Self Lube Units

Self-lube bearing units are pre-assembled, ready-to-mount components combining a sealed ball bearing insert with a housing, designed for easy installation on standard shafts.

featuring self-aligning capabilities (spherical outer surface/housing fit) to handle minor mounting errors, and often including a re-lubrication port for extended life in machinery like conveyors, farm equipment, and industrial automation. They come in various housing styles (pillow block, flanged, take-up) and materials (cast iron, plastic, stainless steel) for diverse industrial needs.  

Key Components & Features:

    Bearing Insert : A sealed radial ball bearing, often with a wide inner ring for easy shaft mounting, using set screws, an eccentric locking collar, or an adapter sleeve. 

Housing: A rigid structure (cast iron, pressed steel, thermoplastic) with a spherical inner surface that matches the bearing's outer surface, allowing for self-alignment. 

Self-Alignment : The spherical fit compensates for initial angular misalignment during assembly, crucial for fabricated structures.

Sealing: Effective seals protect the bearing from contaminants, with options like flingers or triple-lip seals for harsh environments. 

Locking Mechanisms: Eccentric collars or set screws secure the bearing onto the shaft. 

Regreasing Facility: Most cast iron units have a grease nipple for adding lubricant.

Common Housing Types:

    Pillow Blocks: Simple, common blocks for mounting on flat surfaces.
    Flanged Units (Square/Oval): Have flanges for direct bolting to machine frames, ideal for limited space.
    Take-Up Units: Used in conveyor systems to adjust belt tension. 

Applications:

    Agriculture
    Material handling
    Construction machinery
    Food processing
    Manufacturing & Automation
