Metric Size Chrome Steel Tapered Roller Bearings
Brief introduction: Taper roller bearing are generally used to support combined load mainly consisting of radial load. Their cups are separable for easy assembling. During mounting and using, radial clearance and axial clearance can be adjusted and preloaded mounting can be made. Taper roller bearing are uniquely designed to manage both thrust and radial loads on rotating shafts and in housings.Taper roller bearing are designed to carry both thrust and radial loads and consist of four components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer. Taper roller bearing mainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring’s raceway. The bigger the contact angle is, the greater the capacity will be. Taper roller bearing the angle between the outer raceway generatrix and line, the bearing can bearing heavy load and other Tappered Roller Bearings, it mainly bears joint load based on one way axial load,but not only radial load. Taper roller bearings have tapered inner and outer ring raceways, The tapered roller is in the middle of the two raceways. This kind of bearings is usually separatable, namely the retainer, inner ring and outer ring can be installed apart. They can withstand immense radial direction load and certain axial load. They are designed in different sizes and styles to meet all kinds of functions.
Types: 1.Single-row tapered roller bearings 2.Double-row tapered roller bearings 3.Four-row tapered roller bearings 4.Double, four-row tapered roller bearings with multi-seal
Typical applications: Tapered roller bearings are widely applied to machine tool spindles, gear reduction units, automotive transaxles, transmissions, rolling mill, mining, metallurgical industry, plastic machinery, home appliances, electric motors, pumps, machinery and other automotive components.
Advantages: 1.high speed and high precision 2.long service lifetime 3.lowest noise and good performance
