UCF Series Square Flange Bearing Units
UCF series square flange bearing units are designed for stable four-bolt mounting and reliable shaft support.
UCF series square flange bearing units mount a UC insert in a four-bolt cast F-housing for rigid side-plate or fixed-surface installation where pillow blocks cannot fit. Covering shaft bores from 25 mm to 90 mm (UCF205–UCF328), they provide stable support on vertical or horizontal surfaces with standard bolt spacing and ISO 9001 quality assurance.

Frequently Asked Questions
UCF square flange vs UCFL 2-bolt flange, which to choose?
UCF uses a four-bolt square flange for high rigidity on vertical or horizontal plates, while UCFL uses a two-bolt oval flange for lighter duty and tighter spaces. Choose UCF when the shaft sees side load or torque, and UCFL when weight and space matter more. Both share UC insert bore sizes, so UCF205 and UCFL205 both use a 25 mm bore. CTZ lists both ranges with full dimensions for correct mounting selection.
What is the MOQ for UCF square flange units?
CTZ accepts trial and full-container orders for UCF square flange units. Wholesale MOQ for common sizes such as UCF205, UCF208 and UCF210 often starts at a few hundred pieces per model, with mixed-model pallets available. OEM and private label UCF orders set MOQ by box printing and packing. Provide the models and quantity to the Ningbo team to confirm MOQ and unit price for your market.
What are the bolt hole dimensions of UCF units?
UCF square flange units follow standard four-bolt dimensions: for example UCF205 uses an F205 housing with a 4-bolt square pattern, and the bolt circle grows with size up to UCF218. CTZ publishes the bore, bolt spacing and overall flange dimensions for every UCF model so buyers can match the unit to the machine plate. If your plate pattern differs, send the drawing and CTZ can advise the closest standard UCF size.
How are UCF units packed for export?
UCF square flange units are packed in neutral packing by default, with OEM brand packing, custom boxes, labels and export cartons on request. Units go into inner boxes, master cartons and pallets for sea freight, and anti-rust protection can be added. CTZ confirms artwork, carton count and pallet type before production so distributors receive UCF orders ready for local sale and shelf display.
What is the delivery time for UCF square flange orders?
UCF square flange orders typically ship 20 to 30 days after deposit, based on quantity, model mix and packing. Common sizes like UCF205 and UCF210 are often partly stocked for faster dispatch, while custom OEM packing or large volumes need more time. CTZ arranges mixed container loads from Ningbo and gives a production and shipment schedule so distributors can plan stock for equipment assembly and maintenance.
