Flanged bushing sizes
A flanged bushing (flange bearing) is a sleeve with a collar at one end that locates it axially and takes light thrust. The three standard series Bushing MFG makes are listed here: ISO 4379 Type F machined bronze, JBM-10F steel-backed PTFE composite and JBM-090F / 092F wrapped bronze. Flanged bimetal, graphite bronze and hardened steel bushings are made to drawing.
A flanged bushing size adds two dimensions to bore × outside diameter × length: the flange diameter F and the flange thickness t. The length L is measured over the flange. The flange sits against the housing face, so the housing bore needs a chamfer that clears the fillet under the flange, and the flange face carries the axial load as an annulus between D and F.
- ISO 4379 Type F cast bronze: Ø6–200 mm, thin flange Series 1 (t 1–5 mm) and heavy flange Series 2 (t 3–15 mm)
- JBM-10F PTFE composite: Ø6–40 mm, flange t 1–2 mm, shaft f7 / housing H7
- JBM-090F / 092F wrapped bronze: Ø25–300 mm, flange Ø listed per size, housing H7 / shaft f7–f8
- Bimetal JBM-800F, graphite bronze JBM-650F, sintered JBM-700F and hardened steel JBM-STF: to drawing
- For real axial load calculate the flange as a thrust washer or add a separate washer
Flanged bronze bushings, ISO 4379 Type F (mm)
Machined cast bronze (JBM-600 series). Series 1 has a thin flange (t 1–5 mm), Series 2 a heavy flange (3–15 mm) on a larger outside diameter. Lengths L include the flange.

Ø6–40 mm shaft in the standard series. The flange locates the bushing and carries light thrust; for real axial load add a JBM-10WC thrust washer.
Flanged wrapped bronze bushings, JBM-090F / 092F (mm)
CuSn8 wrapped bronze, Ø25–300 mm. Housing H7, shaft f7–f8, bore H9 after fitting; length includes the flange.

The housing chamfer must clear the fillet radius under the flange (table below) or the flange deforms on pressing.
Which flanged series
Choose the material first, from the lubrication regime and the load: machined bronze for greased or oiled heavy pivots and any size or flange proportion, PTFE composite for dry running and small sizes in volume, wrapped bronze for greased volume production with a thin wall. Then read the size from that product's table. The flange in every series locates the bushing; only the ISO 4379 Series 2 heavy flange and machined flanges to drawing are meant to carry a significant thrust load.
When the axial load matters, calculate it as a thrust washer: axial force divided by the annular area between D and F, compared with the static load rating of the material. If the number is high, use a separate thrust washer in the same material, which can be replaced without disturbing the sleeve.
| Series | Material | Bore range | Flange thickness t | Thrust duty | Fixing |
|---|---|---|---|---|---|
| ISO 4379 Type F Series 1 | Cast bronze, JBM-600 | Ø6–200 mm | 1–5 mm | Light; location | Not usual |
| ISO 4379 Type F Series 2 | Cast bronze, JBM-600 | Ø6–200 mm | 3–15 mm | Thrust bearing | Drilled for screw or pin on request |
| JBM-10F | Steel-backed PTFE | Ø6–40 mm | 1–2 mm | Light | Notch or hole on request |
| JBM-090F / 092F | Wrapped CuSn8 | Ø25–300 mm | = wall, 1.5–2.5 mm | Light to moderate | Notch or hole on request |
| JBM-800F, 650F, 700F, STF | Bimetal, graphite bronze, sintered, steel | To drawing | To drawing | Per material | To drawing |
Housing and installation
Machine the housing bore H7 and chamfer its mouth to clear the fillet under the flange (1–2 mm at 45° for a 2.5 mm wall); a sharp housing edge deforms the flange on pressing. Press on the flange face with a flat plate over a mandrel that supports the bore, never on the flange rim alone, and check that the flange sits flat against the housing face: a flange standing off the face bends under thrust and cracks a wrapped bushing at the fillet.
Where the flange must not rotate under thrust, order it with a notch, a hole for a pin or a drilled flange for a screw; state the position on the drawing.
Ordering a flanged size
Write bore × outside diameter × length and add flange Ø × flange thickness, the series or material and the quantity, e.g. 40 × 44 × 55 × 40 JBM-090F. Sizes outside the tables, flanges at both ends, flanges with holes or notches and flanged bushings in bimetal, graphite bronze, sintered bronze or hardened steel are made to drawing; samples are free and there is no minimum order.
Frequently asked questions
What is the standard flanged bushing size range?
ISO 4379 Type F covers Ø6–200 mm in cast bronze, JBM-10F Ø6–40 mm in steel-backed PTFE and JBM-090F / 092F Ø25–300 mm in wrapped bronze. Other sizes and materials are made to drawing.
How much thrust can a flanged bushing take?
Divide the axial force by the annular area between the outside diameter and the flange diameter and compare it with the static load limit of the material (45 N/mm² for greased cast bronze, 120 N/mm² for wrapped CuSn8, 250 N/mm² for PTFE composite). Thin flanges are for location; for real axial load use a heavy-flange bronze bushing or a thrust washer.
Is the flange thickness included in the length?
Yes. In all three series the length L is measured over the flange, from the flange face to the opposite end of the sleeve.
Do you make flanged bimetal or steel bushings?
Yes, to drawing: JBM-800F bimetal, JBM-650F graphite bronze, JBM-700F sintered bronze and JBM-STF hardened steel. Send bore, outside diameter, length, flange diameter and thickness.
Quote a flanged size from the tables.
Use the “Quote” link on any row, or send bore × OD × length, flange Ø × thickness, material and quantity. Non-standard flanges are quoted from the drawing.
