ZCuSn10P1 Sleeve Bushings for Wire Straightener Adjustment Crossheads
Request a ZCuSn10P1 cast tin-bronze sleeve for the guide posts of a wire-straightening roller adjustment crosshead. These sleeves guide slow setting movement and resist the reaction transmitted by the roller carrier. They are not the roller spindle bearings and do not establish finished-wire straightness on their own.
Distinguish guide-post sliding from adjustment-screw drive
Give the guide-post spacing, bearing span and the offset between the roller reaction and the guide plane. A pair of short sleeves can bind if the crosshead tilts under load even when each sleeve fits a loose post. Show the separate adjustment screw, nut and locking mechanism so the quotation does not confuse a smooth bearing bore with a threaded drive nut.
ZCuSn10P1 is the requested cast copper-alloy designation. Confirm the applicable casting standard, material condition and lubricant; phosphorus-bearing tin bronze must not be silently replaced with QSn4-4-4 or an overseas grade. A plain smooth sleeve needs the agreed lubrication arrangement, while adding grooves would require a revised drawing and review of remaining bearing land.
Application boundaries to confirm
Use this enquiry for an existing plain-guide design. Replacing a preloaded rolling guide changes friction, stiffness and positioning behaviour and needs system approval. Steel wire scale, swarf and water-based lubricants must be considered at the guide surface rather than judged from general alloy descriptions.
Dimensions and drawing-based quotation checklist
| Review item | Information required |
|---|---|
| Guide layout | Post diameter, sleeve OD/length, guide spacing, span, travel and load offset. |
| Clearance and alignment | New post tolerances, installed bore target, coaxiality and acceptable crosshead tilt. |
| Service | Roller reaction, locking sequence, adjustment frequency, scale protection and lubricant. |
| Order | ZCuSn10P1 casting specification, dimensional drawing with revision, quantity and acceptance checks. |
Identify metric or inch units and distinguish worn sample measurements from intended new-part dimensions. Include the mating-part drawing and requested material or dimensional documents; their scope and availability are confirmed with the quotation.
Installation and selection checks
Inspect guide posts for scoring and measure both housing seats. Fit sleeves with support against the housing, check the installed bores, then verify parallel movement before attaching the roller load. Confirm that locking the adjustment does not distort the crosshead or pinch a guide sleeve.
Frequently asked questions
Is this the straightening roller bearing?
No. It is the slow-moving crosshead guide sleeve. A roller spindle is a separate position with a different speed and load assessment.
Can a smooth sleeve replace the adjustment nut?
No. The guide bore and the threaded drive perform different functions. Supply the crosshead assembly drawing.
What is most useful for a replacement quote?
Send both post and housing measurements, intended new clearances and the guide layout. A single worn bore diameter is insufficient.
Request a drawing-based replacement quotation
Send the drawing and duty to BONIU, identifying ZCuSn10P1 cast tin bronze, quantity and revision. Material route, fit, manufacturing feasibility and inspection scope are reviewed before the quotation is confirmed.
