About this product
Clevis Cylinders with Spherical Bearings represent the premium solution for applications involving varying load angles and angular misalignment. The spherical bearing — a precision ball-and-socket joint integrated into the clevis — allows the cylinder to self-align in multiple planes simultaneously.
While standard clevis mounts accommodate misalignment in one plane (the pivot plane), spherical bearings handle misalignment in all directions. This is critical in applications where installation imprecision, frame deflection, or dynamic load changes create complex multi-axis forces on the cylinder.
By allowing the cylinder to float and self-center under load, spherical bearings dramatically reduce side loading on the piston rod, seals, and bearings — extending service life, reducing maintenance frequency, and preventing premature seal failure. This makes them the preferred choice for high-value, high-reliability applications.
KBR Engineers manufactures spherical bearing cylinders with precision-ground bearing surfaces, hardened races, and maintenance-free or greaseable bearing options. Each cylinder is built with precision-honed barrels, chrome-plated rods, and premium sealing systems.
Manufacturing Range
KBR Engineers manufactures a wide range of custom-built hydraulic cylinders to meet diverse industrial requirements.
