PMK Belt Screw Bearing Cartridges – Type BD are precision-engineered bearing units featuring a compact, preloaded bearing arrangement optimized for belt and screw-driven spindle assemblies.

These cartridges employ paired angular-contact bearings in a face-to-face (BD) configuration, providing reliable axial rigidity and smooth rotational performance under varying load conditions. The modular, sealed design enables easy installation and replacement, reducing downtime in high-precision machine tools and automation systems.

Key Benefits

• Performance: face-to-face (BD) bearing configuration ensures accurate axial alignment and high load capacity.
• Precision: factory-preloaded bearing pairs deliver consistent positioning accuracy and low frictional torque.
• Rigidity: robust cartridge housing maintains stable alignment under axial and radial loads.
• Ease of Assembly: ready-to-mount modular design simplifies integration into screw and spindle drive systems.
• Reliability: greased and sealed construction supports long service life with minimal maintenance.

Applications

• Ball screw and spindle end-support assemblies.
• Automation systems, positioning units, and feed drives.
• High-precision CNC machines and rotary mechanisms.
• Retrofit and OEM bearing cartridge replacements.
