SBLF200 & SALF200 Series 2-Bolt Flange Bearing Units — Light Duty, Compact Oval Housing
The SBLF200 and SALF200 series provide a light duty two-bolt oval flange in a compact housing that is significantly smaller and lighter than the equivalent UCFL200 for the same bore size. Where the UCFL200 is the standard oval flange for light to medium duty applications, the SBLF/SALF200 targets installations where the machine frame is sized to accommodate a smaller bearing housing footprint — light agricultural equipment, tabletop packaging machinery, small conveyor systems, and compact ventilation units. SBLF200 uses a setscrew insert (SB series) for bidirectional drives; SALF200 uses an eccentric collar insert (SA series) for unidirectional drives where the self-tightening collar provides more reliable retention.
Key Features
▼
Compact Lightweight Oval Housing
Significantly smaller and lighter than equivalent UCFL200 bore sizes. SBLF201 (12 mm bore) weighs only 0.27 kg. Smaller housing footprint suits compact machine frames.
🔧
SBLF200 = Setscrew / SALF200 = Eccentric Collar
Identical housing, two locking options. SBLF for bidirectional. SALF for unidirectional self-tightening. Upgrade by replacing insert only — housing unchanged.
⚙
Cast Iron Housing
Grey cast iron construction. Same corrosion resistance and surface hardness as full-duty oval flanges despite the lighter duty designation.
↔
Self-Aligning Insert
SB/SA insert bearing with spherical OD, 2° misalignment compensation, and axial float capacity.
📏
Full Metric and Inch Bore
12–40 mm metric bore with inch bore variants per housing size.
💧
Grease Fitting Standard
Factory pre-lubricated insert. Re-lubrication accessible in standard mounting orientations.
