20100092117 | Wheel Bearing Apparatus Incorporated With A Wheel Speed Detecting Apparatus - A wheel bearing apparatus incorporating a wheel speed detecting apparatus has an outer member, an inner member, double row rolling elements, a sensor holder, and a pulser ring. The sensor holder cover has a cylindrical fitting portion press-fit onto the inner side end portion of the outer member. A flange portion extends radially inward from the fitting portion. The flange portion is in close contact with the end face of the outer member. A bottom portion extends further radially inward from the flange portion. The holding portion is integrally joined to the bottom portion. The flange portion is formed with a flat surface so that it forms an abutting width larger than 5 mm or more, against the end face of the outer member, or larger than 50% or more, relative to the flat width of the end face of the outer member. | 04-15-2010 |
20130051720 | Wheel Bearing Apparatus - A wheel bearing apparatus has an outer member, an inner member, and double row rolling elements are contained between the outer raceway surfaces. Seals are mounted in openings formed between the outer member and the inner member. A shoulder height H of the inner raceway surface of the inner ring is set with a range of 0.4-0.8 times a diameter “d” of the ball (H/d=0.4-0.8). A shoulder height δ of a smaller diameter portion formed on the outermost circumference of the inner ring is set to a value δ/d≧0.35. A corner, formed by the tapered surface and the inner raceway surface, is rounded to have a circular arc cross-section. A shoulder height H | 02-28-2013 |
20130157915 | GREASE COMPOSITION FOR HUB UNIT BEARING - The invention provides a grease composition for huh unit bearing, containing (a) an aromatic diurea thickener, (b) a base oil, (c) a metal salt of oxidized wax, (d) diphenyl hydrogen phosphate, and (e) at least one rust preventive selected from the group consisting of sulfonate rust preventives and carboxylic acid rust preventives. The grease composition of the invention shows excellent anti-fretting properties at low temperature, and at the same time, exhibit excellent rust preventing properties. | 06-20-2013 |
20140346850 | Wheel Bearing Apparatus For A Vehicle - A vehicle wheel bearing apparatus has an outer member, an inner member, double row rolling elements, and seals. At least one seal of the seals has a metal core press-formed from steel sheet with a cylindrical fitting portion. A radial portion extends radially inward from the end of the fitting portion. A sealing member with a plurality of sealing lips is integrally adhered to the fitting portion of the metal core. Bearing grease is contained within the bearing. Sealing grease is applied to the sealing lips. Both the bearing grease and the sealing grease use the same thickener and the worked penetration of 350 or less. The kinematic viscosity of the base oil of the sealing grease at 40° C. is set to 70% or less of the kinematic viscosity of the base oil of the bearing grease at 40° C. | 11-27-2014 |
