Tapered roller bearing are designed such that cup, cone and rollers have tapered surfaces whose apexes converge at a common point on the bearing axis. Along with metric series bearing, inch series bearing are also available. This type of bearing is suitable for applications that involve heavy or impact loading.
.
- Ability to carry radial and axial load in one direction, because an axial component of force is produced when this type of bearing is loaded radially, two bearings are used together facing one another or two or more bearings are matched and used
- .
- There are the standard, medium and steep type which are different in contact angle size, medium tapered metric series bearing are identified by the supplementary code "C" which is added as a suffix to bearing numbers
- .
- Bearing whose cup width, cup small inside diameter and contact angle are determined in accordance with ISO 355 specifications are identified by the supplementary code "J" as suffix
How do I choose the right type of bearing for my application?
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.
