摘要： A hub spindle bearing unit for the wheel is equipped with an inner ring having inner ring raceway surfaces formed on the outer peripheral surface of the shaft section itself of the hub spindle or an inner ring forming annular member formed separately from the shaft section, an outer ring member having outer ring raceway surfaces formed corresponding to the inner ring raceway surfaces, and balls rotatably disposed between the inner and outer rings, a groove section configured as a fragile section in which the strength against the shaft bending direction load exerted to the hub spindle is weaker than the strength of the hub spindle is formed in the outer ring member, and the groove section is deformed and broken earlier than the hub spindle when an excessive shaft bending direction load exceeding a load to be input during ordinary use is input to the hub spindle.

摘要： A hub unit is configured such that nitrogen gas, which functions as inert gas, is filled in a rolling element arranging space which is defined by an inner circumferential surface of an outer ring and an outer circumferential surface of a hub wheel for arranging rolling elements therein in such a manner as to be sealed therein in a semi-hermetically closed state by a seal member and a cover, so as to prevent the nitrogen gas from flowing out to an exterior space. The seal member, which is provided at an end portion of the rolling element arranging space which end lies on a vehicle-outer side, is formed as an elastic seal element, and is fixed to the outer ring at one end whereas being secured to the hub wheel at the other end thereof while being elastically deformed, whereby the seal member has a function to prevent the intrusion of water from the exterior space into the rolling element arranging space. This seal member prevents the inert gas filled in the rolling element arranging space from flowing out to the outside.

摘要： The life of a linear guide device which can be employed in an environment where high cleanness or oil free is required is prolonged by using a solid lubricating agent. In order to attain the object, in a linear guide device comprising a guide rail, and a movable unit consisting of: a movable block which is disposed with straddling the guide rail; and balls (rolling elements) which are enclosed in a ball circulation passage disposed in the movable block, at least ball raceway surfaces of the guide rail and the movable unit are coated with a solid lubricating agent, and the clearance between the guide rail and the movable unit is 0 or positive. Although a solid lubricating agent which is susceptible to be affected by a load is used, therefore, the life of the device can be prolonged as compared with the case where a negative clearance is employed.
