摘要： A seal lip having: a cylindrical seal surface in close contact with an outer peripheral surface of an inner race with outer side and inner side surfaces standing upright respectively from an outer end and an inner end of the seal surface and reaching a lip supporting portion of a seal member, and protruding on an inner peripheral surface of the lip supporting portion. The outer side surface is a perpendicular surface standing upright from the outer end of the seal surface in a direction perpendicular to a generating line of the outer peripheral surface of the inner race. The inner side surface includes: a perpendicular surface standing upright from the inner end of the seal surface in parallel with the outer side surface; and a conical surface inclined toward the outer side surface extending outward in a radial direction from an outer peripheral end of the perpendicular surface.

摘要： A ball bearing with seals on both sides is provided which is configured such that the pressure in the bearing interior is less likely to drop when a belt guide ring cools after it has been formed by resin molding, thus preventing the inwardly extending lip of each rubber seal from being pressed against the inner side surface of the seal groove. The belt guide ring (21) is formed on the radially outer surface of an outer race (2) of the bearing. Seal fitting grooves (8) are formed on the radially inner surface of the outer race (2) at its respective end portions. A rubber seal (10) has its radially outer portion fitted in each seal fitting groove (8). The rubber seal (10) has an inwardly extending lip (12) formed at its radially inner portion and having its tip elastically kept in contact with an inner side surface of one of two seal grooves (9) formed on the radially inner surface of an inner race (3) of the bearing, thereby sealing the bearing interior, and having an inwardly extending lip (12) having a tip which is kept in elastic contact with an inner side surface (9a) of the corresponding seal groove (9), thereby sealing the bearing interior. The contact surface of the inwardly extending seal lip (12) which is in elastic contact with the inner side surface (9a) of the seal groove (9) is formed with a recess (18) extending a limited circumferential range of the contact surface and defining a minute gap in cooperation with the inner side surface (9a) of the seal groove (9). With this arrangement, when the temperature and thus the pressure in the bearing interior rises when the belt guide ring (21) is formed by resin molding, the pressure is released to the exterior of the bearing through the gap defined by the recess (18). The pressure in the bearing interior is thus kept constant when the guide ring cools down after resin molding. This prevents the inwardly extending lip (12) from being pressed hard against the inner side surface (9a) of the seal groove (9) of the inner race (3).

摘要： The invention provides a wheel design that incorporates both a shield and seal on both sides of the guide wheel to eliminate direct liquid pressure on the seal. By retaining the lubrication, bearing life is extended, dramatically reducing machine downtime. In the presently preferred embodiment, the combination of a guide wheel with two rubber spring return (RSR) seals in-bound of two shields, increases guide wheel life through the following: The shields prevent the direct force of a high pressure wash-down from reaching the seal directly. There is a non-direct path between the shield and the outer raceway of the guide wheel to allow any trapped liquid to seep back out of the guide wheel. Also, as the guide wheel rotates, any liquid between the shield and seal is spun-out by centrifugal force.

摘要： In a contact type seal arrangement for a rolling bearing, it is aimed to reduce torque and improve sealability by improving the lip structure of each seal member.Each seal member 11 has a branch portion 15 at substantially the same height as the land 3 of the inner ring. A main lip 16 is defined by its portion extending radially inwardly from the branch portion 15. The tip of the main lip 16 is brought into contact with the outer groove wall 21 of the seal groove 4 to define a contact seal 25. An auxiliary lip 17 is defined by a portion extending axially inwardly from the branch portion 15. A labyrinth seal 19 is defined between the tip of the auxiliary lip 17 and the inner groove wall 18 of the seal groove 4.
