SKF SNL 505 52 - Durable Split Bearing Housing for Industrial Applications

Applications

The SKF SNL 505 52 bearing housing is a high-quality split plummer block designed for mounting self-aligning ball or spherical roller bearings. Engineered for shafts with a 52 mm diameter, it ensures reliable bearing support, long service life, and simplified maintenance in demanding industrial environments.

It is widely used in conveyors, pumps, electric motors, fans, compressors, agricultural machinery, and heavy-duty industrial drives. The split design allows for easy assembly and disassembly of the bearing without removing the shaft — reducing downtime and maintenance costs.

Advantages

• Original SKF design - ensures precise fit, perfect alignment, and compatibility with a wide range of bearing types.

• High-strength cast iron housing - guarantees resistance to shock loads, vibrations, and corrosion.

• Quick installation and maintenance - two-piece (split) design makes bearing replacement simple and efficient.

• Excellent sealing performance - supports various sealing options (labyrinth, felt, or cassette seals) for superior protection against dust, dirt, and moisture.

• Universal use - compatible with self-aligning and spherical roller bearings, suitable for multiple industrial sectors.
