Specifications of TIMKEN Bearing HJ-12415448

Description: The TIMKEN HJ-12415448 is a cylindrical roller radial bearing. It is designed to withstand high radial loads and is commonly used in heavy-duty applications like conveyors, gear boxes, and other industrial machinery.
Size: The bearing has an inner diameter of 12.000 inches (304.8mm) and an outer diameter of 15.000 inches (381mm).
Material: The bearing is made of high-quality steel for strength and durability.
Structure: The bearing is composed of two rows of cylindrical rollers that are held in place by two outer rings and two inner rings.
Usage: The TIMKEN HJ-12415448 is typically used in applications requiring high radial loads such as conveyors, gear boxes, and other heavy-duty industrial machinery.
Advantages: The bearing is designed for high radial loads and is made of high-quality steel for strength and durability. It also has a low coefficient of friction which helps to reduce power consumption and wear.
Disadvantages: The bearing is not suitable for applications requiring high axial loads due to its design

TIMKEN Bearing HJ-12415448,Cylindrical Roller Radial Bearings - HJ Series. These bearings carry radial load only and can accommodate both expansion and contraction. The relative axial displacement of one ring to the other occurs with minimum friction while the bearing is rotating. Type N bearings may be used in one or two positions for shaft support if other means of axial location are provided. The outer ring has a cylindrical bore without ribs and the inner ring incorporates two ribs.

Size range: 80 mm to 2000 mm OD

Design Attributes
Design has a cylindrical outer ring and two ribs on the inner ring, making type N bearings well suited for use as floating bearings.
Separable components simplify mounting and removal.
Accommodates axial expansion and contraction.
Provides axial displacement between rings with minimum friction while rotating.
Supports heavy radial loads.
Not suitable for applications with thrust loads.

Applications
Cement making equipment such as crushers; vertical, ball and rolling mills; conveyor drives; gear reducers, spherical pillow blocks; trunnions and rotary kilns Power generation equipment such as pulverize-rs, gearboxes and gear drives Oilfield equipment such as mud pumps, draw-works, swivels, block hooks, crown blocks, traveling blocks and top drives
