Specifications of TIMKEN Bearing HJ-9211648

The TIMKEN Bearing HJ–9211648 is a cylindrical roller radial bearing in the HJ Series. This bearing is designed for high radial load applications and is constructed from high quality materials for long–lasting performance and reliability. The material structure of the HJ–9211648 consists of two rows of cylindrical rollers, a single outer race and two inner races. The cylindrical rollers are separated by a cage and guided by the inner races. The outer race of the bearing is typically made of steel, and the inner races are made of either chrome steel or brass. The main advantage of the TIMKEN Bearing HJ–9211648 is its ability to handle high radial loads without sacrificing performance. It is also highly resistant to shock and vibration, making it ideal for applications where reliability is important. Additionally, the cylindrical rollers help reduce friction and increase efficiency. The main disadvantage of this bearing is its cost. Since it is made of high quality materials, it is more expensive than other types of bearings. Additionally, it is more difficult to install and maintain due to its intricate design.

TIMKEN Bearing HJ-9211648,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
