Long operating cycles, short maintenance intervals are of extreme economic importance mainly in the cement industry, the mining and drilling industry and in the ship, wind and paper industry. With individual products and solutions from ttv you secure this advantage. The elastic type AX-3M can be mounted in split housings without retaining plate and still reliably seals, even with large offset. At maximum pressure of 0.5 bar and a maximum sliding speed of 20 m/s D5 and D5S are the perfect solutions. Back to back with a circumferential groove in the housing for the supply of lubricant the designs D6 and D7 can be used. Where the shaft cannot be dismantled and fastest restoration is required, ttv offers split rings.
