SBPFTD200 & SAPFTD200 Series 2-Bolt Flange Bearing Units — Light Duty, Ductile Iron, Carriage Bolt Holes
The SBPFTD200 and SAPFTD200 series are the two-bolt oval flange counterpart of the three-bolt SBFCT/SAFCT200 series: light duty ductile iron housings with square carriage bolt holes for one-sided installation. Where the SBFCT/SAFCT series uses a three-bolt bracket configuration, the SBPFTD/SAPFTD series uses the more compact two-bolt oval format for installations where three fixing points are not available or not required. The ductile iron housing provides better impact resistance than grey cast iron at the same weight, and the square carriage bolt holes eliminate the need for spanner access to the bolt head during installation — the square neck of the carriage bolt locks against rotation in the square hole when the nut is tightened from the access side.
Key Features
▧
Square Carriage Bolt Holes
Square hole profile grips carriage bolt neck, preventing rotation during one-sided nut tightening. Enables installation in restricted-access locations without separate tooling for the bolt head.
▽
Ductile Iron Housing
Better impact and vibration resistance than grey cast iron. Standard for light duty equipment where occasional impact loads or frame vibration are a concern.
🔧
SBPFTD = Setscrew / SAPFTD = Eccentric Collar
Identical PFTD ductile iron housing, two locking options. Upgrade by replacing insert only. SAPFTD for unidirectional self-tightening drives.
▼
Compact Two-Bolt Oval Format
Two-bolt oval configuration. More compact than the three-bolt SBFCT/SAFCT bracket for installations where two fixings are adequate.
📏
Metric and Inch Bolt Sizes
Both metric (M8, M10) and inch (5/16, 3/8) bolt sizes listed for the square carriage bolt holes.
✅
Cast Iron Housing Option
Cast iron housing available on request for applications requiring higher compressive strength at the mounting face.

Applications
🌿
Light Agricultural Equipment Oval Flanges
Compact implement frame oval flange bearing positions where square carriage bolt holes allow one-sided installation into thin frame rail sections and ductile iron provides impact resistance.
📦
Compact Packaging Machine Oval Flanges
Oval flange shaft supports in compact packaging machines where above-housing bolt head access is restricted and carriage bolt installation from below is the only practical option.
⚙
Small Fan Unit Oval Flange Positions
Small fan shaft oval flange supports where the ductile iron housing handles installation impact better than grey cast iron and carriage bolt holes simplify mounting on panel-backed structures.
🧱
Light Conveyor Oval Flange Supports
Small conveyor drive shaft oval flange positions where two fixing points are adequate and the carriage bolt holes allow installation from the accessible frame face only.
▣
Two-Bolt Alternative to Three-Bolt SBFCT/SAFCT
Installations where the SBFCT/SAFCT three-bolt bracket has one more fixing point than the machine frame provides, and the two-bolt SBPFTD/SAPFTD oval flange is the appropriate compact alternative.
