Patent number: 10738825Abstract: A tapered roller bearing assembly includes a one-piece inner ring that has two outer raceways oriented at angles relative to a longitudinal axis and a first outer ring with a first inner raceway and a second outer ring having a second inner raceway. The bearing assembly includes a spacer ring that has an axial width and is positioned around the inner ring and between the first and outer rings. A plurality of rolling elements is in rolling engagement with the first outer raceway and the first inner raceway. A plurality of rolling elements is in rolling engagement with the second outer raceway and the second inner raceway. The axial width is selectively established to obtain a predetermined axial clearance between the inner ring and the first outer ring and the second outer ring.Type: GrantFiled: May 6, 2019Date of Patent: August 11, 2020Assignee: Roller Bearing Company of America, Inc.Inventors: James Prescavage, Roman Malychok

Patent number: 10697493Abstract: A roller assembly includes two outer rings rotatably mounted on a shaft by a respective set of rollers positioned between the shaft and each of the respective one of the outer rings. The shaft has a head flange on one end thereof and a groove formed therein at a distance from the head flange. A retainer ring is positioned in the groove and another retainer ring is secured to the shaft at a distance from the groove. The retaining ring is configured to space the two outer rings apart from one another so that the two outer rings are operable and rotatable independent from one another.Type: GrantFiled: February 14, 2019Date of Patent: June 30, 2020Assignee: Roller Bearing Company of America, Inc.Inventors: Roman Malychok, Lyudmyla Malychok

Patent number: 10458468Abstract: A roller assembly includes an outer ring having an interior area defined by an inner surface extending between a first and second axial end thereof. The inner surface has a bearing surface. A flanged headed shaft having an exterior bearing surface extends into the interior area. The shaft has a circumferential retainer receiving surface thereon. Two rows of rollers are positioned in the interior area with a spacer ring therebetween. A retainer ring is secured to the retainer receiving surface. The two rows of rollers and the spacer are axially retained on the shaft by and between the flanged head and the retaining ring so that the roller assembly withstands an axial load of up to 100 percent of an applied radial load.Type: GrantFiled: January 16, 2019Date of Patent: October 29, 2019Assignee: Roller Bearing Company of America, Inc.Inventors: Roman Malychok, Lyudmyla Malychok

Patent number: 10167896Abstract: A yoke roller assembly includes an inner ring disposed in an outer ring. The yoke roller assembly includes first, second and third rows of rollers positioned between the inner ring and the outer ring. The outer ring has a first width, a first outside diameter and a radially outwardly extending lobe circumferentially extending therearound and formed integrally therewith. The lobe has opposing axial end faces extending a second width, and has a second outside diameter. The second row of rollers are positioned axially inward of the axial end faces of the lobe. The first and third row of rollers each have an axial end positioned axially inward of the axial end faces of the lobe.Type: GrantFiled: January 26, 2017Date of Patent: January 1, 2019Assignee: Roller Bearing Company of America, Inc.Inventors: Roman Malychok, Luda Malychok, Bradley T.

Publication number: 20110103728Abstract: A seal for a bearing has a first and a second circumference, and an anchor portion proximate to the first circumference. A span portion extends from the anchor portion towards the second circumference, and a lip extends from the span portion towards the second circumference. The lip protrudes from the span portion transversely to the span direction. A bearing and seal assembly includes a first ring and a second ring in rotatable engagement with the first ring. The first ring defines a groove and the second ring defines a contact surface. The seal is mounted in the groove, the span portion extending from the anchor portion towards the second ring, and the lip extending from the span portion towards the second ring, engaging the contact surface. The bearing and seal assembly may be used as a pitch bearing and/or a yaw bearing in a wind turbine.Type: ApplicationFiled: October 15, 2010Publication date: May 5, 2011Applicant: ROLLER BEARING COMPANY OF AMERICA, INC.Inventors: John Cowles, Charles Houle, Roman Malychok, Robert Pallini, Serge Bochnovich
