Bearings for Mining & Construction Equipment
TEDIN supplies mining equipment bearings and heavy-duty bearing solutions for crushers, vibrating screens, conveyors, excavators, loaders, drilling rigs and construction machinery operating under shock loads, dust, vibration and harsh working conditions.
Mining Equipment Bearings Built for Harsh-Duty Conditions
Mining equipment and construction machinery require bearings that can operate reliably under heavy loads, shock, vibration, dust, contamination and continuous-duty working environments.
Heavy Radial & Axial Loads
Bearings must support high load capacity in crushers, conveyors, gearboxes and heavy mobile equipment.
Shock & Impact Resistance
Crushers, loaders and drilling rigs often generate sudden impact loads that require strong bearing structures.
Vibration Stability
Vibrating screens and feeders need bearings designed for stable operation under continuous vibration.
Dust & Contamination Control
Proper bearing selection, sealing and lubrication help reduce wear in dusty and abrasive environments.
Misalignment Tolerance
Spherical roller bearings help compensate for shaft deflection and mounting misalignment in heavy-duty equipment.
Long Service Life
Reliable material, heat treatment and inspection help support bearing life in continuous operation.

Need help selecting bearings for harsh operating conditions?
Share your equipment type, load conditions, speed, operating temperature and environment. TEDIN can help recommend suitable mining and construction bearing solutions.
Bearing Selection Support for Real Working Conditions
Bearing selection for mining and construction equipment is not only about matching a part number. Load direction, vibration, dust, lubrication and installation space all affect bearing life.
TEDIN helps review the working position and operating conditions before recommending spherical roller bearings, cylindrical roller bearings, tapered roller bearings or thrust roller bearings.
What information helps us recommend the right bearing?
Equipment type, bearing position, existing model, shaft and housing size, load condition, speed, lubrication method and working environment.
Check the application position
We confirm where the bearing is used, such as crusher shafts, vibrating screen exciters, conveyor pulleys, gearboxes or wheel hubs.
- Equipment type and bearing location
- Original model or drawing reference
Match load direction and bearing type
We review whether the position requires radial load support, axial load support or combined load capacity.
- Radial, axial or combined loads
- Shock load and vibration level
Review clearance, sealing and lubrication
For dusty and high-vibration sites, clearance, lubrication and sealing arrangement are critical to bearing reliability.
- Clearance and cage requirements
- Grease, oil or external sealing conditions
Support replacement and custom needs
For maintenance projects, TEDIN can help check equivalent models and discuss non-standard sizes when required.
- Model cross reference support
- Standard and non-standard options
Typical Bearing Positions in Mining & Construction Equipment
Bearing choice depends heavily on where the bearing is installed. Crusher shafts, vibrating screen exciters and conveyor pulleys may work in the same plant, but their load, vibration and lubrication conditions are different.
| Equipment | Common Bearing Position | Working Conditions to Check | Common Bearing Types |
|---|---|---|---|
| Jaw crushers / cone crushers | Main shaft, eccentric shaft, transmission shaft | High radial load, impact load, dust contamination and intermittent shock during crushing. | |
| Vibrating screens | Exciter unit, screen shaft, vibrator assembly | Continuous vibration, high acceleration, heat build-up, clearance and cage requirements. | |
| Belt conveyors | Drive pulley, tail pulley, take-up pulley, gearbox input/output | Long running hours, dust, moisture, pulley misalignment and lubrication interval. | |
| Mining trucks / loaders | Wheel hub, axle, transmission and final drive positions | Combined radial and axial loads, low-speed heavy load and shock from road conditions. | |
| Drilling rigs | Rotary drive, feed mechanism, gearbox and thrust support | Axial load, vibration, site contamination and limited maintenance access. | |
| Industrial gearboxes | Input shaft, intermediate shaft, output shaft | Shaft speed, gear load direction, oil lubrication, operating temperature and housing fit. |
Replacing an existing bearing?
Send us the bearing model, equipment position, shaft size, housing size or photos of the old bearing. TEDIN can help check possible equivalent options before quotation.
From Bearing Model to Delivery
For replacement and project orders, TEDIN helps customers move from a bearing number, drawing or equipment position to a confirmed supply option with practical checks along the way.
Identify the Bearing
We start with the bearing model, old bearing photos, nameplate, drawing number or installation position.
Check Key Details
Dimensions, structure, clearance, cage type, sealing and load direction are reviewed when needed.
Confirm Supply Option
We check available TEDIN bearings or possible equivalent options for maintenance and project orders.
Pack and Ship
Bearings can be packed for export shipment with protection against moisture and handling damage.
What to Send When Asking for a Quote
A clear model number is helpful, but not always enough for heavy-duty equipment. These details can reduce back-and-forth communication.
- Bearing model or marking on the old bearing
- Inside diameter, outside diameter and width
- Equipment name and bearing position
- Required quantity and expected delivery time
- Photos, drawings or previous purchase records
If the model is unclear, send photos or dimensions first.
Send Bearing DetailsQuestions About Bearings in Mining & Construction Equipment
Bearings used in crushers, vibrating screens, conveyors, trucks and construction machinery work under heavy load, shock, dust and outdoor conditions. These questions focus on typical application issues rather than only bearing model selection.
Why do bearings fail early in mining and construction equipment?
Early failure is often related to dust contamination, shock load, poor lubrication, misalignment, water ingress or incorrect installation. In heavy-duty equipment, the bearing itself is only one part of the system; sealing, grease condition and mounting accuracy also affect service life.
Which bearing types are commonly used in crushers?
Crushers usually need bearings that can handle heavy radial load, impact and possible shaft deflection. Spherical roller bearings are widely used in crusher applications, while cylindrical roller bearings or tapered roller bearings may be used in certain shaft and gearbox positions.
What should be considered for vibrating screen bearings?
Vibrating screen bearings work with continuous vibration and high acceleration. Internal clearance, cage strength, lubrication, heat dissipation and fitting tolerance should be reviewed carefully. In many vibrating screen applications, spherical roller bearings are commonly used because they can accommodate heavy radial load and certain misalignment.
What bearings are used in conveyor pulleys and rollers?
Conveyor pulleys and rollers often use spherical roller bearings, deep groove ball bearings or other rolling bearings depending on load and size. For mining conveyors, attention should be paid to dust sealing, alignment, grease retention and long running hours.
How do dust, mud and water affect bearing service life?
Dust and mud can enter the bearing or housing and cause abrasive wear. Water may reduce grease performance and lead to corrosion. Once the lubrication film is damaged, rolling elements and raceways wear faster, which may result in noise, heat and unexpected shutdown.
How can bearing life be improved in heavy-duty equipment?
Bearing life can usually be improved by choosing the correct bearing type, using proper clearance, improving sealing, applying suitable lubrication, controlling installation accuracy and checking temperature or vibration during maintenance. A more expensive bearing alone may not solve problems caused by contamination or poor mounting.
