Treat load, motion, lubrication, fit and contamination control as one system
A bearing system in heavy equipment involves more than a standard part number. Mill trunnion bearing shells carry heavy loads at low speed; copper-alloy crusher bushings accommodate oscillation and sliding; rotor rolling bearings withstand high speeds and impact. Housings, seals and lubrication systems work together to maintain alignment, clearances and cleanliness.
Sliding bearings Bearing shells, eccentric bushings, head bushings, trunnion bushings and pin bushings
Rolling bearings Spherical, cylindrical and tapered roller bearings, thrust bearings and special bearings
Mounting system Housings, end covers, location features, seals, oil grooves and lubricant supply
متطلبات التحديد Model, load, speed or oscillation, fit, lubrication, temperature and contamination
System scope
Motion Continuous rotation, heavy loads at low speed, oscillation, impact or axial thrust
Fits and location Journal, housing bore, clearance, roundness, surface roughness and location features
Lubrication Oil or grease, viscosity, supply, oil grooves and holes, filtration, cooling and oil return
Supply identification OEM, complete model, assembly number, part number, material and inspection scope
Inside diameter, outside diameter and length are not enough
Sliding bearings need a stable lubricant film to transfer loads into the housing. Rolling bearings require appropriate clearance, fits, preload, lubrication and contamination control. An incorrect interface can cause overheating, vibration, scoring, pitting or damage to the shaft and housing bore.
Bearing seals are adjacent components with a separate function. See the seals category page. Bearing and bushing enquiries should also include seal, lubrication and housing information so that replacement addresses the cause of failure.
Sliding bearings and bushings
Supports for heavy loads at low speed, oscillation and eccentric motion
Material is only one variable. Fits, oil grooves, clearances and journal condition are equally important.
Mill trunnion bearing shells
Support slow rotation of the mill shell and maintain a lubricating oil film. Check the journal, bearing housing, alloy layer, oil wedge, jacking-oil system and temperature monitoring.
Cone crusher eccentric bushings
Provide sliding support between the eccentric assembly and the main shaft or crushing head. Check eccentricity, inside and outside diameters, taper, oil grooves and installation orientation.
Cone crusher countershaft bushings
Support the countershaft and maintain pinion mesh. Check front and rear positions, journals, housing bores, oil passages, clearances and gear loads.
Cone crusher socket liners
Support oscillation of the crushing head on a spherical seat and provide a replaceable friction surface. Check spherical geometry, contact, lubrication, support and head assembly version.
Impact apron pivot pin bushings
Provide the pivot for apron movement or release. Check the pin, bearing pressure, oscillation angle, impact, lubrication and housing bore deformation.
Sugarcane mill bearing shells
Carry heavy crushing-roll loads at low speed in a wet environment containing cane juice. Check roll journals, housings, oil or water lubrication, corrosion and contamination.
Tower and stirred mill bearing sleeves
Protect or restore the mating surface of the agitator shaft. Check shaft position, load, interference fit, coaxiality, lubrication and adjacent seals.
Rolling bearings and housings
Supports for rotors, roll shafts and vibrating equipment
Confirm the bearing designation together with the shaft, housing, clearance, seals, lubrication and installation method.
Jaw crusher spherical roller bearings
Support the eccentric shaft under impact and misalignment. Check designation suffixes, clearance, journals, housing bores, lubrication and the heating or drive-up method used for installation.
Impact crusher rotor bearing housings
Locate the bearings and transfer rotor loads to the frame. Check centre height, split faces, fits, end covers, oil passages, seals and frame reference surfaces.
HPGR roll shaft bearing units
Carry very high roll loads while accommodating adjustment. Check locating and non-locating ends, bearing arrangement, housing, seals, lubrication and hydraulic-side loads.
Spiral classifier bearing assemblies
Support the long spiral shaft while accommodating slurry, sand and shaft deflection. Check upper and lower ends, lubrication, seals, axial location and maintenance access.
Grinding roller trunnion bearings
Support rotation or oscillation of the grinding roller about its trunnion. Check the roller assembly, loads, temperature, lubrication, contamination and end seals.
Materials and mating surfaces
Match materials to the shaft, housing bore, lubrication and surface condition
No single copper alloy or bearing steel grade is specified as a universal solution for every machine.
Failure diagnosis
Investigate overheating, scoring, pitting and looseness across the system
Replacing a bearing without correcting fit, lubrication or contamination problems usually leaves the cause of repeated failure unresolved.
| Symptoms | الفحوصات ذات الأولوية | Associated Risks |
|---|---|---|
| Sliding bearing overheating | Clearance, oil film, viscosity, oil supply, journal, load, alignment and cooling | Scoring, seizure, melting or separation of the bearing alloy |
| Uneven bushing wear | Shaft-to-bore coaxiality, uneven loading, oscillation angle, support deformation and oil-groove orientation | Increased clearance and changes in gear or shaft position |
| Raceway pitting or spalling | Load, internal clearance, lubricant film, contamination, installation damage and electrical erosion | Vibration, overheating and rolling-element damage |
| Bearing creep on the shaft or in the housing | Fit tolerances, roundness, surface condition, load direction, locking and temperature differences | Journal or housing bore wear and loss of location |
| Housing cracks or deformation | Base stiffness, bolts, shims, impact, centre height and shaft alignment | Uneven load distribution and premature bearing failure |
| Discoloured grease or particles in grease | الموانع, grease replenishment quantity, purge passages, water, dust, temperature and mixed greases | Abrasive wear, lubrication failure and corrosion |

Technical references: Metso lists gyratory crusher spider bushings, bottom shell bushings and thrust bearings as key commonly used parts. Its cone crusher structural information distinguishes eccentric, upper and lower head, and countershaft bushing positions. SKF explains that lubrication reduces friction and wear, helps prevent rust and removes contaminants. Different self-lubricating composites require different lubrication practices.Metso Gyratory Parts · SKF Plain Bearing Lubrication
