Roulement de bloc d'oreiller d'alésage UCF208 de 40 mm pour équipement industriel

Lors de l'alignement de l'arbre, espace de montage, et le temps de maintenance deviennent des problèmes, choisir le bon Pillow block bearing manufacturer can directly affect equipment reliability. The UCF208 provides a practical solution with a 40 mm alésage, cast iron housing, four-bolt flange mounting, and a pre-lubricated UC208 insert bearing. You can install the complete unit directly onto a flat mounting surface instead of separately fitting a bearing and housing.

For conveyor systems, machines agricoles, les fans, pompes, équipement d'emballage, and other rotating equipment, you need a bearing unit that handles radial loads while accommodating normal mounting misalignment. Shenzhen Xinchangsheng portant Co., LTD. (Roulement XCCZC) supplies bearing solutions for industrial customers and supports OEM requirements for different applications.

Why Choose a UCF208 Pillow Block Bearing?

The UCF208 combines a UC208 deep groove ball bearing insert with a rigid cast iron housing. This configuration gives you a complete mounted bearing unit that simplifies installation and routine maintenance.

The bearing uses chrome steel (GCr15) for the rings and balls, while double rubber seals protect the insert bearing from common contaminants. The housing also receives a surface treatment designed to improve corrosion resistance in regular industrial environments.

Key UCF208 Specifications

• Bearing model: UCF208
• Insert bearing: UC208
• Diamètre d'alésage: 40 mm / 1.5748 dans
• Housing material: Fonte
• Montage: Four-bolt flange
• Bolt holes: 4 × 16 mm
• Recommended bolt: M14
• Scellage: Doubles joints en caoutchouc (2RS)
• Insert bearing material: Acier chromé (GCr15)
• Approximate weight: 2.8–3.2 kg per unit
• Design: Self-aligning mounted bearing unit

The spherical outer surface of the insert bearing works with the housing to accommodate angular misalignment. According to the supplied product specification, the design can compensate for approximately ±2° to ±3° of angular misalignment, depending on installation conditions.

UCF208 Cast Iron Pillow Block Bearing vs. Standard Bearing

If you are comparing a standalone deep groove ball bearing with a mounted bearing unit, the main difference is installation and application flexibility. The UCF208 combines the bearing, housing, scellés, and mounting structure into one assembly.

Donc, if you need a 40mm bore pillow block bearing for equipment with a flat mounting surface, the UCF208 offers a straightforward configuration.

Applications of UCF208 Industrial Pillow Block Bearings

The UCF208 works well in applications where a shaft needs stable support and convenient mounting. Its four-bolt flange allows you to secure the bearing housing to a suitable machine plate or structure.

Les applications courantes incluent:

• Systèmes de convoyeurs: Support rotating shafts in material transport equipment.
• Machines agricoles: Suitable for rotating components exposed to dust and vibration.
• Industrial fans and blowers: Provide shaft support in rotating ventilation equipment.
• Pumps and compressors: Support shafts under continuous operating conditions.
• Machines d'emballage: Help simplify bearing replacement during scheduled maintenance.
• Matériel de manutention: Provide a practical mounted bearing solution for rotating shafts.
• Machines de transformation des aliments: Can be considered where the operating environment and housing material meet the equipment requirements.
• Textile and woodworking machinery: Suitable for general shaft-support applications.

You should always verify load, vitesse, température, shaft tolerance, lubrification, and environmental conditions before final selection.

How to Select a UCF208 Pillow Block Bearing

If you are sourcing from a Pillow block bearing manufacturer, follow these steps before placing an order:

1. Confirm the shaft diameter.
   The UCF208 uses a 40 mm alésage, so first confirm that your shaft matches the required bearing dimensions and fit.
2. Check the mounting structure.
   Measure the mounting plate and bolt-hole positions. The UCF208 uses four 16 mm mounting holes designed for M14 bolts.
3. Review operating conditions.
   Consider radial load, charge axiale, rotational speed, température, vibration, poussière, humidité, et exposition chimique.
4. Select the housing material.
   Cast iron suits many general industrial applications. For harsher environments, XCCZC states that alternative stainless steel or coated housing options can be provided.
5. Confirm customization requirements.
   If you need different dimensions, conditionnement, or OEM specifications, provide your drawings, application details, and required quantities to the manufacturer.
