Clevises, Mountings & Rod-end Bearings
Rod eyes, clevises, trunnion mounts and pin bosses, machined from forging, bar or plate as the drawing requires.
The part that carries the load into the machine
Mounting parts are where cylinder failures become machine failures. The bore tolerance, the bush seat interference and the weld preparation all have to be right, and none of them is visible once the cylinder is assembled.
We machine from forging where the drawing specifies it, and from bar or plate where it does not. If the drawing is silent on the starting form, tell us the load case and we will ask the question rather than choose the cheapest blank.
Specification
| FIELD | UNIT | ORISE VALUE |
|---|---|---|
| Maximum part envelope | mm | 1000 × 500 × 500 on the machining centre |
| Maximum part weight on the machine | kg | 1200 |
| Pin bore range | mm | 20 to 260 |
| Bore tolerance | ISO class | H8 standard · H7 to order |
| Bore roughness Ra | µm | 1.6 as bored · 0.8 where the drawing calls for it |
| Bush seat interference | mm | 0.02 to 0.08, set from the bush supplier’s seat data |
| Spherical bearing seats | — | Machined to bearing maker’s published seat data |
| Starting form | — | Forging, bar or plate as specified |
| Materials | — | Q345B / S355 · 45# · 40Cr · 42CrMo · forged and cast steels to drawing |
| Weld preparation | — | To the assembly drawing |
| NDT | — | Magnetic particle and ultrasonic inspection available in house |
Bush fitting. State whether bushes are supplied fitted or loose. If fitted, name the bush supplier and part number so we can hold the correct seat fit rather than assume a nominal interference.
What we need on the drawing
- Pin bore diameter, tolerance and surface finish
- Bush or spherical bearing part number, and the seat fit required
- Starting form if it is a design requirement rather than a preference
- Weld preparation geometry and the welding standard that applies
- Any NDT requirement and its acceptance criteria
- Load case if you want us to comment on manufacturability
