Product Detail
DKFL UCP 207 Pillow Block Unit Heavy-Duty 35mm Bore | Solid Base Housing (P207) | UC207 Insert Bearing
The DKFL UCP 207 is an ultra-durable, pre-assembled mechanical unit featuring proprietary "Solid Base" technology. Engineered for 35mm shafts, this unit is designed to absorb high radial loads, suppress mechanical shock, and maintain structural integrity in the most demanding industrial environments.
Anatomy and Technical Components of DKFL UCP 207
The DKFL UCP 207 is a fully integrated mechanical system, consisting of two precisely matched components engineered for seamless performance:
- Solid Base Cast Iron Housing (P207): A high-density cast iron housing featuring a reinforced, solid-base structure. Includes a precision-machined spherical concave seat, heavy-duty mounting slots, and an angled brass grease nipple for efficient maintenance.
- Self-Aligning Insert Bearing (UC207): A heavy-duty deep-groove ball bearing with a convex spherical outer ring and an extended inner ring, secured to the 35mm shaft via two hardened 120-degree set screws.
Self-Alignment Capability: The spherical interface between the P207 housing and the UC207 insert allows for angular misalignment correction of ±2° to ±3°. This technical advantage prevents damaging stress concentration on the balls and raceways caused by structural frame inaccuracies or shaft deflection.
The Solid Base Advantage vs. Hollow Base Housings
Unlike standard market units built with thin-walled, hollow bases (Hollow Base), the DKFL P207 housing is engineered with solid-base casting technology:
Drawbacks of Hollow Base Housings:
Susceptibility to foot breakage during tightening, deformation of the spherical seat under dynamic loads, accumulation of sludge/moisture beneath the base, and increased resonance at high speeds.
Benefits of DKFL Solid Base:
Superior resistance to shock and shear loads, prevention of foot fatigue/failure, effective vibration dampening, and retention of geometric seat tolerances throughout the entire service life.
Metallurgy, Sealing, and Performance
- 100Cr6 Alloy Steel (AISI 52100): All internal bearing components are manufactured from high-carbon chromium alloy steel, heat-treated to 60-62 HRC, providing maximum resistance to surface wear, fatigue, and spalling.
- Dual Sealing System: Equipped with a nitrile rubber (NBR) contact seal and a rotating metal flinger shield. This creates centrifugal force that effectively repels abrasive dust and moisture from the raceway.
- Dense HT200 Cast Iron: The housing is cast with a fine-grain, high-density structure, ensuring excellent thermal resistance and vibration absorption under heavy industrial stress.
Core Industrial Applications
The 35mm bore size is a staple for medium-to-heavy torque transmission. DKFL UCP 207 is a critical component in:
- Conveyor Systems: Drive and idler drums in packaging, cement, and material handling lines.
- Agricultural Machinery: Power transmission shafts for harvesters, balers, and tillers.
- Industrial Fans & Blowers: Shaft support for high-flow ventilation and industrial exhaust systems.
- Processing & Crushing: Continuous operation in abrasive, high-dust environments like stone and recycling plants.
Critical Installation Protocols & Warnings
Step 1: Mount the bearing on a clean, burr-free shaft. Tighten base bolts loosely to the frame to allow self-alignment.
Step 2: Tighten housing base bolts to torque specifications uniformly.
Step 3 (Final): Tighten the two set screws on the inner ring alternately and evenly.
Critical Warning: Tightening set screws *before* securing the housing base induces axial pre-load, which can cause the bearing to overheat and seize prematurely.
Never use a steel hammer directly on the inner ring or seal shield. Impacts create micro-cracks in the hardened 100Cr6 steel and can deform the shield or fracture the cast housing. Always use a soft-face mallet or a proper sleeve tool.
- Shaft Tolerance: Recommended shaft tolerance for 35mm is h7 or js7. Foundation surface unevenness should not exceed 0.1mm to avoid stressing the housing feet.
- Lubrication Management: The unit is factory-lubricated. During periodic maintenance, inject only a small amount (1-2 pumps) of fresh grease. Over-greasing can push out the seal and cause temperature spikes.
