SBPFL200 & SAPFL200 Stamped Steel 2-Bolt Flange Bearing Units
SBPFL200 and SAPFL200 take the stamped-steel concept off the base plate and put it onto a vertical or end face. The oval two-bolt flange is compact, light and easy to integrate into sheet-metal frames. SBPFL uses setscrew locking; SAPFL uses eccentric locking.
The source catalogue lists 12-40 mm shafts. This makes the family a practical option for light machinery where there is no need for the mass of a cast-iron flange housing. Selection should still begin with the machine face: bolt spacing, shaft centre position and available back-side clearance all matter.
For a wider housing comparison, browse the bearings range before finalising the mounting style.
Machines that benefit from a thin stamped flange
These are application patterns where the housing concept is commonly considered. Final suitability still depends on load, speed, alignment, environment and the machine designer’s requirements.
Light conveyor side plates
An oval flange supports roller or drive shafts directly from a frame wall.
Ventilation and fan panels
Two-bolt face mounting is useful where the shaft passes through sheet metal and space is limited.
Agricultural guards and small assemblies
The light housing reduces bulk on auxiliary drives and fabricated equipment.
Packaging and handling modules
Compact vertical mounting supports shafts in narrow machine stations without a pedestal base.

A light face-mounted alternative to cast flange units
Oval two-bolt flange
Two opposed mounting points create a compact footprint on vertical plates and end panels.
Setscrew or eccentric locking
SBPFL and SAPFL share the housing concept but differ at the shaft connection.
12-40 mm published size range
The series is focused on small and medium light-duty shafts.
Pressed-steel construction
Low housing mass makes it suitable for equipment where a cast flange would be unnecessarily bulky.
Keeping a light flange flat during installation
The goal is to keep the stamped flange flat rather than dish the plate around the bolts.
If the shaft and holes do not line up, fix the frame condition instead of bending the housing into place.
The correct installation step depends on the insert type.
Bent stamped steel can change shaft alignment even when the bearing itself still turns.
Two-bolt oval geometry: what to measure
Use the product drawing as the final dimensional authority. The points below are practical filters that help narrow the correct model before a full drawing comparison.
J and H/L dimensions control whether the oval flange will land on the existing holes.
Use SBPFL for the setscrew style and SAPFL when eccentric locking is specified.
Thin sheet should be stiff enough to hold the bearing square without flexing around the two bolts.
Back-side clearance can be limited in enclosed machines, so B/B1, S and d1 deserve attention.
SBPFL/SAPFL versus pillow and three-bolt stamped units
SBPFL/SAPFL is the two-bolt face-mounted stamped family. SBPP/SAPP mounts on a base as a pillow block. SAPF/SAPFT and SBPF/SBPFT provide three-bolt flange geometry and extend to larger published shaft sizes.
