1. Solid Bar Material for Enhanced Structure
Overcoming the inherent uneven wall thickness inherent in tube processing, AISI420 solid round steel is used as the raw material. Precision machining results in higher metal density in both inner and outer rings, improving impact and deformation resistance by 30%, making it suitable for high-frequency start-stop and vibration conditions.
2. One-Stop In-House Production with Full Precision Control
From steel procurement, machining, heat treatment, grinding to assembly, the entire process is completed in-house, eliminating outsourcing. Strict adherence to ISO 9001 standards ensures dimensional tolerances are controlled within ±0.002mm, guaranteeing consistent performance across every batch.
3. AISI420 Main Material: Excellent Wear and Corrosion Resistance
The main material is AISI420 martensitic stainless steel (AISI440/304/316 can be customized). After quenching and tempering, the hardness reaches HRC 58-62, combining excellent wear resistance and basic corrosion resistance, suitable for common corrosive environments such as fresh water, weak acids, and atmospheric corrosion. 304/316 materials are also available to meet the needs of high salt spray and strong corrosion scenarios.
4. G10 Grade Steel Balls: Quieter and More Efficient Operation
Standard configuration includes G10 grade high-precision stainless steel balls with a roundness error ≤0.0005mm and a surface roughness Ra≤0.01μm. This results in low rolling resistance and operating noise as low as 28dB, suitable for equipment with high noise requirements such as motors and precision instruments.
5. Customized Seals and Greases for All Operating Conditions
Sealing Rings: ZZ metal dust caps (dustproof and splashproof), 2RS nitrile rubber (oil and wear resistant, -40℃~120℃), fluororubber (acid and alkali resistant, high temperature resistant, -20℃~250℃) are available.
Greases: Standard lithium-based grease, food-grade white oil (FDA certified), high-temperature grease, low-temperature grease, etc., can be precisely matched according to customer operating conditions to meet hygiene requirements in food processing, medical equipment, etc.
6. Multi-Material Retainers for Diverse Needs
Retainers are available in 430/201/304 stainless steel, possessing excellent temperature resistance and corrosion resistance, perfectly matching the bearing inner ring and steel balls, avoiding frictional heat and material aging during high-speed operation.
