at each manufacturing stage, and finished bearings undergo dimensional checks, radial clearance measurement, noise testing, and visual inspection. For stainless steel products, we verify material composition and corrosion resistance.

We can provide material certificates, inspection reports, and test data upon request. For high-volume orders, we offer statistical process control documentation.

Information We Use to Configure Your Solution

To prepare a precise quotation and technical proposal, we need the following details:

• Bearing series and dimensions (or reference number).
• Operating load (radial/axial) and speed.
• Ambient temperature, humidity, and exposure to chemicals.
• Mounting arrangement (shaft tolerance, housing type).
• Required certifications or industry standards.
• Annual quantity and target delivery schedule.

Send us a drawing or sample for non-standard designs; our technical team will confirm feasibility and lead time.

Installation, Maintenance, and Support

We provide mounting instructions for each series, including recommended shaft tolerances and locking torque. Our after-sales team can assist with troubleshooting and replacement schedules. We stock spare parts for common series and offer rapid dispatch for in-stock items.

Frequently Asked Questions

What is the minimum order quantity for custom insert bearings?

Our MOQ is 100 sets for standard sizes. For fully custom designs, we evaluate tooling and setup costs; a sample order may be required before mass production.

Can you match a specific brand's part number?

Yes, we can produce interchangeable bearings that match dimensions and performance of major brands. Provide the reference number or sample, and we will verify compatibility.

What stainless steel grades do you use?

We commonly use AISI 440C for rings and balls, offering high hardness and corrosion resistance. For more aggressive environments, we can use 316 stainless steel or other alloys.

How do you ensure quality for stainless steel bearings?

We conduct material composition analysis, heat treatment verification, and final dimensional and noise tests. Each batch is traceable, and we provide inspection certificates on request.

What is the typical lead time for custom orders?

Standard products ship within 3 working days if in stock. Custom orders typically take 15-30 days depending on complexity and quantity. We confirm exact lead time after receiving your specifications.
