# Plain / sintered bushings ISO 2795: bore, outside diameter, thin series and length options (1 to 60 mm) + STEP/STL sleeves > What are the ISO 2795 sintered bushing sizes: bore, outside diameter (normal and thin series) and standard lengths, for example 8 × 12 × 8 and 10 × 16 × 16? - Category: Hardware › Bearings, rails & motion - Kind: Standard part - Basis: ISO 2795:2014 Table 1 (iTeh preview) with ISO 2795:1986 fit tolerances; McMaster-Carr linked for CAD - Page: https://xemstudio.com/objects/sintered-bushings-iso-2795/ · JSON: https://xemstudio.com/api/geometry?object=sintered-bushings-iso-2795 · Plain text: https://xemstudio.com/objects/sintered-bushings-iso-2795/sheet.txt - License: dimension sheet CC BY 4.0 (Xem Studio); files CC BY 4.0 or their publisher's license - Use in every chat: add https://xemstudio.com/mcp as a connector (https://xemstudio.com/use-with-ai/) **Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. ## Notes - ISO 2795 is the dimension standard for plain cylindrical bushings (sleeve bearings) made from sintered metal (oilite-style bronze or iron, self-lubricating). d is the bore, D the outside diameter; the normal series has a thicker wall, the thin series is for tight spaces. Lengths are a short list of preferred values per size. - Numbers: ISO 2795:2014 Table 1 as published by iTeh (bores 1 to 60). Parenthesised thin-series values (28 → 34, 30 → 36) are the standard's second choice. The preferred-length options for the 20 mm bore: the standard's last value (30) is not for the thin series. The sample ISO 2795:1986 page gives the fit tolerances: housing H7, bore after fitting H7 (D < 50) or H8 (D > 50), length js13. - McMaster-Carr's sintered-bronze sleeve bearings are linked as the CAD source; its inch part numbers are not mixed with the ISO sizes. - Files: 10 sleeves at an example length taken from the standard's L options (4 × 8 × 6, 5 × 9 × 8, 6 × 10 × 10, 8 × 12 × 12, 10 × 16 × 16, 12 × 18 × 20, 15 × 21 × 25, 16 × 22 × 25, 20 × 26 × 25, 25 × 32 × 30). Nominal bore and OD before press-fit: the bore closes slightly when the bush is pressed in, which is why the standard gives the after-fit tolerance. Other lengths: use the table. - Left out: flanged bushes (ISO 2795's flanged table was not legible), igus iglidur sizes (maker-specific, not read), inch bushings, tolerances of the unfitted bush (not read). ## Mating features (exact size;

the bore after pressing in is H7 for D under 50 and H8 above; length js13 (ISO 2795:1986). **What lengths exist for a 10 mm bore bushing?** 8, 10 or 16 mm, OD 16 (thin series 14). **Is a 10 × 14 × 15 bushing an ISO 2795 size?** 10 × 14 is the thin-series size, but 15 is not one of the listed lengths (8, 10, 16). ## Fits with - [Linear shafts Ø3 to Ø25 mm (h6), 100 to 1000 mm long](https://xemstudio.com/objects/linear-shafts-h6/) - [HK needle roller bearings (drawn cup): HK0306 to HK2020 bore, outside diameter and width + STEP/STL envelopes](https://xemstudio.com/objects/needle-roller-bearings-hk-series/) - [Ball bearings, 683 to 6210 and flanged F6xx (ISO 15)](https://xemstudio.com/objects/ball-bearings-metric/) - [Pillow block KP08 envelope with a 608 pocket](https://xemstudio.com/objects/pillow-block-kp08/) - [Flanged linear bushings LMF, LMK, LMH (and long LUU): bore, OD, length, flange size, bolt circle, hole + counterbore, 6 to 60 mm + STEP/STL (8 to 20 mm)](https://xemstudio.com/objects/flanged-linear-bushings-lmf-lmk-lmh/) - [Clevis pins ISO 2341 B, Ø3 to Ø8](https://xemstudio.com/objects/clevis-pins/)
