Specifications of TIMKEN Bearing HJ-10412840

The TIMKEN Cylindrical Roller Radial Bearings – HJ Series HJ-10412840 is a single row cylindrical roller bearing that is used for applications that require radial load and axial load in both directions.
This bearing is available in sizes ranging from 100 mm ID to 200 mm ID and has an outer diameter of 2.5 inches.
The material used to construct this bearing is high-quality steel, which provides strength and durability.
The structure of this bearing is designed with a single row of rolling elements that are guided by two inner rings and two outer rings. This design allows for even load distribution and helps to reduce wear and tear.
The primary usage of this bearing is for heavy radial and axial loads in both directions. This bearing is used in a variety of industries, including automotive, industrial, and construction, due to its high load capacity and low friction.
The advantages of this bearing are that it is durable, reliable, and has a high load capacity. Additionally, it is easy to install and maintain and can handle high speeds.
The disadvantages of this bearing are that it is not suitable for high-precision applications due to its loose tolerances, and it is more expensive compared to other types of

TIMKEN Bearing HJ-10412840,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
