Detailed Product Description
GCr15 NTN Tapered Roller Bearing 30000 Series With P0 / P4 / P5 / P6 Precision Rating
Introduction
Tapered roller bearing main bear with radial primarily, the axial union load. Bearing outer ring rolling
bearingcapacity depends on the way Angle, the greater the carrying capacity of the larger Angle. This type
of bearingsis bearing separation, according to the bearing of the roller column number into a single, double
rows and fourrows circular cone roller bearings. The single row circular cone roller bearing clearance to
users in theinstallation to adjust; Double rows and four rows circular cone roller bearings clearance has
set up a file in the products based on user requirements given, don't need to adjust by the user.
Tapered roller bearings are usually separated model, namely the belt roller and maintain a component of
the inner circle, circle of inner cone components and cone outside (outer) can apart installation.
Tapered roller bearings widely used in automotive, rolling mill, mining, metallurgical, plastic machinery, etc.
