UC205 轴承尺寸与规格表

UC205 is one of the most widely used insert bearing sizes. It has a 25 mm bore (1 inch), which makes it a common choice for small to medium conveyor, agricultural and general industrial equipment.

The "UC" prefix means insert bearing, and "205" indicates the bore size group. In mounted bearing units the same insert is referred to as UCP205 (pillow block), UCF205 (square flange), UCFL205 (2-bolt flange) or UCT205 (take-up).

The table below lists the main UC205 dimensions. Always confirm critical dimensions against the equipment drawing or the old sample before ordering, because small differences in width or locking detail can affect fit.

• Bore (d): 25 mm / 1 inch
• Outer diameter (D): 52 mm
• Inner ring width (B): 34.1 mm
• Mass: about 0.22 kg per piece

The UC200 series covers light to medium duty shaft sizes. The chart below shows the standard CTZ range. Dimensions are nominal and should be verified against the product drawing for critical applications.

The UC300 series is the heavier duty counterpart of the UC200 series, with larger outer diameters and higher load capacity for the same bore. Use the chart below as a quick reference.

The UC205 insert is used inside several mounted bearing units. The bore stays the same, but the housing type changes the mounting method: UCP205 bolts to a base, UCF205 to a flat face, UCFL205 to a narrow side surface, and UCT205 slides for belt tension adjustment.

When replacing a failed unit, confirm whether you need the insert only or the complete mounted bearing unit. Send the model number, quantity and application to the manufacturer for confirmation.

Measure the shaft diameter first. Then check the outer diameter and width if the insert must fit an existing housing. Finally confirm the locking method and seal type with the equipment supplier.

If the old bearing number is unclear, a photo of the existing unit and the installation location helps the manufacturer confirm the correct product quickly.
