Import Bearings For Mass-Spring Systems — Buy in wholesale FOB from Supplier in China

These precision ball bearings from Henan Anson Steel Co., Ltd. are engineered specifically for mass-spring systems where vibration control and acoustic performance are critical. Manufactured from high-carbon chrome steel (GCr15), they meet ABEC 7/9 precision standards with noise levels controlled below 20dB. The bearings conform to ISO 15 and DIN specifications, using vacuum-degassed chrome steel to ensure consistent performance under high-speed and high-load conditions. Available in various bore sizes and configurations, they serve semiconductor equipment, medical imaging systems, aerospace actuators, and precision robotics applications.

The GCr15 material provides a typical hardness of 60-64 HRC after heat treatment, with standard chromium content of 1.3-1.65% and carbon content of 0.95-1.05%. Vacuum degassing reduces oxygen content below 15 ppm, improving fatigue life by eliminating non-metallic inclusions. Typical dimensional tolerances for ABEC 7 bearings run to ±0.0025 mm on bore diameter, with radial runout of 2.5 microns. ABEC 9 variants achieve ±0.0012 mm bore tolerance and 1.5 micron runout. Standard cage materials include phenolic resin or brass, selected for rotational speed and temperature requirements. Lubrication grooves and holes can be specified per application.

Buyers include OEMs in semiconductor wafer handling, MRI and CT scanner manufacturers, satellite actuator suppliers, and precision robot arm integrators. The bearings suit any system requiring sub-micron positioning accuracy with minimal transmitted vibration. Packaging is typically individual vacuum-sealed with desiccant, then boxed in anti-static foam. Lead time, MOQ, and exact price band should be confirmed directly with Henan Anson Steel Co., Ltd. given their current response rate data. FOB or CIF terms from Chinese ports are standard for this category.

Henan Anson Steel Co., Ltd. is based in Anyang, Henan Province, China, with its registered address at Room 305, Kechuang Mansion. The company holds a harbor trust tier on the marketplace, indicating a baseline verification level. Its response rate is currently recorded at 0.00% with zero average response hours, which means prospective buyers should anticipate delays in initial communication and may need to follow up persistently or use alternative contact methods to engage with the supplier.

The supplier's listing focuses on precision bearings for mass-spring systems, positioning itself toward industrial OEM procurement rather than commodity aftermarket sales. No verified factory size, annual revenue, specific year of establishment, or named client references appear in the available profile data. Buyers should independently verify production capacity, quality system certifications such as ISO 9001 or IATF 16949, and whether the company manufactures in-house or sources from sub-suppliers. The GCr15 material specification and ABEC 7/9 claims should be confirmed via mill certificates and third-party inspection reports before committing to volume orders.
