UC217-52 Insert Ball Bearing | 3-1/4" Bore, 150mm OD, 85.7mm Width for Heavy Industrial & Agricultural Machinery

📏 Dimensional & Technical Blueprint

• Bearing Series: UC217-52 (Insert Ball Bearing)

• Inner Diameter (Bore): 3-1/4 inches (approx. 82.55 mm)

• Outer Diameter (OD): 150 mm

• Total Width (Inner Ring): 85.7 mm (3.374")

• Material Composition: Premium GCr15 High-Carbon Chrome Steel

• Locking Mechanism: Dual Heavy-Duty Set Screws

• Ring Profile: Extended Wide Inner Ring & Spherical Outer Surface

• Sealing Protection: Dual Industrial Rubber Lip Seals

🛡️ Key Performance Highlights

• Maximum Torque Retention: Twin offset set screws clamp tightly onto large-diameter commercial drive shafts, eliminating rotational play and slip under heavy torsion.

• Heavy Load Endurance: Forged from metallurgical-grade chrome steel, engineered to absorb massive radial loads and maintain stable rotation under continuous friction.

• Housing Alignment Ready: The outer spherical raceway enables smooth pairing with standard pillow block or flange housings, compensating for natural structural deflections.

• Sealed-For-Life Reliability: Factory-packed with heavy-load grease and tightly guarded by dual lip seals to completely block out abrasive dirt, grit, and moisture.

🚜 Target Industries & Applications

• Heavy Agriculture: Large combine harvesters, grain elevators, and tractor auxiliary power drives.

• Bulk Material Handling: High-capacity belt conveyors, mining crushers, and sorting systems.

• Industrial Plant Machinery: Industrial ventilation fans, heavy-duty blowers, and large-scale mechanical power transmission units.
