Key Features (Official)
- Hex Socket Head (A): Equipped with a hexagonal socket on the stud head, enabling secure mounting with a hex wrench in confined spaces.
- Double‑Lip Seals (UU): Provides effective dust and contamination protection, retaining factory‑preloaded grease for extended service life.
- Cylindrical Outer Ring: Delivers stable, uniform contact with flat cam surfaces for smooth rolling motion.
- Caged Needle Rollers: Ensures low‑friction rotation, high load capacity, and stable operation at moderate speeds.
- Pre‑Lubricated: Factory‑filled with grease for immediate use; no relubrication port is provided.
- High‑Carbon Steel Construction: Offers excellent rigidity, wear resistance, and durability for industrial applications.
