RL系列膜片聯軸器是結合歐洲與日本等優質產品基礎之上獨立開發的高品質產品。膜片式聯軸器擁有更小的體積，更大的同型扭矩和更合理的配比尺寸，補償范圍大，質量輕轉動慣量小螺栓與膜片組的孔連接部位采用特殊的彈性墊套設計，極大減小了孔緣部位應力的集中，杜絕膜片的撕裂交損，延長使用壽命。

膜片彈性聯軸器采用模塊化設計，裝配簡單，維修更換快捷。性能遠超國標JM系列產品，大量應用于風機系統，汽輪機組及其他重要工業領域。

彈性膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。彈性聯軸器結構緊湊，傳遞扭矩大，使用壽命長，免維護，耐高溫，耐酸堿防腐蝕，適用于高溫高速及有腐蝕工況環境的軸系傳動。

The steel lamina coupling is an efficient flexible coupling with no back clearance and free from maintenance. Due to its unique structural design, it can achieve the perfect delivery of torque. Meanwhile, it has excellent performances, including large axial and radial compensation ability, low reply feedback force and wide thermal adaptability, etc. With different change design, it can be applied at most power transmission sites.

Rokee's RL series steel laminae coupling is a high-quality product developed independently on basis of combination of advanced products from Europe and Japan, etc. It has smaller size, larger torque of the same model, more reasonable proportioning size, large compensation scope, light weight and small rotational inertia. With modularized design, it’s easy for assembly, maintenance and replacement. Its performance far exceeds the one of JM series diaphragm coupling. It’s widely applied in the fields of fan systems, turboset and other pumps, etc.

膜片脹套聯軸器是通用機械設備電機與軸承或兩軸相連接的中間件，聯軸器具備高扭矩剛性、零回轉間隙、彈性體補償制造機械在傳動過程中兩軸所產生的徑向、軸向、角向偏差、順時針與逆時針回轉特性相平等特點。為造紙、冶金、紡織、造船、農機、運輸、化工、輕工等行業設備作出重大貢獻。

梅花脹套聯軸器通過擰緊聯軸器端面的四顆定位螺絲壓迫脹套方式脹緊固定，適用于一些扭力大的步進電機和伺服電機的聯結固定。梅花脹套聯軸器常用于伺服電機，步進電機，數控機床，數控車床，加工中心，雕刻機，走心機，龍門加工中心，臥式加工中心等通用機械設備。
