Energy-saving coupling "Mega Flow Series"

The residual pressure release function lowers the compressor's set pressure, contributing to reduced electricity costs. Easy to connect.

The "Mega Flow Series" is a full-flow design coupling (shaft joint) that simultaneously addresses pressure loss, flow loss, and air leakage. By eliminating resistance inside the coupling and reducing pressure loss, it is possible to lower the set pressure of the compressor, contributing to reduced electricity costs. There are compact and ball valve types available, allowing you to choose the lever shape according to the application, such as at the hand-held part of air tools. 【Features】 - Equipped with a residual pressure release mechanism to prevent whip action of hoses and recoil when removing tools. - Can be connected without pressure as there is no air pressure applied during plug connection. - Includes a locking mechanism to prevent disconnection during use. - Supports one-touch connection. *For more details, please refer to the documentation. Feel free to contact us with any inquiries.

ハースカップリングとカービックカップリングの違い

ハースカップリングとカービックカップリングはどう違う?

「ハースカップリング」の歯形は直線歯形で直線あるいは内側に行くにつれ細くなっていくテーパ形状です。 その為、歯当りが小さく面圧は大きくなる場合もあり、半面歯当りのコントロールなどは難しいです。 「カービックカップリング」の歯形はコンベックス歯(凸歯)とコンケーブ歯(凹歯)が用いられ結合されます。 特徴として、カップリングの中でも締結剛性・割出精度がある事です。「ハースカップリング」よりも高い求心性を持つのが特徴です。 高精度に加工するためには専用機が必要ですが工作機械や、専用機・航空機などは、 より高精度な位置決め精度が必要な為、多くの工作機械メーカーで用いられております。 特に私たちオージックで製造しているカービックカップリングは、 工作機械での実績を多く持っておりお客様から大変好評を得ております。 ハースカップリングからカービックカップリングへの設計変更案件なども対応しておりますので、 ぜひお気軽にお問い合わせください!
