IMPROVED ROLLER BEARING

摘要

Conventional recirculating roller bearings often do not travel precisely perpendicular to the axis of the race. This roller skewing raises the level of friction in the system. The present invention provides an improved recirculating roller bearing (10) and a roller element (12) therefor in which the end members (18) of the rollers (12) have an axial bore (20) within a portion of the cylindrical end member (18). The axial bore extends between 30% and 50% of the length, and between 20% and 30% of the diameter of the cylindrical end member (18). This configuration effectively neutralizes the effects of roller skewing by reducing the amount of corrective force needed to realign a roller into a straight rolling trajectory.
