The Metso Nordberg C80 Jaw Crusher Tightening Bushing (Part No. ONA-908583) is a precision-machined bronze/brass sleeve used in the C80 crusher to clamp, center and secure a rotating or bearing-mounted component in its correct position. In operation the C80 is subject to constant vibration and impact; the tightening bushing locks the mating part on the shaft / housing so it won’t move, loosen or wear the bore prematurely. This part is supplied as a wear & spare item and is packed in sets/crates for fast replacement on site.
Machine: Metso / Nordberg C80 jaw crusher
Function area: tightening / locking area of the crusher assembly (for securing matched sleeves, bearings or pitman-related parts, according to the C80 layout)
Purpose: to keep the fitted part in line, stop axial movement, and maintain crusher running clearance
In short: if your C80 starts to show play, abnormal vibration or looseness around a bushed connection, this tightening bushing is the part that restores the correct fit.
Exact C80 specification – manufactured to the Metso/Nordberg C80 dimensions, part code ONA-908583, drop-in replacement.
High-strength bronze/brass material – good compressive strength and natural lubricity, ideal for clamping around steel components.
Anti-loosening tightening design – when tightened, it grips the mating part uniformly, preventing micro-movement that causes fretting or noise.
Corrosion-protected surface – yellow/gold finish for storage, sea freight and long-term stocking.
Stable crusher performance – by keeping the shaft/bearing/sleeve fixed, the crusher maintains its designed stroke and output.
Easy maintenance – cylindrical shape, accessible from outside, can be changed during a normal shutdown.
During overhaul of the C80 pitman / bearing / shaft area
When the existing bushing is worn, cracked, deformed or seized
When there is axial movement on a component that should be locked
When installing new aftermarket parts and you want OEM-size tightening hardware
Q1: Is this bushing universal for all Metso jaw crushers?
No. This model is made for the Nordberg C80. Other C-series crushers use different tightening bushings.
Q2: Can I reuse the old tightening bushing?
Not recommended. Once it has been tightened and worked under vibration, the contact surface can wear. Replacing it ensures proper clamping force.
Q3: What material is it?
High-quality bronze/brass (yellow metal) chosen for strength, wear resistance and good fit against steel parts.
Q4: Can it be supplied together with other C80 wear parts?
Yes – it’s often shipped together with C80 bearings, sleeves, toggle components and jaw wear parts to save freight.
Q5: What happens if I don’t replace a loose tightening bushing?
The secured part may move, which can lead to misalignment, extra vibration, faster bearing wear and unplanned downtime.
