    摘要: A pipe inspection system may include a cable storage drum and a length of resilient flexible push-cable. An asymmetric bearing device supports the cable storage drum for rotation about the rotational axis in a pay-out direction and an opposite pay-in direction. In one embodiment, the asymmetric bearing device automatically decreases, without the for manual adjustment, an amount of friction exerted against rotation of the cable storage drum upon reversal of the direction of rotation of the cable storage drum from the pay-out direction to the pay-in direction.
