Heat Treatment

A critical stage where rings undergo controlled hardening (austenitizing, quenching, tempering) to achieve an optimal hardness of 60-64 HRC, ensuring wear resistance and dimensional stability.

➔
4
Precision Grinding

Automated grinding lines machine the raceways and faces to sub-micron surface finishes (Ra

➔
5
Assembly & QA

Components are cleaned, assembled with rolling elements and cages in a cleanroom environment, lubricated, and sealed. Every single ARY BEARING undergoes 100% automated noise and vibration testing (Ando-meter testing).

4. Core Technical Advantages of ARY BEARING

Choosing an ARY BEARING means investing in a set of tangible technical advantages that translate into real-world performance benefits.

Superior Material Purity

We use vacuum-arc remelted (VAR) steel for critical applications, which contains minimal non-metallic inclusions. This extends the L10 fatigue life by up to 80% compared to standard bearing steel, as defined by ISO 281.

Advanced Raceways Geometry

Our engineers utilize proprietary software to design the osculation and profile of the raceways. This optimized geometry ensures even stress distribution under load, reducing contact pressure and friction torque, leading to cooler operation and energy savings.

High-Performance Sealing

Our low-friction contact seals (2RS) and non-contact shields (ZZ) are designed to provide excellent protection against contaminants while minimizing rotational drag. This dual benefit is critical in harsh environments like mining and agriculture.

Proprietary Lubrication

We partner with leading lubricant manufacturers to develop greases with specific properties (e.g., wide temperature range, water washout resistance, EP additives) tailored for the ARY BEARING and its intended application, ensuring optimal performance from day one.

6. Custom Bearing Solutions: Tailored to Your Exact Needs

Standard bearings don't always fit unique or extreme applications. Our engineering team specializes in developing customized ARY BEARING solutions. We collaborate with you from concept to production to deliver a bearing that meets your precise requirements.

Our Customization Process:

  1. Requirement Analysis: We work with your team to understand the operational parameters: loads (radial, axial, moment), speeds, temperature range, environment (corrosive, vacuum), and desired lifespan.
  2. Design & Simulation: Using advanced FEA (Finite Element Analysis) and CAD software, we design the bearing, simulate its performance under your specific conditions, and optimize for material, internal geometry, and lubrication.
  3. Prototyping & Testing: We manufacture prototypes and subject them to rigorous in-house testing that mimics your application's environment to validate the design and performance predictions.
  4. Serial Production & Support: Once the design is approved, we move to full-scale production under our strict ISO 9001 quality system, followed by ongoing application support.

7. Application Case Study: Slashing Downtime in a Steel Mill

Challenge:

A major steel rolling mill was experiencing frequent, costly bearing failures in their continuous casting line rollers. The combination of extreme heat (~200°C), heavy shock loads, and water contamination was causing standard bearings to fail in as little as three months, leading to significant unplanned downtime and production losses.

Solution:

Our engineers conducted an on-site analysis and proposed a custom ARY BEARING solution: a specially designed spherical roller bearing featuring:

  • Material: A heat-stabilized chrome steel (S2 designation) to prevent dimensional changes at high temperatures.
  • Clearance: A C4 internal clearance to accommodate thermal expansion of the shaft and housing.
  • Sealing: A high-performance triple-lip contact seal to effectively block out water and scale.
  • Lubrication: A high-temperature, water-resistant polyurea-based grease.

Result:

After implementing the custom ARY BEARING solution, the average bearing lifespan increased from 3 months to over 18 months—a 500% improvement. This resulted in a 30% reduction in annual maintenance downtime for the casting line and an estimated annual savings of over $250,000 in replacement parts and lost production. This case study demonstrates the tangible ROI of investing in a high-quality, application-specific bearing solution.

8. Frequently Asked Questions (FAQ) about ARY BEARING

We've compiled answers to some of the most common technical questions to enhance your understanding and confidence in ARY BEARING products.

1. What is the difference between GCr15 and 440C stainless steel for an ARY BEARING?

GCr15 (AISI 52100) is the industry-standard high-carbon chromium bearing steel. It offers excellent hardness, wear resistance, and high load-carrying capacity. However, it has poor corrosion resistance. 440C Stainless Steel provides excellent corrosion resistance, making it ideal for food processing, medical, and chemical applications. Its load capacity is approximately 20% lower than GCr15, and it is generally more expensive. The choice depends on the operating environment.

2. How do I interpret bearing clearance codes like 'C3'?

Bearing internal clearance is the total distance one ring can move relative to the other. 'CN' (Normal) is standard. C3 clearance means the internal clearance is greater than normal. This is required in applications where there's a significant temperature difference between the inner and outer rings (e.g., electric motors), or where a tight press-fit is used. The extra space prevents the bearing from seizing due to thermal expansion.

3. What is L10 bearing life and how is it calculated?

L10 life, as defined by ISO 281, is a statistical measure of bearing life. It's the number of revolutions (or hours at a given speed) that 90% of a group of identical bearings will complete or exceed before the first evidence of fatigue failure develops. The basic formula is L10 = (C/P)^p, where C is the dynamic load rating, P is the equivalent dynamic load, and 'p' is an exponent (3 for ball bearings, 10/3 for roller bearings). Our engineers can help you perform precise life calculations for your specific application.

4. What are the primary signs of a failing ARY BEARING?

Early warning signs include an increase in operating temperature, a noticeable change in noise (e.g., squealing, rumbling, or clicking), and increased vibration levels. Regular monitoring with vibration analysis equipment is the most effective way to detect incipient faults. Visual signs like grease leakage with metallic particles or corrosion are also clear indicators of a problem.

5. What are the advantages of a machined brass cage over a stamped steel cage?

A stamped steel cage (suffix 'J' or no suffix) is lightweight and cost-effective, suitable for many general applications. A machined brass cage (suffix 'M' or 'MA') is a one-piece, more robust design. It offers superior strength, is less prone to resonance and vibration at high speeds, and has better lubricant-guiding properties. It is the preferred choice for large bearings, high-speed applications, and equipment subjected to high levels of vibration and shock loads.

6. What is the standard delivery time and warranty for an ARY BEARING?

For standard stock items, we typically offer a delivery cycle of 3-5 business days within domestic markets and 7-14 days internationally. For custom solutions, the lead time is project-dependent and will be communicated during the quotation phase. All ARY BEARING products come with a comprehensive 18-month warranty against manufacturing defects, demonstrating our commitment to quality and trustworthiness.

7. How can I get technical support for my application?

We provide extensive customer support. You can reach our team of application engineers via the contact form on our website, email, or phone. We offer assistance with bearing selection, life calculations, mounting procedures, and failure analysis to ensure you get the maximum performance and life from your ARY BEARING.
