Applications
Custom Bearings for Demanding Industrial Applications
TEDIN custom cylindrical roller bearings are developed for heavy-load, high-speed and non-standard working conditions.
Metallurgical Equipment
Rolling mills, continuous casting and heavy-duty transmission systems.
Mining Machinery
Crushers, vibrating screens, conveyors and shock-load equipment.
Industrial Gearboxes
Gearboxes requiring high radial load capacity and stable operation.
Typical Custom Projects We Review
Custom cylindrical roller bearing requests often come from maintenance, replacement or special equipment projects where a standard catalog bearing is not suitable.
Non-standard bearing for a heavy-duty gearbox
The original cylindrical roller bearing is difficult to source, and standard catalog bearings do not match the required dimensions.
TEDIN reviews the old model, bearing size, shaft fit, housing fit and working load before confirming a possible custom solution.
Small-batch bearings made according to drawing
A machinery builder needs several cylindrical roller bearings for a prototype or test machine before moving to regular purchasing.
Dimensions, cage type, clearance, precision grade and application speed are checked carefully before production.
Technical review for a hard-to-source imported bearing
The existing imported bearing has a long lead time or is no longer easy to purchase for maintenance projects.
TEDIN compares the bearing marking, dimensions, internal structure, clearance, cage design and application conditions.
For a faster review: please send the bearing model, drawing or sample photos, bore diameter, outer diameter, width, quantity, precision grade and application details.
KOCKS-Type Rod Mill Stand Bearing Replacement Case
A steel mill needed a reliable replacement bearing solution for a KOCKS-type rod mill stand housing. TEDIN supplied a custom bearing set based on the equipment structure, fitting dimensions and working conditions of the rod mill stand.
This case shows TEDIN's work in rolling mill maintenance projects where standard bearing references are not enough and the replacement set needs to match the existing stand arrangement.
