Fafnir Angular Contact Bearing, For Industrial

Product Details

Angular Contact Bearings:Fafnir angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in both directions.The special geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads. Different designs offer contact angles ranging from 20° to 40°. Higher angles provide more axial load capacity for longer service life operating under axial and radial loads.Typical Applications: General industrial Chemical Utilities Agricultural Expanded Options Special lubricants Special cage materials Special preloads Special coatings for corrosion resistance 2MM-WI types with 15° initial contact angle are designed to meet the needs of machine builders for precision bearings which will operate at as low a temperature as possible for a wide range of speeds and operating loads. In order for machines to produce more accurate work at a higher production rate, the bearings must provide a high degree of rigidity in both axial and radial directions while operating a minimum temperatures. For example, precision machining or cutting tools impose heavier loads on bearings than those encountered in precision grinding. In the former, speeds are slower and loads heavier than the latter, where speeds are high and loads light.3MM-WI types, manufactured with 25° contact angle, are for use on applications where the loading on the bearings is predominately thrust — and a high degree of axial rigidity is a definite requirement. Typical applications for these are large vertical rotary surface grinders, horizontal and vertical disc grinders, and thrust bearing applications for heavy duty lathes where the bearings must directly carry extremely high tail stock or chucking pressure.2MM-WO types with 15°-18° initial contact angle are designed for extremely high-speed applications where centrifugal force of the balls is the principal load on the bearing. Unlike the MM-WI type which has a low shoulder outer ring, the 2MM-WO type has full shoulders on both sides of the outer race and a low shoulder on one side of the inner ring.2MM-WN types with 15° initial contact angle are designed to meet the needs of machine manufacturers who require optimum oil flow through the bearings.This design incorporates a low shoulder on the non-thrust side of both the inner and outer rings.2MMV and 3MMV 99100WN types are available with 15° or 25° contact angle variations and have been developed to operate under the demanding requirements of high speed machine tools. They incorporate design features which permit operation at higher speed than standard angular contact ball bearings. The bore, outside diameter, and width are the same as the MM9100 series.HX Types are dimensionally interchangeable with equivalent 9100, 99100 and ISO Series-10 bearings. These designs enable spindle heads to remove more material in less time while maintaining superior machining tolerances. HX bearings come with steel or ceramic ball complements with a 15 degree standard contact angle in a WN construction design.Ballscrew Support Bearings:To meet the requirements of the servo controlled machinery field, Torrington has developed a new series of ball bearings specially designed for ballscrew applications.
