The NTN UCP206D1 is a high-performance two-bolt pillow block mounted bearing unit from NTN's comprehensive range of standard mounted ball bearing solutions. This integrated assembly combines a UC206D1 wide inner ring ball bearing insert with set screw locking housed in a robust P206D1 cast iron one-piece pillow block housing.
The NTN UCP206D1 is a high-performance two-bolt pillow block mounted bearing unit from NTN's comprehensive range of standard mounted ball bearing solutions. This integrated assembly combines a UC206D1 wide inner ring ball bearing insert with set screw locking housed in a robust P206D1 cast iron one-piece pillow block housing. Engineered for quick installation and reliable operation, this unit provides secure shaft support for industrial applications requiring a stable, space-efficient mounting solution with two-point bolt fixation. It features NTN's proprietary ball-point set screws for reliable shaft locking even under vibration or impact loads.
Core Features
- Set Screw Locking Mechanism: Two set screws positioned 120° apart with NTN's unique ball-point design ensure secure attachment to shafts without additional locking devices, simplifying installation and maintenance while preventing fretting wear on shaft surfaces
- Self-Aligning Performance: Spherical outer ring of the bearing insert accommodates up to 2° of initial shaft misalignment, reducing stress concentrations and extending bearing service life
- Dual Protection System: Nitrile rubber contact seals with steel slingers effectively retain lubricant while preventing contamination from dust, dirt, and moisture ingress
- Single-Piece Cast Iron Housing: P206D1 housing provides exceptional structural rigidity, vibration damping, and durability for demanding industrial environments
- Relubricatable Design: Features a grease fitting for easy maintenance and extended operational life by allowing fresh lubricant to be added without disassembly
- Wide Temperature Range: Operates reliably from -40°C to 120°C (-40°F to 250°F), suitable for diverse industrial operating conditions
- Light Duty Performance: Optimized for applications with moderate loads and speeds, providing an excellent balance of performance and cost-effectiveness
