Popular Design for 5.5 Mm Steel Balls - Chrome steel balls high quality precision – Mingzhu Detail:

Chrome steel balls are primarily used in precision ball bearings and in a large variety of industrial applications, like vehicles components, machine tools, valves, bikes and pumps.

Chrome steel balls, which is the result of years of experiments with various analyses for manufacturing of bearings, have a superior surface finishing, an extraordinary hardness, and dimensional precision and a good carrying capacity, along with a great wear and deformation resistance. Thanks to these special mechanic properties, chrome steel balls are widely utilized to produce mechanical components.

As a professional chrome steel balls manufacturer, Haimen City Mingzhu Steel Ball Co., Ltd. is poised to provide high quality and lower cost products to all customers.

FAQ

Q: Do chrome steel balls perform better than carbon steel balls?
A: Chrome steel balls contain more alloy metals, which contribute toughness, hardness, resistant and are able to operate under heavy load, so are widely utilized in bearing and other industrial application. Carbon steel balls are only case-hardened. The interior part doesn’t achieve the same hardness as the surface. The application is drawer sliders, chair casters and toys.

Q: What standards do you adhere to for manufacturing?
A: Our products are in compliance with the following standards industrial for steel balls:
● ISO 3290 (INTERNATIONAL)
● DIN 5401 (GER)
● AISI/ AFBMA (USA)
● JIS B1501 (JAP)
● GB/T308 (CHN)

Q: What kind of certificates do you achieve?
A: We own ISO9001:2008 management system certification and IATF16949: 2016 automotive industry quality management system certification.

Q: How is your quality assurance?
A: All produced balls are 100% sorted by the sorting bar and checked by the photoelectric surface defect detector. Before packaging samples balls from the lot are to send for final inspection to check for the roughness, roundness, hardness, variation, crush load and vibration in compliance with the standard. If all requirements are met, a inspection report will be made for the customer. Our sophisticated laboratory is equipped with high precision machines and equipment: Rockwell hardness tester, Vickers hardness tester, crushing load machine, roughness meter, roundness meter, diameter comparator, metallographic microscope, vibration measuring instrument, etc..

Q: Do you offer free samples for test?
A: Yes, we provide free samples to test and check quality.

Q: How long is your lead time?
A: Generally it takes around 3-5 days if the products are in stock. Or else the estimated lead time should be worked out according to your specific quantity, material and grade.

Q: We are not familiar with the international transportation. Will you handle all logistics?
A: Definitely, we deal with the logistic issues with our cooperated international freight forwarders with years’ of experience. The customers only need to provide us the basic information

Q: How is your packaging method?
A: 1. Conventional packaging method: 4 Inner boxes (14.5cm*9.5cm*8cm) per master carton (30cm*20cm*17cm) with dry plastic bag with VCI anti-rust paper or oiled plastic bag, 24 cartons per wooden pallet (80cm*60cm*65cm). Each carton weighs roughly 23kgs;
2.Steel drum packaging method: 4 steel drums (∅35cm*55cm) with dry plastic bag with VCI anti-rust paper or oiled plastic bag,4 drums per wooden pallet (74cm*74cm*55cm);
3.Customized packaging as per customer’s requirement.
