YDTech® manufacturers of needle pins (SS316,SS304,SS302) and cylindrical rollers ! supplier of needle rollers(SS440C,SS420C,SS304,SS303) in china.

precision cylindrical needle rollers: stainless steel 304

AISI type 304 stainless steel cylindrical needle rollers meet requirements for an unhardened ball with excellent toughness and resistance to corrosion. corrosion resistance may be increased through annealing. stainless type 304 cylindrical needle rollers are capable of resisting corrosion by such agents as oxidizing solutions, most organic chemicals, food stuffs and sterilizing solutions. They are moderately resistant to sulfuric acids. Non-magnetic properties available upon request.

precision cylindrical needle rollers: stainless steel 302

AISI type 302 stainless steel cylindrical needle rollers meet requirements for an unhardened rollers with excellent toughness and resistance to corrosion. corrosion resistance may be increased through annealing. Stainless type 302 cylindrical needle rollers are capable of resisting corrosion by such agents as oxidizing solutions, most organic chemicals, food stuffs and sterilizing solutions. they are moderately resistant to sulfuric acids. Non-magnetic properties available upon request.

precision cylindrical needle rollers: stainless steel 316

AISI type 316 stainless steel cylindrical needle rollers meet requirements for an unhardened rollers with excellent toughness and resistance to corrosion. corrosion resistance may be increased through annealing. type 316 is a low carbon austenitic, chromium-nickel-molybdenum stainless steel with corrosion resistance superior to most other chromium-nickel stainless steels in many types of chemical corrodents, as well as marine atmospheres. applications include, phosphate industry parts, textile finishing equipment, printing equipment, body jewelry and valve industries
