Engineered for Heavy Radial Loads
As a specialized bearing manufacturer, Tedin produces precision cylindrical roller bearings designed to manage heavy radial loads under high-speed operations. Because the cylindrical rollers are in linear contact with the raceways, they offer greater radial load capacity compared to standard ball bearings while maintaining low friction. Whether you need standard single row designs or heavy-duty multi-row configurations, our products ensure stable performance in demanding industrial environments.

Frequently Asked Questions
- NU series: two ribs on the outer ring and no ribs on the inner ring; suitable for radial loads and axial displacement.
- NJ series: one rib on the inner ring; can locate the shaft in one axial direction.
- NUP series: fixed rib and loose rib ring; can locate the shaft axially in both directions.
Most cylindrical roller bearings are designed mainly for radial loads. NJ designs can accommodate axial load in one direction, while NUP or NH designs can locate the shaft in both directions under limited axial loads. For high thrust loads, a separate thrust bearing or another bearing arrangement is recommended.
CN is used for standard conditions. C3 or C4 clearance is often selected for high speeds, high temperatures, tight interference fits or heavy-duty equipment where thermal expansion must be considered.
Yes. TEDIN can support custom dimensions, precision classes, internal clearance, cage materials, heat treatment, coatings and large-size designs for applications such as rolling mills, gearboxes, machine tools and heavy industrial equipment.
