UCFC214 Four Bolt Round Flange Bearing Unit 70mm Bore UC214 Set Screw Lock Cast

1. Product Overview

UCFC214 is standard four-hole round flange bearing assembly, combined with FC214 cast iron round flange housing and UC214 spherical outer insert bearing, matching standard 70mm diameter shaft. Model Code Explanation:

• UC: Insert deep groove ball bearing with spherical outer surface, widened extended inner ring equipped with double symmetric set screws for shaft locking
• FC: Round four-bolt cast iron flange housing, suitable for wall, equipment panel and vertical side mounting
• 214: Standard 200 series mounted bearing, applicable shaft bore size 70mm

The insert bearing adopts spherical outer ring matching the spherical inner bore of the housing, realizing self-aligning compensation for slight shaft installation deflection and parallel errors, avoiding local overload, abnormal heating and premature bearing wear caused by assembly misalignment. Two set screws evenly distributed on the widened inner ring provide uniform clamping force, firmly lock the bearing unit on the cylindrical shaft, effectively prevent inner ring circumferential slipping under frequent start-stop impact torque and forward/reverse rotation. Equipped with double lip contact rubber seal plus outer anti-dust flinger double-layer isolation structure, factory pre-filled high-temperature extreme pressure lithium grease; an independent R1/8 grease nipple is reserved on the housing for supplementary lubrication without disassembling the whole unit. The housing is made of high-strength HT200 grey cast iron with thickened wall reinforced structure, excellent anti-vibration and anti-impact performance, stable long-term continuous operation under dusty, humid and heavy-load industrial environments. Widely applied to medium and large belt conveyors, grain dryers, rice milling and feed processing lines, agricultural combine harvesters, ventilation fans, packaging production equipment and all rotary machinery requiring wall-mounted flange installation.

3. Core Advantages

1. Pre-assembled integrated unit, insert bearing and cast iron flange housing are precisely matched in advance, only four bolts are needed to fix on equipment wall or panel, greatly shortening on-site assembly and adjustment time.
2. Spherical outer self-aligning matching structure, automatically absorb shaft installation deflection error within ±3°, eliminate abnormal heating and rapid wear caused by assembly misalignment and shaft bending.
3. Double symmetric set screw locking structure on widened inner ring, uniform stress distribution, reliable anti-slip locking performance under heavy impact load, stable bidirectional torque transmission.
4. Round four-bolt thick-wall cast iron flange housing, uniform stress distribution during heavy-load operation, strong vibration and impact resistance, adapt to farm, mining and other severe vibration working conditions.
5. Double lip rubber contact seal + outer dust flinger dual isolation system, effectively block grain powder, coal dust, mud splash and water vapor from invading internal raceway, reduce abrasive wear and extend service life in polluted workshops.
6. Independent grease nipple reserved on flange side, convenient for regular supplementary lubrication without disassembly, supporting long-time non-stop continuous production of processing equipment.
7. Standard 200 series medium heavy load insert bearing, large dynamic and static load rating, can stably bear large radial load and bidirectional light axial combined load, wide applicable load range.
8. Multiple customizable options: Triple-lip reinforced dust seal upgrade, full stainless steel insert bearing variant, OEM laser marking on flange outer surface, neutral export anti-rust carton packaging, food-grade white grease filling for grain food processing equipment.
