Timken HJ-729636 is a single row cylindrical roller bearing (CRB) for general industrial applications. This bearing features a dynamic load rating of 285 kN (64,000 lbf) and a static load rating of 517 kN (116,000 lbf), suitable for moderate to heavy radial loads. It is designed for applications requiring high radial capacity and rigidity, such as in electric motors, gear reducers, and industrial machinery where precise shaft location is managed by the adjacent bearing arrangement.

- Clearance fit suggested for outer ring when housing is stationary relative to load.
- Tight transition fit suggested if housing rotates relative to load.
- Consult your Timken representative for oscillating applications (e.g., low radial-clearance concerns).
- Unmarked end of outer ring should be assembled against housing shoulder to clear maximum allowed housing fillet (ras max).
- Meets Military Standard MS 51961.

Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
