Flexible Bolt Coupling



Flexible bolt couplings MUVP GOST 21424-93

muvpFlexible bolt couplings (MUVP) are used to connect the coaxial shafts in the transmission of torque from 6.3 Nm to 16,000 Nm and reduction of dynamic loads.
The rings are made of oil and petrol resistant rubber;
The temperature range from -50 ° C to + 130 ° C.
Flexible couplings are intended for installation in actuators operating with load fluctuations. The simplest of flexible couplings is a flexible bolt coupling (MUVP). Impact at load fluctuations are amortized by elastic rubber sleeves, put on steel fingers.
