Specifications of TIMKEN Bearing HJ-729636

TIMKEN Cylindrical Roller Radial Bearings – HJ Series HJ-729636 is a bearing designed to support heavy radial loads. It has a single-row cylindrical roller design, which allows for both high radial and axial loads. The bearing features a cage-guided design, which helps to reduce friction and heat buildup. It is constructed with an outer ring that has a thick wall and double-lip seals. Its inner ring is ribbed for extra rigidity and strength.
Size: It has an outside diameter of 7.874 inches, an inside diameter of 6.299 inches, and a width of 2.835 inches
Material: The bearing is constructed from high-grade carbon steel and is case-hardened for superior wear resistance.
Structure: The bearing has a single-row cylindrical roller design, which allows for both high radial and axial loads. It has a cage-guided design, which helps to reduce friction and heat buildup. The outer ring has a thick wall and double-lip seals, which keep contaminants out and help to maintain lubrication.

TIMKEN Bearing HJ-729636,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
