The JHM88540/JHM88513 is a inch tapered roller bearing with a 30.000 mm bore, 72.000 mm outer diameter and 27.783 mm width. Because the roller and raceway surfaces meet on a common apex, it carries combined radial and axial load and keeps the shaft in position under load.
Typical uses are steel plants. Every bearing is dimensionally inspected to ISO 492 before dispatch, and the JHM88540/JHM88513 can be supplied under neutral packing, custom packaging or a full private label set.
Product Description
The JHM88540/JHM88513 is a inch tapered roller bearing with a 30.000 mm bore, 72.000 mm outer diameter and 27.783 mm width. Tapered roller bearings carry combined radial and axial load because the roller and raceway surfaces meet on a common apex, so the rollers stay in true rolling contact along the whole contact length instead of skidding at the ends.
This makes the JHM88540/JHM88513 a practical choice for steel plants, where the shaft has to hold its position under load across a long service interval. If your duty point runs at high speed, under heavy shock load, or in an extreme-temperature environment, confirm the selection with us before ordering — a tapered roller bearing is a locating bearing and its mounting preload has to suit the application.

| Axial setting | Tapered roller bearings are locating bearings — set the axial clearance or preload to the value the application calls for |
| Lubrication | Use the grease or oil specified for the duty point; keep the seal and surrounding area clean during fitting |
| Storage | Keep in the original packaging, dry and free from vibration |
| Operating limits | Not intended for extreme temperature or severe shock loading — confirm the duty point before selection |
