Product Description

China Factory Wholesale High Quality Single Row Inch Tapered Roller Bearing 30305X2B 30306X2B 30307C 30308D 30309X2B

    Tapered roller bearings are separated bearings, and the inner and outer rings of the bearings are equipped with tapered raceways. This kind of bearing is divided into single row, double row and four row tapered roller bearings and other different structural types according to the number of rows of rollers installed. Single-row tapered roller bearings can withstand radial loads and axial loads in a single direction. When the bearing bears the radial load, an axial component force will be generated, so it is necessary to balance it with another bearing that can withstand the axial force in the opposite directionTapered roller bearing refers to the radial thrust type rolling bearing whose rolling body is a tapered roller.

    There are small cone angles and large cone angles. The small cone Angle mainly bears the radial and axial combined loads mainly based on radial loads, often used in double, reverse installation, the inner and outer seat rings can be installed respectively, and the radial and axial clearance can be adjusted during installation and use. The large cone Angle mainly bears axial and radial combined loads based on axial loads, and is generally not used to bear pure axial loads alone, but can be used to bear pure radial loads when it is configured (the same name is relatively installed).

    Tapered roller bearings mainly bear radial and axial combined loads. The bearing capacity depends on the raceway Angle of the outer ring, and the greater the Angle, the greater the bearing capacity. This type of bearing is a separate type of bearing, which is divided into single row, double row and four row tapered roller bearings according to the number of rows of rolling elements in the bearing. Single-row tapered roller bearing clearance needs to be adjusted by the user during installation; Double-row and four-row tapered roller bearing clearance has been set according to user requirements when the product is delivered, and does not require user adjustment.

Product Parameters

Tapered roller bearings have a conical inner ring and an outer ring raceway, and the tapered roller is arranged between the two. The projected lines of all conical surfaces meet at the same point on the bearing axis. This design makes tapered roller bearings particularly suitable for bearing combined (radial and axial) loads. The axial load capacity of the bearing is mostly determined by the contact Angle α. The larger the alpha Angle, the higher the axial load capacity. The Angle size is expressed by calculating coefficient e. The greater the e value, the greater the contact Angle, and the greater the applicability of the bearing to bear the axial load. Tapred roller bearings are usually of separate type, that is, a tapered inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the tapered outer ring (outer ring).

Features:

 

Simple internal structure, low friction and high limiting speed, mainly bear radial direction load. Deep groove ball bearing can obtain angular contact capability when increasing radial clearance, to take combined load of both axial and radial directions. When the thrust ball bearing is not appropriate for some high speed applications, deep groove ball bearing may be an alternative choice to afford axial loads.
 

Application introduction:
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.

Giant bearings are widely used in automobiles, motorcycles, motor, electric tools, textile machinery,machine tools, construction equipment and transmission equipment, and other fields. 

Giant bearings also are widely used in household appliances and office equipment, such as refrigerators,air conditioners, washing machines, microwave ovens, lampblack machine, vacuum cleaners, sewing machines, massage chair and fitness equipment and other fields.
 

How to expand the lifetime?

1. The installation is correct, that affects precision, life, performance. And fill the bearing with lubricant after installation.

2. Don't allow strong impact, such as hammer striking, transfer roller pressure

3. Use the accurate installation tool, avoid to use cloth kind and short fibers

4. Lubricate the bearing to avoid rust with high quality mineral oil, especially in summer

5. General inspection, such as the surrounding temperature, vibrate, noise inspection

6. Keep bearing cleaning from dirt, dust, pollutant, moisture.

7. Bearing should not be ultra cooled.
