珩(heng)(heng)(heng)磨(mo)管采用滾壓(ya)加工，由于(yu)表面(mian)層留有(you)表面(mian)殘(can)余壓(ya)應力，可(ke)以幫(bang)助于(yu)表面(mian)微小(xiao)裂(lie)紋的(de)封閉，阻止侵蝕作(zuo)用的(de)擴展。從(cong)而增(zeng)加表面(mian)抗腐蝕能力，并能減(jian)(jian)小(xiao)疲勞裂(lie)紋的(de)產生或擴大，因而增(zeng)加珩(heng)(heng)(heng)磨(mo)管疲勞強(qiang)(qiang)度。通過(guo)滾壓(ya)成型，滾壓(ya)表面(mian)形成一(yi)層冷作(zuo)硬化層，減(jian)(jian)少(shao)了磨(mo)削副(fu)接(jie)觸(chu)表面(mian)的(de)性和(he)塑性變形，滾壓(ya)后(hou)，表面(mian)粗(cu)糙度值(zhi)的(de)減(jian)(jian)小(xiao)，可(ke)增(zeng)加配(pei)合性質缸(gang)(gang)筒(tong)是液(ye)壓(ya)缸(gang)(gang)的(de)主體，其內孔(kong)一(yi)般采用鏜(tang)削、鉸孔(kong)、滾壓(ya)或珩(heng)(heng)(heng)磨(mo)管等(deng)精密(mi)(mi)加工工藝制造（又(you)稱(cheng)冷拔管，珩(heng)(heng)(heng)磨(mo)管），使活(huo)塞(sai)及其密(mi)(mi)封件(jian)、支承件(jian)能順利滑動，從(cong)而保證密(mi)(mi)封效(xiao)果(guo)，減(jian)(jian)少(shao)磨(mo)損；液(ye)壓(ya)油缸(gang)(gang)缸(gang)(gang)筒(tong)要(yao)承受(shou)很大的(de)液(ye)壓(ya)力，因此(ci)，應有(you)足夠的(de)強(qiang)(qiang)度和(he)剛(gang)度。 端蓋在缸(gang)(gang)筒(tong)的(de)兩端，與缸(gang)(gang)筒(tong)形成密(mi)(mi)閉油腔，因此(ci)，端蓋及其連接(jie)件(jian)都應有(you)足夠的(de)強(qiang)(qiang)度。設計時既要(yao)考慮強(qiang)(qiang)度，又(you)要(yao)選擇(ze)工藝性較(jiao)好的(de)結構形式。導向(xiang)套(tao)對活(huo)塞(sai)或柱塞(sai)起(qi)導向(xiang)和(he)支承作(zuo)用，有(you)些液(ye)壓(ya)缸(gang)(gang)不設導向(xiang)套(tao)，直接(jie)用端蓋孔(kong)導向(xiang)，這(zhe)種(zhong)結構簡(jian)單，但磨(mo)損后(hou)必須更換(huan)端蓋
