Wrapped bronze bushing sizes
Complete standard size tables for CuSn8 wrapped bronze bushings in both surface types, diamond pocket (JBM-090) and through hole (JBM-092): straight sleeves from Ø10 to Ø300 mm, flanged bushings from Ø25 to Ø300 mm, with the DIN 1494 / ISO 3547 fits, chamfers and flange fillets. Both surface types share the same dimensional range, so a size listed here is available in either.
A wrapped bronze bushing size is written bore × outside diameter × length, with the wall in 1.0, 1.5, 2.0 or 2.5 mm steps of the CuSn8 strip. The OD column is nominal: a 10 × 12 bushing is made with an outside diameter of 12 mm +0.065 / +0.030 and the interference is deliberate. The bore column is the finished bore after fitting; in the free state the split bushing measures larger.
- Straight sleeves Ø10–300 mm in 58 sizes, walls 1.0–2.5 mm, lengths 10–100 mm
- Flanged bushings Ø25–300 mm in 29 sizes; flange Ø listed per size
- Fits: housing H7, shaft f7–f8, bore H9 after fitting; length 0 / −0.40 mm
- Lead-in chamfers and flange fillets dimensioned by wall thickness
- Same sizes in JBM-090 (diamond pockets) and JBM-092 (through holes); non-standard sizes to drawing
Wrapped bronze sleeves, JBM-090 / JBM-092 (mm)
Standard straight bushings, DIN 1494 / ISO 3547 series. The bore is the finished bore after fitting in an H7 housing; the OD is nominal, the bushing is made oversize for the press fit. Both surface types (diamond pockets, through holes) share every size.

The housing chamfer must clear the fillet radius under the flange (table below) or the flange deforms on pressing.
Fitting tolerances, DIN 1494 / ISO 3547 (mm)
Housings are machined H7, shafts f7–f8, and the bushing bore reaches H9 after press fitting.
| Nominal Ø | Bushing OD before fitting | Housing bore H7 | Bore H9 after fitting | Shaft f7–f8 |
|---|---|---|---|---|
| 10–18 | +0.065 / +0.030 | +0.018 / 0 | +0.046 / 0 | −0.016 / −0.043 |
| 30–50 | +0.085 / +0.045 | +0.025 / 0 | +0.062 / 0 | −0.025 / −0.064 |
| 50–80 | +0.100 / +0.055 | +0.030 / 0 | +0.074 / 0 | −0.030 / −0.076 |

Upper / lower deviations. The interference between the oversize OD and the H7 housing is deliberate: machine the housing to H7 and the press fit takes care of itself.
Chamfers and flange fillet by wall thickness (mm)
Lead-in chamfers are dimensioned by wall thickness, not by bore.
| Wall S3 | Outer chamfer Co | Inner chamfer Ci | Angle β | Flange fillet r |
|---|---|---|---|---|
| 0.75 | 0.5 ± 0.3 | 0.25 ± 0.2 | 35° ± 5° | — |
| 1.00 | 0.6 ± 0.3 | 0.30 ± 0.2 | 35° ± 5° | 1 −0.5 |
| 1.50 | 0.7 ± 0.3 | 0.50 ± 0.3 | 35° ± 5° | 1 ± 0.5 |
| 2.00 | 1.2 ± 0.4 | 0.50 ± 0.3 | 35° ± 5° | 1.5 ± 0.5 |
| 2.50 | 1.8 ± 0.6 | 0.60 ± 0.3 | 45° ± 5° | 2 ± 0.5 |
Three points before you use the figures
The OD column is nominal, not actual. A bushing listed as 10 × 12 is manufactured with an outside diameter of 12 mm +0.065 / +0.030; machine the housing to 12 mm H7 and the press fit takes care of itself. The bore column is the finished bore after fitting: before the bushing is pressed in, the bore measures larger, so do not inspect an unfitted bushing against the bore column and conclude it is out of specification. Length tolerance is 0 / −0.40 mm across the range.
The fitting-tolerance table gives the DIN 1494 / ISO 3547 system behind the sizes: an H7 housing closes the oversize sleeve so that the bore reaches H9, and an f7–f8 shaft then runs with the clearance that results. The chamfer table gives the lead-in chamfers, which scale with wall thickness so that the pressing tool and the housing chamfer can be sized without a drawing of each part.
Diamond pockets or through holes
JBM-090 has closed diamond-shaped pockets rolled into the bore that hold grease applied at assembly and release it as the shaft moves; it is the general-purpose type for greased pivots. JBM-092 has through holes that connect the bore to the housing so that grease or oil fed from outside reaches the running surface; it is the type for relubricated joints and for oil-fed housings. Both are CuSn8 (110–150 HB): 120 N/mm² static, 40 N/mm² dynamic, 2 m/s lubricated, −100 to +200 °C.
Ordering a size
Quote bore × outside diameter × length from the table with the surface type (090 or 092) and the quantity; for a flanged bushing add the F. Sizes, lengths or flanges outside the tables, other chamfers, and bushings in other bronze strips are quoted from the drawing. The tables are a standard-dimension reference, not a stock list; the size and surface combination is confirmed at quotation.
Frequently asked questions
What sizes do wrapped bronze bushings come in?
The JBM-090 / 092 standard series covers Ø10–300 mm bore in 58 straight sizes and Ø25–300 mm in 29 flanged sizes, with 1.0–2.5 mm walls and lengths of 10–100 mm. Other sizes are made to drawing.
Why does the bushing bore measure larger than the table before fitting?
Because the bushing is a split sleeve made oversize for a press fit; the bore column is the finished bore after pressing into an H7 housing. Inspect the bore in a ring gauge or the housing, not loose.
What housing and shaft tolerances do wrapped bronze bushings need?
Housing H7, shaft f7 to f8; the bushing bore reaches H9 after fitting. The fitting-tolerance table gives the deviations for each diameter range.
Are JBM-090 and JBM-092 sizes the same?
Yes. The two surface types (diamond pockets, through holes) are rolled from the same CuSn8 strip in the same dimension series, so every size is available in either.
How large a chamfer does the housing need?
Enough to clear the outer chamfer of the bushing and, for a flanged bushing, the fillet under the flange: 1–2 mm at 45° for a 2.5 mm wall. The chamfer table lists the bushing chamfers by wall thickness.
