SBFD200 & SAFD200 Series 2-Bolt Flange Bearing Units — FD Housing, Slot Opposite Side from Locking
The SBFD200 and SAFD200 series use the FD housing variant — a two-bolt oval flange where the mounting slot is positioned on the opposite side of the housing from the setscrew or eccentric collar. This is the mirror orientation to the SBFW/SAFW200 FW housing, and serves installations where the primary load direction acts away from the locking mechanism, making the opposite-side bolt the more load-critical fixing. As with all SB/SA light duty oval flange variants, the SBFD and SAFD use the same compact housing dimensions as SBLF/SALF200 for equivalent bore sizes — the FD designation refers only to the slot orientation, not to a different housing size or load rating.
Key Features
▭
FD Housing — Slot Opposite Side from Locking
Mounting slot on the opposite side from the setscrew/eccentric collar. Select when the primary load direction acts away from the locking mechanism.
🔧
SBFD200 = Setscrew / SAFD200 = Eccentric Collar
Identical FD housing, two locking options. Upgrade by replacing insert only. Housing, J, A dimensions match SBFW for equivalent bore sizes.
▼
Compact Light Duty Housing
Same dimensions as SBLF/SALF200 and SBFW/SAFW200 for equivalent bore sizes. Designation indicates slot orientation, not a different housing size.
↔
SB/SA Insert Bearing
SB series setscrew for SBFD. SA series eccentric collar for SAFD. Self-aligning spherical OD, 2° misalignment, axial float.
📏
Full Metric and Inch Bore
12–40 mm metric bore with inch bore variants per housing size.
✅
Cast Iron Housing
Grey cast iron despite light duty designation. Standard corrosion and surface hardness properties.

Applications
🌿
Light Agricultural FD Position Oval Flanges
Oval flange positions where the belt or chain tension acts away from the locking collar side and the FD slot orientation better engages the bolt on the loaded side of the housing.
📦
Compact Packaging FD Oval Flange Supports
Drive shaft oval flange supports in compact packaging machines where the FD slot orientation is specified in the original machine frame drawing for load path reasons.
⚙
Fan Frame FD Oval Flanges
Small fan shaft FD housing oval flange supports where the aerodynamic thrust load direction favours the opposite-side slot orientation.
🧱
Light Conveyor FD Bracket Positions
Small conveyor frame oval flange positions where the belt tension load direction favours the FD slot orientation for better bolt engagement under the actual load.
🔄
Replacement in FD-Specified Machines
Direct replacement for existing SBFD/SAFD housings in machines where the FD slot orientation is specified in the original engineering drawing and must be maintained.
⛏
SAFD Unidirectional Eccentric Collar Upgrade
Any SBFD installation experiencing setscrew loosening on a unidirectional drive — replace with SAFD eccentric collar insert. Housing and bolt positions unchanged.
