DIN 5417 Snap Rings for Bearings with Ring Groove
DIN 5417 snap rings retaining bearings with ring groove, bores 30 to 400: ring diameters d2 min/max, section g/s, groove and abutment dimensions — 2011 and 1976 editions.
Last updated: 2026-11
Specifications
DIN 5417 is the snap ring that retains a bearing whose outer ring carries a snap-ring groove — the external retaining ring that snaps into the housing bore and shoulders the bearing, deleting the housing shoulder that machining a plain bore would need. The collected 06/2011-edition table runs bores d1 30 to 400 with the free-state and installed ring diameters d2 min/max (383/386 at the 400 end), section g, ring thickness s (4.5 at 400) and the housing bore limit d4 max (414 at 400); the superseded 12/1976 edition is transcribed as a second table carrying the groove-side details (b, d3, d4, m) alongside the common dimensions — both verbatim. The ring orders as part of a system: ring + grooved bearing outer ring + housing tolerance (d4) — the bore limit column is the housing shop's acceptance dimension, which is why it sits in the ring standard.
| Standard / scope | DIN 5417 snap rings for bearings with ring groove — bores d1 30 to 400, edition 06/2011; superseded 12/1976 edition transcribed as a separate table |
|---|---|
| Ring diameters | d2 min/max per size (383/386 at d1 400) — free vs installed state against the housing bore |
| Section / thickness | g and s per size (s 4.5 at the 400 end) — the snap section that must open to bore diameter without set |
| Housing / groove data | d4 max housing bore limit (414 at 400); the 1976-edition table carries the groove-side columns b, d3, d4, m verbatim |
| Not tabulated | Material/spring grade, plier size, finish — per RFQ |
Materials
- Snap rings order in spring steel (hardened and tempered for snap set), phosphate or zinc finishes; stainless for corrosive housings at reduced snap life. Order by bearing bore designation with the housing bore tolerance stated — the ring, the bearing groove and the d4 bore limit are one fit system, and re-machining the housing without re-checking d4 is the usual failure path
Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (DIN 5417 Snap Rings for Bearings with Ring Groove) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantity is 10,000 pieces. Stock items run 3–7 days. Quantities or variants outside the standard range are confirmed at quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
What does the d4 max column govern — and who uses it?
It is the largest housing bore the ring system accepts: the ring is sized to seat at its installed diameter d2 against a bore within tolerance, and d4 max (414 at the 400 end) is the point past which the ring no longer develops enough hoop contact to shoulder the bearing — or falls out. The column belongs to the housing shop: it is the acceptance check after boring, the same way a shaft diameter is checked before fitting a bearing. In practice the failures come from two directions — bores machined oversize past d4 (ring loose, bearing walks) and bores left rough or chamfered oversize at the ring seat (ring snaps into a bigger effective diameter). Check the bored housing against d4 max before snapping the ring, and keep the ring seat face square.
Why are there two edition tables with different column sets?
The source page prints the current 06/2011 edition and the superseded 12/1976 edition as separate tables, and they organize the data differently: the current table carries the ring's own dimensions (d2 min/max, g, s, d4 max, mass), while the 1976 table also prints the groove-side columns (b, d3, d4, m) that legacy drawings reference. Both are transcribed verbatim — nothing merged — because a maintenance shop auditing a 1980s housing drawing will find its groove dimensions in the old table and its ring dimensions in the new one. For new design, use the 2011 edition and the bearing maker's groove data; for replacement against legacy drawings, read the 1976 table and order the ring by the same d1 designation.
