Series 4900

Adjustable accumulation conveyor rollers are used where piece goods up to 100 kg must be transported and stopped. The cost–effective accumulation roller conveyors can be stopped at any time with a single, permanently running drive. An accumulator bush is located between the roller shell and the drive element. The drive element is able to rotate although the roller shell is blocked with the stopped material to be conveyed. Resistant to temperatures from –10°C to +40°C.
