Claims

[Scope of utility model registration request]

A bearing body having a large number of rolling elements, a bearing body having a linear rolling groove formed on at least one side, and a notch for mounting the bearing body, the rolling element being guided on the circumferential surface of the notch, and In a circulating linear motion bearing comprising a pair of cages formed with rolling grooves for circulating the bearing, a seal lip having the same shape as the cross section of the rolling groove of the track rail on which the circulating linear motion bearing runs; , a seal member integrally formed with a bottom portion having an elastic pressure piece for pressing the seal lip against the rolling groove of the track rail with a predetermined pressure, and a fitting portion having a narrower portion than the bottom portion; A circulation type linear motion bearing, characterized in that it is installed at both ends of the cage.
