When machine space is limited, choosing the right Mounted ball bearings can directly affect installation, alignment, maintenance, and equipment reliability. The UCFL205 flanged bearing unit gives you a compact two-bolt mounting solution for a 25 mm shaft while combining a cast iron housing with a UC205 insert bearing. For conveyors, agricultural equipment, fans, packaging machinery, and material handling systems, you need a bearing unit that fits the available space without creating unnecessary installation complexity. XCCZC Bearing manufactures precision bearing products and supports OEM requirements for customers across more than 20 countries.
The UCFL205 is a two-bolt flanged bearing unit designed to support a 25 mm shaft. Its rhombus-shaped housing provides a practical alternative when a conventional four-bolt flange or UCP pillow block cannot fit the machine structure.
The unit comes pre-assembled with a UC205 insert bearing, double rubber seals, set-screw locking, and a grease fitting. This configuration allows you to mount the bearing directly onto the shaft and machine frame.

These dimensions make the UCFL205 suitable when you need compact mounted bearings with straightforward shaft installation. The 16 mm clearance holes can accommodate M14 or 5/8-inch mounting bolts, depending on your machine design.
The UCFL205 uses a two-bolt rhombus flange rather than a larger four-bolt housing. Therefore, you can install it on compact machine frames, conveyor structures, fan assemblies, and retrofit equipment where mounting space is restricted.
The UC205 insert uses a spherical outer surface that allows the bearing to accommodate minor mounting misalignment. This self-aligning bearing design can help reduce binding caused by small alignment deviations between the shaft and housing.
However, you should still maintain proper shaft alignment and mounting accuracy. Self-alignment does not replace correct installation practices.
The cast iron housing provides structural support for industrial applications, while the integrated grease fitting allows convenient relubrication. You can access the lubrication point without removing the complete bearing unit from the machine.
For equipment operating in dusty, humid, or continuous-duty environments, establish a lubrication schedule based on actual operating conditions rather than relying on a fixed interval.
Selecting the right bearing housing depends on available space, mounting method, shaft diameter, and load requirements.
| Bearing Type | Mounting | Typical Advantage | Suitable Use |
|---|---|---|---|
| UCFL205 | Two-bolt flange | Compact side mounting | Conveyors, fans, agricultural equipment |
| UCP Bearing | Two-bolt pillow block | Simple horizontal shaft support | Conveyor shafts, machinery frames |
| Four-bolt flange | Four-bolt flange | Larger mounting footprint | Heavier structural applications |
| Insert bearing | Shaft-mounted | Flexible housing selection | Custom machinery assemblies |
If your machine requires side mounting around a 25 mm shaft and has limited installation space, the UCFL205 provides a practical configuration.
Follow these basic steps when installing the unit:
This installation sequence helps you reduce unnecessary loading during startup and makes future maintenance easier.
You can use this flange ball bearing unit across various light- to medium-duty systems, including:
For example, a conveyor designer can use the UCFL205 where a side-mounted bearing is required but the machine frame cannot accommodate a conventional pillow block. Similarly, fan and blower assemblies can benefit from its compact two-bolt configuration.
Shenzhen Xinchangsheng Bearing Co., LTD., operating as XCCZC Bearing, was founded in 2002 and focuses on precision bearing manufacturing. The company operates a 5,000 m² modern factory with reported monthly output of approximately 3 million bearings.
Its manufacturing and engineering capabilities support both standard and customized bearing requirements. XCCZC Bearing reports more than 1,000 global OEM projects and serves customers in 20+ countries.
For quality control, the company states that it performs 100% inspection before shipment. It also provides OEM services covering bearing dimensions, logos, and packaging, while engineering and sales teams provide technical support for different application requirements.
1. What shaft size does a UCFL205 bearing support?
The UCFL205 is designed for a 25 mm shaft and uses a UC205 insert bearing.
2. Is UCFL205 a pillow block bearing?
UCFL205 belongs to the mounted bearing family but uses a two-bolt flanged housing. It differs from a UCP pillow block because the housing mounts through a flange rather than sitting beneath the shaft.
3. Can XCCZC Bearing provide customized mounted bearings?
Yes. XCCZC Bearing states that it provides OEM services for customized bearing sizes, logos, and packaging. You can discuss application requirements, dimensions, and production specifications with its engineering and sales teams.
The Mounted ball bearings UCFL205 provides a compact two-bolt mounting configuration, 25 mm shaft compatibility, cast iron housing, UC205 insert bearing, and self-aligning capability for a range of industrial applications. With 130 mm overall length, 99 mm bolt spacing, and a weight of approximately 0.59–0.65 kg, it offers a practical solution where installation space is limited. XCCZC Bearing combines bearing manufacturing experience, OEM support, 100% pre-shipment inspection, and a 5,000 m² production facility to support different industrial bearing requirements.
If you are sourcing UCFL205 mounted ball bearings for conveyors, fans, agricultural machinery, packaging equipment, or other industrial systems, contact XCCZC Bearing with your shaft diameter, load requirements, operating speed, mounting dimensions, and application environment. The engineering team can help you confirm the suitable bearing configuration and OEM requirements before production.
