NMB - SBT20 | Spherical Plain Bearing | 20 × 46 × 25 mm

Details

NMB SBT20 is a spherical plain bearing with inner diameter 20 mm, outer diameter 46 mm and width 25 mm. Additional specifications include bore type CYLINDRICAL and lubrication STANDARD.

The SBT bearing is a radial spherical plain bearing manufactured by NMB. These heavy-duty components are engineered to handle high static and dynamic radial loads while accommodating misalignment. It utilizes a fractured outer ring mechanism in this series. This design slightly deflects the outer race within its elastic limit during manufacturing to securely "pop in" the larger inner ball. The integrated PTFE fabric liner serves as a permanent dry-film lubricant. It eliminates the need for manual re-greasing, slashes maintenance overhead, and prevents typical metal-on-metal failure modes such as friction-induced seizure, galling, and fretting fatigue. Material : Constructed with a through-hardened SUS440C stainless steel ball, a high-strength SUS410 stainless steel outer race. Features are : Oscillatory Optimization, Broad Thermal Operating Range, Precision Press-Fit Concentricity, Complete Chemical Isolation, Precision Press-Fit Concentricity, Lowered Procurement and Replacement Lifecycles. Applications : Aerospace & Aviation Systems, Packaging & Material Handling, Pneumatic & Hydraulic Cylinders, Medical & Laboratory Instrumentation, Semiconductor Manufacturing & Electronics Printing, Renewable Energy & Power Infrastructure.
