CARB Toroidal Roller Bearings
CARB toroidal roller bearings exhibit a distinct design that allows for the accommodation of misalignment without increasing stress levels, a feature critical in self-aligning bearing arrangements. These bearings facilitate frictionless axial movement within the non-locating position, enhancing operational flexibility. Furthermore, they are engineered to accommodate higher load capacities, ultimately resulting in a significantly extended service life. Their advanced design and functionality make them indispensable in applications requiring high precision and durability.
- Accommodate Misalignment
CARB toroidal roller bearings exhibit self-aligning capabilities akin to spherical roller bearings and self-aligning ball bearings. - Accommodate Axial Displacement
These bearings effectively manage thermal shaft expansion, similar to cylindrical and needle roller bearings. - Wide Assortment of Dimension Series
CARB bearings are offered with boundary dimensions equivalent to those of spherical roller, self-aligning ball, cylindrical roller, and needle roller bearings. - Long Service Life
The optimized roller profile mitigates stress concentrations at roller ends, enhancing longevity. - Low Friction
Self-guiding rollers minimize friction and associated heat generation. - Improved Wear Resistance
All CARB bearings are engineered as upgraded models for enhanced durability. - Low Noise
These bearings effectively reduce noise and vibration, beneficial in applications such as paper machines and fans. - Long Bearing System Life
In self-aligning configurations, CARB bearings in non-locating positions eliminate internally induced axial forces, providing multiple advantages:- Reduced load extends service life.
- Bearings operate cooler, prolonging lubricant life and extending maintenance intervals.
- Noise and vibration levels are diminished.
CARB Toroidal Roller Bearings are meticulously designed to handle high radial loads while accommodating axial displacement and angular misalignment. These bearings are extensively employed across various industries due to their unique self-aligning capabilities and ability to reduce friction. Engineered for precision and versatility, they are available in an array of designs, variants, and sizes to meet specific application requirements. Typical applications include:
- Industrial transmission

CARB Toroidal Roller Bearings - Designs and Variants
Basic Design Bearings
CARB toroidal roller bearings are designed to accommodate both axial displacement and angular misalignment simultaneously, making them ideal for applications that require high load-carrying capacity while ensuring optimal performance in compact spaces. These bearings are typically used in heavy machinery like paper mills and gearboxes where flexibility and load balance are critical.
Sealed Bearings
Sealed CARB toroidal roller bearings offer the added benefit of protecting the bearing components from contaminants like dust, dirt, and moisture. The sealed design enhances the longevity of the bearing by maintaining lubrication, making them suitable for harsh environments such as mining, construction, and marine applications, where exposure to external elements can compromise performance.
