The UCF208 Square Flanged Bearing Unit provides significantly greater mounting rigidity than standard two-bolt flange units. The unit consists of a cast-iron 4-bolt housing (F208) and a chrome steel insert ball bearing (UC208). The spherical outer surface of the bearing insert matches the concave internal surface of the housing, giving the unit a self-aligning capability that easily absorbs shaft misalignments and vibrations. Two set screws on the extended inner ring securely lock the bearing to the shaft, preventing slippage during high-torque operations.
Please cross-reference the dimensions below to ensure proper fitment for your structural framework.
Item | Specification |
|---|---|
Model Designation | UCF208 |
Shaft Bore Diameter (d) | 40 mm |
Overall Length/Height (L / A) | 130 mm |
Bolt Hole Center Distance (J / E) | 102 mm |
Overall Unit Width (Z) | 51.2 mm |
Flange Thickness | 15 mm |
Mounting Bolt Size | M12 (1/2 inch) |
Weight | ≈ 1.75 kg - 2.5 kg |
(Note: We also supply inch-size variants of this housing, such as the UCF208-24 (1-1/2 inch bore), upon request.)
Designed for harsh industrial duty cycles, the UCF208 minimizes maintenance downtime and maximizes power transmission efficiency:
Contamination Protection: Features a single-lip contact seal with an outer flinger (slinger seal design), effectively repelling dust, moisture, and debris from entering the raceways.
Easy Relubrication: The cast-iron housing is equipped with a standard grease nipple (zerk fitting), allowing maintenance crews to re-lubricate the bearing easily, extending its service life.
Modular Replacement: The bearing insert and housing are modular. If the bearing wears out, a new insert can be fitted into the existing housing without unbolting the entire assembly from the machine.
Because it can be securely bolted to flat vertical surfaces, the 4-bolt square flange design is heavily utilized in:
Heavy engineering and metallurgical machinery.
Paper manufacturing and printing presses.
Food processing equipment and conveyor belt assemblies.
Agricultural feed mills and HVAC fan systems.
We offer highly responsive supply chain solutions for machinery builders and aftermarket parts distributors.
OEM & Customization: Available with specific precision grades (P0 to P4) and custom packaging based strictly on the buyer's requirement. Stainless steel housings are also available for food-grade environments.
Delivery Time: Fast dispatch with ready goods available within 5 days; bulk/custom orders fulfilled within 5–20 days.
Payment Terms: Flexible international terms including 100% T/T, 30% T/T deposit (balance against B/L or L/C), Western Union, and PayPal.
