A seal device has a generally cylindrical body forming a seating for a bearing and encloses that bearing, there being a rectangular front part which bears an orifice of shape in the embodiment of V-shape in transverse cross-section to receive a complementary edge of a member supported by the bearing so that the bearing and member can co-operate while the seal device seals the bearing against entrance of dirt, debris etc., and lubricates it as it is packed with lubricant, there being lubricant-charged felt pads in housings which wipe the member in use.
