Spherical roller bearings
Spherical Roller Bearings are designed to provide outstanding reliability and load-carrying capacity in heavy-duty and misalignment-prone applications. With double rows of barrel-shaped rollers and a spherical outer ring raceway, these bearings can automatically accommodate angular misalignment caused by shaft deflection or mounting errors, while supporting very high radial loads and significant axial loads in both directions. Their robust internal structure ensures stable performance under shock loads, vibration, and harsh operating conditions.
Within this product range, Spherical Roller Bearings offer excellent versatility for applications requiring combined radial and axial load capacity, while CARB Toroidal Roller Bearings represent an advanced solution for systems exposed to axial displacement. CARB bearings combine the self-aligning capability of spherical roller bearings with the ability to accommodate axial movement within the bearing itself, effectively eliminating internal axial stresses. This makes them ideal for applications where thermal expansion, long shafts, or floating bearing arrangements are critical.
Manufactured from premium-grade bearing steel and produced using advanced heat treatment and precision machining processes, both Spherical Roller Bearings and CARB Toroidal Roller Bearings deliver superior wear resistance, extended service life, and low maintenance requirements. They are widely used in industries such as mining, cement, metallurgy, paper making, wind energy, and heavy machinery, where high reliability, operational stability, and long-term performance are essential.

Spherical roller bearings
Material: GCr15/GCr15SiMn/G20Cr2Ni4A
Features: Spherical roller bearings, whose inner ringss have two raceways, and outer race-ways are spherical. The centers of curvature of outer raceways are alse the bearing centers. The bearings possess self-aligining performance, the permissible disalignment angle is 1-2.5°, and can be used in certain permanent deflective application.
Application: rolling mills, paper making machines,power-driven gears, shipping and so on.
Advantage: These bearings are able to carry high radial loads, as well as axial loads at the same time, but not pure axial loads, the axial carrying bearing will be needed if axial loads were higher. The contact between rollers and raceways are so close, so the friction is higher than cylindrical roller bearings, and their limiting speed is lower.
