Rich Stocks Timken NSK R25-36ag 25*54*17.3mm Radial Taper Roller Bearing for Automobile
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 features:
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. Tapered 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).
Application introduction:
Tapered roller bearings are widely used in automobile, rolling mill, mining, metallurgy, plastic machinery and other industries.
