UCFLX00 Series 2-Bolt Flange Bearing Units — Medium Duty, Setscrew Locking
The UCFLX00 series provides the medium-duty step-up from the standard UCFL200 in the oval two-bolt flange format, exactly mirroring the UCFX00 relationship to UCF200 in the square four-bolt format. The heavier housing cross-section and higher-rated UC insert bearing of the UCFLX00 address the two most common failure modes of a standard-duty oval flange under elevated load: housing tilt causing loss of bearing alignment, and insert bearing fatigue from loads that exceed the UCFL200 capacity. The UCFLX00 specification table also lists both metric and inch bolt sizes — the oval flange bolt holes accept either standard at the listed dimensions.
Key Features
⚙
Heavy-Section Oval Housing
Heavier cast iron oval housing cross-section delivers higher bending stiffness and moment resistance than UCFL200 at equivalent bore sizes.
🔧
Setscrew Locking
Same dual 120° setscrew geometry as UCFL200. No crew retraining when upgrading from standard to medium duty oval flange.
↔
Higher-Rated UC Insert
Heavier UC insert bearing with higher C and C0 ratings than UCFL200 equivalent at same bore size.
📏
Metric and Inch Bolt Sizes
Both metric (M14, M16) and inch (3/8, 1/2, 5/8) bolt sizes listed — same bolt hole accepts either standard.
▭
Solid Base Option
Hollow base standard. Solid base (SB) on request.

Applications
▶
Heavy Belt Drive Oval Flange Positions
Drive and tail shaft oval flange supports where belt tensions push a UCFL200 toward its rated capacity and housing tilt under belt pull is a concern.
⛏
Aggregate & Quarry Side-Frame Supports
Screen and crusher auxiliary shaft oval flange supports on vertical side-frame panels where impact loads demand medium-duty housing stiffness.
🌿
Agricultural Heavy Implement Oval Flanges
Combine harvester and large implement shaft oval flange supports where crop-load variability creates peak loads exceeding UCFL200 capacity.
⚙
Mixer & Agitator Oval Flange Supports
Paddle mixer and agitator shaft oval flange supports on vertical vessel end plates where cantilevered impeller weight generates sustained bending moments.
🔄
Upgrade from UCFL200
Direct medium-duty upgrade from UCFL200 when field service shows short bearing life. Same setscrew procedure, same bore suffixes.
🏛
Building Materials Frame Drives
Extrusion screw and press roller shaft oval flange supports on vertical press frames where high cyclic radial loads demand housing stiffness beyond standard UCFL200.

Frequently Asked Questions
UCFLX00 vs UCFL300?
UCFLX00 is medium duty (25–50 mm). UCFL300 is heavy duty (25–140 mm). Use UCFLX00 when UCFL200 is marginal but UCFL300 oversized.
Same insert as UCFL200?
No — heavier UC insert with higher load ratings.
Why both metric and inch bolt sizes?
Same oval flange bolt holes accept both standards at listed dimensions.
What is the MOQ?
Standard parts: quantity-based MOQ. Samples 1–5 pcs. Multi-model from USD 1,500. Retail 1–2 pcs not accepted.
