Bearings for Steel & Metallurgical Industry
Steel Mill Bearing Sourcing Review
Steel mill bearing RFQs should confirm the equipment position, failed model, suffix, temperature, load, contamination, quantity, destination, and requested documents before quotation. Heat, scale, water, and continuous-duty schedules can change clearance, cage, lubrication, and inspection needs.
Typical Operating Conditions
- Temperature: 80–200°C (ambient to extreme)
- Load: Heavy combined radial and axial
- Speed: Low to moderate (50–1500 RPM)
- Contamination: Scale, dust, water, mill coolant
- Duty cycle: Continuous 24/7, 365 days/year
Recommended Bearing Solutions
Continuous Casting Lines
E1 Series Spherical Roller Bearings with C4 clearance and machined brass cage (CA). High-capacity SRB options can be reviewed against roll-support load requirements, while C4 clearance may be reviewed when heat and fit data are provided. Cage choice should be confirmed with temperature, speed, and lubrication.
For caster-specific RFQs, use the continuous casting bearing route to prepare position, temperature, water exposure, suffix, quantity, and downtime details.
Rolling Mill Stands
Cylindrical Roller Bearings (NU/NJ series) for backup roll positions where high radial rigidity and precision are critical. Standard Spherical Roller Bearings (23200, 24100 series) for work roll positions where self-alignment compensates for roll deflection.
Conveyor Systems
Sealed Spherical Roller Bearings (SB Series) for conveyor pulleys exposed to scale and dust. Seal type, grease, speed, and temperature should be reviewed before replacing open bearings in hard-to-access conveyor positions.
Performance Results
- Review clearance and cage with heat, water, and scale exposure
- Confirm model, suffix, and position before quotation
- Prepare inspection and document requirements before order review
- Use related steel routes when the request is for rolling mills or continuous casting

RFQ Details Buyers Should Send
Send the equipment type, bearing position, failed model, suffix, load condition, contamination level, lubrication method, quantity, destination, downtime target, and document needs for application-specific review.
| RFQ detail | Example | Why it matters |
|---|---|---|
| application equipment | crusher, vibrating screen, fan, gearbox, conveyor pulley, paper machine, or steel mill position | Application context affects load, shock, speed, contamination, lubrication, and document review. |
| bearing position | drive side, non-drive side, screen exciter, crusher pitman, fan shaft, gearbox input shaft | Bearing position helps review load direction, vibration exposure, access for lubrication, and failure risk. |
| failed model | Photo of old bearing marking, OEM manual reference, or removed bearing code | The failed model helps compare original specification, suffix, and possible replacement route. |
| full suffix / marking | K, K30, C3, C4, W33, CA, CC, MB, 2RS, or full ring marking photo | Suffixes can change bore type, clearance, cage design, lubrication groove, sealing, and replacement risk. |
| load condition | Heavy radial load, shock load, axial load, reversing load, or unknown with equipment details | Load condition affects series selection, cage preference, and whether high-capacity options should be reviewed. |
| environment | Dust, water, slurry, outdoor exposure, high humidity, cement dust, paper mill moisture | Environment affects sealing, grease, corrosion risk, packing, and maintenance interval review. |
| lubrication method | Grease gun, centralized lubrication, oil bath, oil circulation, W33 groove, or sealed bearing | Lubrication method affects suffix review, housing compatibility, contamination control, and relubrication planning. |
| quantity | 1 large bearing, 2 pcs for maintenance, 50 pcs distributor stock, or annual demand | Quantity affects quote route, packing, production planning, inspection scope, and freight review. |
| destination | Destination country, port, warehouse, distributor address, or project site region | Destination affects export documents, packing method, shipping route, and trade-term review. |
| target timing | Maintenance shutdown date, urgent repair, trial order timing, or normal replenishment schedule | Timing helps separate availability review, production planning, sample validation, and consolidated shipment options. |
| required documents | Inspection report, material certificate, COO, RoHS / REACH statement, packing photos, buyer template | Document requirements must be confirmed before quotation because scope depends on order route and buyer template. |
