R Series bearings are single row, inch series bearings available from 1/8 through 1-1/2 inch bore sizes. The Conrad construction of these bearings enables them to accept thrust as well as radial load. The 1600 series bearings are designed to be dimensionally interchangeable with standard domestic inch series bearings. 6000 Series, extra light bearings are normally used in applications where space limitations are a primary consideration and shaft sizes are relatively large. 6200 Series bearings feature deep, honed raceways, resulting in a perfectly balanced bearing. Functionally similar to the 6200 series, the 6300 Series is produced with a larger ball complement and heavier races allowing greater radial, thrust and combined load capacity for a given bore size. Numerous special applications require non-standard ball bearings. V Groove Guide Wheel bearings are precision ground, double row, angular contact bearings. Characterized by a low coefficient of friction and low torque, Industrial Airframe bearings are designed for applications of oscillating motion or slow intermittent rotation.
