CARB Series Toroidal Roller Bearing combines the self-aligning capability of spherical roller bearings with the axial displacement accommodation of cylindrical roller bearings. It is designed to withstand high radial loads while allowing free axial movement of the shaft, effectively reducing additional stress caused by thermal expansion, misalignment, or shaft deflection.
Building on these advantages, JRZC CARB series bearings are manufactured using high-purity bearing steel and optimized roller profiles, significantly enhancing load capacity and fatigue life. With precision heat treatment and strict machining control, the bearings deliver low friction, low noise, and low operating temperature. In addition, multiple internal clearance and surface treatment options are available to meet the demands of heavy-duty, long-life, and complex operating conditions, making them an ideal solution for paper-making machinery, wind power, metallurgy, and other heavy industrial applications.

CARB Series Toroidal Roller Bearings offer outstanding application advantages in demanding industrial environments. Their ability to accommodate axial displacement without generating axial forces simplifies bearing arrangements and reduces stress on shafts and housings. The self-aligning function effectively compensates for installation errors and shaft deflection, ensuring stable operation even under harsh conditions.
Combined with high radial load capacity, low friction, and reduced operating temperature, CARB bearings help extend service life, minimize maintenance requirements, and improve overall equipment reliability, making them especially suitable for paper machines, wind turbines, heavy gearboxes, and large rotating machinery.
FAQ
A: A CARB toroidal roller bearing is a special type of roller bearing that combines the self-aligning capability of spherical roller bearings with the axial displacement function of cylindrical roller bearings. It can carry high radial loads while allowing free axial movement of the shaft.
A: CARB bearings offer high radial load capacity, automatic self-alignment, axial displacement without axial force, low friction, and long service life, making them ideal for demanding industrial applications.
A: CARB bearings are primarily designed for radial loads. They do not support significant axial loads and are usually used together with a locating bearing to control axial positioning.
