轴承钢棒 - 精密轴承用高碳铬钢

轴承钢棒代表了一类专门为制造滚动轴承和精密机械部件而设计的高碳铬合金钢。这种优质材料广泛应用于汽车变速器、工业机械、航空航天系统以及高速旋转设备中,在这些应用中,卓越的硬度、耐磨性和循环载荷下的尺寸稳定性至关重要。轴承钢棒按照包括 AISI 52100、DIN 100Cr6 和 JIS SUJ2 在内的严格冶金标准制造,在要求疲劳抗力超过 10^9 应力循环的应用中发挥着关键作用。

轴承钢棒供应商

什么是轴承钢棒?

轴承钢棒是一种淬透性合金钢,含有约 0.95-1.10% 的碳和 1.30-1.60% 的铬,经热处理后可达到 58-65 HRC 的表面硬度。该材料具有优异的抗滚动接触疲劳性能,在高达 150°C 的工作温度下保持显微组织稳定性,并展现出卓越的尺寸精度,直径公差可达到 ISO h6 级。

轴承钢棒技术规格

根据 ASTM A295 的典型化学成分包括碳 0.98-1.10%、铬 1.30-1.60%、锰 0.25-0.45%、硅 0.15-0.35%,磷和硫各自限制在最高 0.025%。材料以退火状态供应,硬度不超过 241 HBW,具有细珠光体基体与均匀分布球化碳化物的显微组织。标准制造尺寸范围为直径 10mm 至 150mm,采用热轧或冷拔表面,长度可达 6 米,符合 EN 10084:2008 尺寸要求。

为什么选择我们的轴承钢棒

我们的轴承钢棒材通过真空脱气和连铸工艺生产,确保氧含量低于10 ppm,非金属夹杂物评级符合ASTM E45 Method A的A级要求。每个生产批次均按照SEP 1921 Class 3标准进行超声波检测,确保关键轴承应用的材料完整性。我们维护ISO 9001:2015认证的质量体系,具备从钢厂到交付的全程可追溯性,提供记录化学成分分析、力学性能和热处理记录的材料测试证书。

常见问题

最小起订量(MOQ)是多少?

我们的标准MOQ为每种规格5公吨,但对于特殊直径或定制化学成分,我们可接受1-2吨的较小数量,并相应调整交货时间。满足5吨门槛的混合尺寸订单可享受标准钢厂直销价格。

轴承钢棒材制造商

你们提供材料测试证书吗?

是的,我们每批货物均提供EN 10204 Type 3.1证书,记录炉次分析的化学成分、拉伸性能、硬度值和晶粒度测量结果。在报价阶段可根据要求提供额外认证,包括超声波检测报告和脱碳层深度分析。

典型交货时间是多少?

标准直径轴承钢棒材(20-80mm)退火状态,库存规格自订单确认起25-35天内发货。定制尺寸或特殊热处理条件需要45-60天制造周期,具体取决于钢厂生产计划和订购数量。

你们能按定制尺寸切割吗?

我们提供精密切割服务,长度在500mm至6000mm之间,公差可达±1mm。冷锯切割可保持材料性能,不会引入热应力,切割端面可按图纸规格进行端面加工和倒角。切割费用根据数量和复杂程度收取,详情见报价单。

Perfect 52100 Steel Bar for High-Precision Bearing Assembly
We ordered 10 tons of AISI 52100 bearing steel bar in 20mm, 30mm, and 40mm diameters for our precision bearing manufacturing facility in Ohio. Material arrived in 26 days with comprehensive documentation including chemical analysis showing carbon at 1.01%, chromium at 1.48%, and sulfur at 0.018%. Ultrasonic testing confirmed zero internal defects per SEP 1921 standards. Annealed hardness measured consistently at 235-240 HBW. After our proprietary heat treatment, material achieved 63 HRC with excellent dimensional stability. Compared quotes from 4 domestic suppliers - this offered best combination of quality certification and competitive pricing. Already planning repeat order for Q2 production requirements.

Acceptable Quality with Initial Documentation Delay
Ordered 7 tons of bearing steel bar in 80mm diameter for agricultural machinery bearing production. Material quality met ASTM A295 specifications after verification testing in our laboratory. Initial shipment arrived without complete EN 10204 3.1 certificates - documentation was provided 5 days later after our request. Chemical composition and mechanical properties were within specification range. Dimensional accuracy was acceptable at h10 tolerance grade. Supplier resolved certificate issue professionally and offered discount on next order. Material performed adequately in production. Would order again with clear documentation requirements specified upfront.

Reliable 52100 Steel for Construction Equipment Bearings
Purchased 4 tons of 52100 bearing steel bar in 70mm diameter for heavy construction equipment bearing repairs. Material certificates confirmed carbon content at 1.04% and proper chromium levels. Hardness uniformity was good at 238-241 HBW across different bars. Surface finish had minor handling marks on 2 bars but did not affect machining operations. Delivery to Dubai took 35 days, within acceptable range. Price point was reasonable for Middle East market. Supplier accommodated our request for additional ultrasonic testing documentation at no extra charge. Would recommend for industrial applications where slight cosmetic imperfections are tolerable.

Premium Quality Bearing Steel for Marine Winch Systems
Ordered 6.5 tons of bearing steel bar in mixed sizes (30mm, 45mm, 55mm) for marine winch bearing replacement project. Vacuum degassing process evident in material cleanliness with minimal inclusions observed during ultrasonic inspection. Microstructure showed uniform spheroidized carbides ideal for cold forming operations. ISO 9001:2015 certification and full traceability documentation provided confidence for our Lloyd's Register approval process. Delivered to Perth in 30 days including sea freight. Third consecutive order - reliability and consistency make them our preferred supplier for critical marine applications.

Superior 52100 Bar with Custom Cutting Service
Purchased 5 tons of AISI 52100 bearing steel in 60mm diameter with custom cutting to 1200mm lengths for our CNC machining centers. Cold-saw cutting service maintained material integrity with cut tolerances within ±0.5mm. Supplied with both heat analysis and mechanical property certificates documenting tensile strength at 685 MPa. Decarburization depth was less than 0.15mm, excellent for our grinding operations. Sales team responded within 4 hours with detailed quotation including freight costs to Manchester. Material performed flawlessly in production trials achieving 1.2 billion stress cycles in fatigue testing.

Good Value 100Cr6 Steel for Industrial Bearing Manufacturing
Ordered 12 tons of DIN 100Cr6 bearing steel bar in 50mm diameter for industrial gearbox bearings. Material quality was solid with hardness at 235 HBW in annealed condition, meeting EN 10084:2008 requirements. Dimensional tolerances were within ISO h9 grade, slightly looser than our preferred h8 but acceptable for our machining process. Price was competitive compared to European mills. Delivery took 32 days, slightly longer than quoted 25-30 days but still reasonable. Would order again for non-critical applications where cost is a priority.

Outstanding Quality SUJ2 Material for Aerospace Bearings
We purchased 3 tons of bearing steel bar in 25mm and 35mm diameters for aerospace bearing components. Material test certificates showed oxygen content at 8 ppm, well below the 10 ppm specification. Grain size measured at ASTM 10-11, ideal for our precision machining requirements. Non-metallic inclusion rating was Grade A per ASTM E45, critical for our fatigue-critical applications. Technical support team provided detailed heat treatment recommendations. Packaging was excellent with individual bars separated to prevent surface damage during transit.
