Peripheral speed

With optimum operating conditions the universal shaft seal ring T51 can be used for peripheral speeds of max. 25 m/s. As for type T61, the allowed peripheral speed depends on the pressure load (Please see diagram).

Hardness of seal surface

Depending on the operating conditions 40 – 45 HRC.

Quality of seal surface

Grinding of the shaft surface must be plunge grinded.

Pressure

The universal shaft seals T51 and T53 are only used in applications without pressure load. With pressure differences, type T52 can be used according to DIN 3769 depending on the rotating speed and peripheral speed (max. 0.5 bar).
