Product Description

Introduce

Our company is a professional manufacturer of linear optical axes. The optical axis can be cut according to the customer's own usage. Our size rules are quite complete. The following prices are ex factory prices per meter (EWX). If you need to decide on different lengths, please contact us. When customers choose a linear optical axis, they usually have requirements for surface hardness. The purpose of external surface hardness is to improve wear resistance. For metal materials, the higher the hardness, the better the wear resistance, but the harder the core, the lower the toughness. The load resistance and impact resistance are reduced, therefore the important shaft requirements are: a hard outer and a hard inner. So, what is the difference between a hard axis and a soft axis? Hard axis: Hard axis refers to a linear optical axis whose surface has undergone high-frequency quenching treatment. Its hardness usually reaches around HRC60 and can be used in conjunction with linear bearings. Flexible shaft: A flexible shaft is a linear optical shaft with an unhardened surface. Usually used for transmission. The flexible shaft has not undergone induction hardening. Its hardness is usually HB200-300, approximately equivalent to HRC25. Flexible shafts are not suitable for linear bearings. Use. If you have any questions about the shaft, please consult our customer service and we will serve you as soon as possible
