PRODUCT

Tapered roller bearings 32300 series has tapered inner and outer ring raceways and tapered rollers.They are designed to accommodate combined loads, i.e simultaneously acting radial and axial loads.The projection lines of the raceways meet at a common point on the bearing axis to provide true rolling and low friction.The axial load carrying capacity of tapered roller bearings increases with increasing contact angle.The size of the angle is related to the calculation factor, the larger the value , the larger the contact angle.A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

 

Tapered roller bearings have pressed steel cages, however, large-sized bearings use machined type cages while smaller sizes sometimes use plastic cages depending on the application.

 

And the suffixes are listed as follows:

B Contact angle greater than the standard design

HA3 Case-hardened inner ring

HA1 Case-hardened inner and outer ring

J Stamped steel cage, roller centered

Q Optimized contact geometry and surface finish

X Boundary dimensions changed to conform to ISO

TN9 Class fiber reinforced PA66 cage,roller centered

CLN Reduced tolerance for ring widths and total width in accordance with ISO tolerance class 6X

CLO Accuracy to ABMA tolerance class 0 for inch bearings

CLOO Accuracy to ABMA tolerance class 00 for inch bearings

CL7C High performance design for Pinion bearing

 

Application

The taper roller bearings 32300 series are widely used in mining equipment, oil field equipment, cranes and hoists, speed reducers, sheaves, coupling equipment, motorcycle wheels and so on.
