Rotary Shafts Straight

Rotary shaft is a high precision shaft product, which can be used in combination with bearing, roller, pulley or other bushing products. In addition to excellent dimensional and geometric tolerances, it offers a variety of alterations.

Type	D Tolerance	Material	Surface Treatment	D (mm)	L (mm)
E-SFHR	h8 (Grinding Rod)	General structural steel or carbon steel	Ferroferric Oxide Protective Film	2~50	15~1000
E-PSFHR			Electroless Nickel Plating
E-SSFHR		Austenitic stainless steel	-
E-SFR	g7 (Grinding Rod)	General structural steel or carbon steel	Ferroferric Oxide Protective Film
E-PSFR			Electroless Nickel Plating
E-SSFR		Austenitic stainless steel	-

If there are requirements for rust prevention, give priority to the products with surface treatment of electroless nickel plating and products made of austenitic stainless steel. For surface treatment and anti-rust method, please click Anti-Rust Method.
