Tapered Roller Bearing 30311

The specific of tapered roller bearing 30311

Bearing type:tapered roller bearing 30311 

Bore Size: 55 mm 

Outside Diameter: 120 mm 

Width/Thickness:31.5 mm

Dimensions:55x120x31.5 mm

Weight: 1.63Kg

Precision Rating: P0,P6,P5

Seals Type: OPEN 

Place of Origin: China (Mainland) 

Material:chrome steel or carbon steel or stainless steel

Features:

• Tapered roller bearings comprise of four basic components that include inner ring, outer ring, tapered rollers and cage

• Under normal usage conditions, the cage spaces & retains rollers on inner ring or cone and rest of elements carry the load

• Cone, rollers as well as cage are referred to as cone assembly

• The cup (outer ring) is usually separable from cone assembly

Available Configurations: 

These come in variety of configurations like: 

• Single-row

• Two-row

• Four-row

• Thrust bearing assemblies

• Materials used for roller bearings are either alloy/low carbon steels

• Carbon & alloys are added for ensuring proper combination of hard fatigue resistant case as well as tough ductile core

• Tapered roller bearings have inherent advantages of being adjustable and these can be set to approach optimum performance (in almost any applications)

• For selecting right roller bearing, one must determine desired bearing life as well as a sufficient basic dynamic load rating so as to meet that life requirement

Application:

Automobile, machine tools, motor, instrument, construction machines,railroad cars, agricultural machinery and all kinds of professional machinery

Advantages:

Automated roller bearing setting techniques also offer many advantages like:

• Reduced setting time

• Reduced assembly cost

• Reliable setting
