Exploring Core Features of PROFAB SS Spherical Bearings
360° Multi-directional self-adjustment
Automatically compensates for axial and angular misalignment, ensuring smooth operation without sticking and stress concentration.
High load carrying capacity
Designed to withstand heavy radial and axial forces, suitable for highly dynamic scenarios such as robotics, aerospace and industrial machinery.
Excellent Corrosion and Wear Resistance
Precision machined from 304/316 stainless steel, it resists salt spray, chemical corrosion and abrasion for longer service life.
Flexible lubrication
Optional self-lubricating PTFE lining or lubrication programme with greasing device to meet different maintenance cycle requirements.
Superior PROFAB Machining - For High-Quality SS Spherical Bearings
Machining centres utilise the latest CNC technology to turn and mill stainless steel spherical bearing housings and inner rings with exceptional precision. The second stage is strengthening the material by quenching or ageing heat treatment. The third stage is passivation, which is achieved through pickling to create a dense protective layer.
For the assembly step, self-lubricating PTFE linings or grease lubrication systems with dust-proof seals are fitted to different models. Dimensional and concentricity checks are done in batches on a CMM, and corrosion resistance is tested with an ASTM B117 salt spray test.
Profab spherical bearings are kept with quality and reliability in mind, thus calibrated to specific torque values.
