Jolly Bushings

The Jolly Bushing are oversized bushings designed and produced to allow for quick and easy replacement of the bushing in its seat.

In particular, this bushing has an inner surface which has been hardened to 58-62 HRC and ground, plus a soft 40-42 HRC external surface (including the two faces), which can be machined (turned) to the required diameter. The thickness of this special bushing is greater (>7.5 mm) than a standard bushing so that it can be better adapted to the type of housing (which has lost its initial dimension due to wear). So, instead of replacing the housing and the bushing, we only replace the latter with a JBTM turned to the external diameter, so the best interference fit between the housing and bushing can be obtained, saving time and money.
