Bearing for baitreel and spool. Ceramic bearing sounds, low sound type; Type S is recommended for oil use. (Recommended oil, our original No. 4 or similar viscosity to stainless bearings and low viscosity oil or oilless) We recommend the bearing HXR, HX (oil in can be used as a specification) We have developed this product for customers who wish to reduce bearing noise. However, ceramic bearings are made of a material that is prone to bearing sounds, so stainless steel bearings do not have the same (noise) oil in, oil less for distance and performance changes. Based on HXR bearings, we have revised the sound of the bearing from the materials and so on, and the sound of the bearing has been improved and noised. Oil viscosity is very important and low viscosity oil, oilless, the more you get distance, the better performance, but the bearing sound will appear. Depending on the maker, structure, and material of the bearing sounds, distance, etc. The outer and inner diameter parts are made of stainless steel material. The ball is made of silicon nitride material (ceramic), which is excellent in heat, strength, shock, and smoothness, and has a high precision ball. ● Shipping method will be a click post. ●Please refrain from any questions regarding the price discount. ●Please be aware that the day and time of delivery cannot be specified.
