At Fastenal Machinery Corporation, we apply engineering experience and expertise to solve the world's most unique bearing challenges.Thin bearing solutions save weight, create space, reduce friction, increase design flexibility, and provide excellent running accuracy.
Bearing 7048 KOYO has been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads. Furthermore, since an axial component is generated when a radial load is applied, these bearings are generally used in pairs, triplex sets, quadruplex sets, or multiplex sets.Fastenal Machinery Corporation offers one of the most comprehensive ranges of angular contact ball bearings available.
Bearing 7048 KOYO 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. Bearing 7048 KOYO can accommodate thrust in both directions.
Fastenal Machinery Corporation became the authorized distributor of NACHI in 2001. Bearing Scope: Deep Groove Ball Bearing, Angular Contact Ball Bearing, Four Point Contact Ball Bearing, Self-Aligning Ball Bearing, Thrust Ball Bearing, 7048 Angular Contact Ball Bearings 2018 latest NACHI,Cylindrical Roller Bearing, Needle Roller Bearing, Taper Roller Bearing, NACHI Bearings, Spherical Roller Bearing, Thrust Roller Bearing, Pillow Block Bearing, Rod End Bearing, Bearing Housings etc.
Due to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. 7048 Angular Contact Ball Bearings 2018 latest NACHI are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe,NACHI Bearings may have ceramic balls creating a hybrid bearing.
Single Versus Double Row Angular Contact Ball Bearings
As previously mentioned, 7048 Angular Contact Ball Bearings 2018 latest NACHI are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. This can bee done by matching up multiple single row bearings or by utilizing double row angular contact bearings which may offer some econmic benefits. However, utilizing multiple single sow 7048 Angular Contact Ball Bearings 2018 latest NACHI can offer greater design flexibility and performance in many cases. For information about the more than 100 different double row angular contact bearings available from AST please visit our web page entitled, "Double Row Angular Contact Ball Bearings."
NACHI Bearings are self-retaining units with solid inner and outer rings and ball and cage assemblies with polyamide, sheet steel or brass cages. The raceways of the inner and outer rings are offset in relation to 7048 Angular Contact Ball Bearings 2018 latest NACHI each other in the direction of the bearing axis. The bearings are available in open and sealed versions. 7048 Angular Contact Ball Bearings 2018 latest NACHI self-alignment capacity is very small.
