Today we will introduce the confirmation of manufacturing process method of NSK UCP205,

Casting parts structure and the casting process analysis, NSK UCP 205 bearing block is used for 

clamping bearing, thereby supporting role on the shaft and the shaft parts. The weight of the casting

is about 10 kg, the materials of parts are for HT200,and the outline size is 215x80x146 mm,and was 

produced for large quantities.Due to that the casting is small,it is better to adopt the USES veil and 

back yarn combination of wet.The entire shape with UCP 205 bearing parting surfaces, and use wood 

as Φ62.5 sand core, and are basically on a flat surface, so choosing the shape as a whole UCP 205 bearing 

parting surface, so that the entire cavity is in the type, also facilitate security riser.


The casting parts are for HT200, volume shrinkage ratio is small, but this casting belongs to the thick entity, 

so should be pay attention to the happening of the shrinkage cavity defects, so the location and direction of 

the SPR is very important, according to the structural characteristics of casting parts, with the principle of 

directional solidification, the ends of the internal spruce should base on one side of the introduction, this can

also prevent bad Φ 62.5 sand mold, the resist pressure side slit gate, which can reduce the contact thermal 

gate and casting section, and can avoid the middle thick part overheating, and can shorten the coagulation time, 

is beneficial to get qualified casting parts, in addition, due to the pressure side gate feeding effect is good, 


so do not need to set up the casting feeding riser, to prevent the air hole, can be set position on the edge of

 the top center slants a Φ 8 -- 10 mm Φ gas riser.
