SIN MARCA SC404 Unit Insert Bearing | 20mm Bore Set Screw Pillow Block Insert
The SIN MARCA SC404 is a robust, standard-duty unit bearing insert designed for industrial applications requiring reliable performance and easy maintenance. Constructed from high-quality chrome steel, this bearing features a spherical outer ring that allows for initial self-alignment within a corresponding pillow block (P series) or flanged housing (F series). The 20mm (d=20mm) bore is secured firmly to the shaft using two integrated set screws, ensuring maximum rotational stability and minimizing slip under moderate load conditions. Its deep groove ball bearing construction facilitates high-speed capability while the robust R-seal configuration provides excellent protection against dust, moisture, and contamination, making the SC404 ideal for demanding operating environments like agricultural machinery, conveyor systems, and industrial fans.
As part of the SIN MARCA industrial line, the SC404 offers exceptional cost-effectiveness without compromising critical operational integrity. This unit is dimensionally interchangeable with major industry standards (e.g., UC204 equivalents), ensuring seamless integration into existing maintenance, repair, and operations (MRO) schedules. Pre-lubricated with high-grade industrial grease and featuring a convenient relubrication port, the SC404 is engineered for extended service life, reducing downtime and overall cost of ownership. Choose SIN MARCA for reliable, budget-conscious solutions that keep your machinery running efficiently.
