Our goal:Our bearings, Your solutions!
professional manufacturer and distributor for special materials bearings
Engineered for continuous furnace, kiln, heat-treatment, and industrial oven systems where standard bearings fail due to lubrication breakdown and thermal expansion mismatch.
HTB series are our engineered high-temperature bearing codes. Please always use our part number when ordering.

Lubrication breakdown at continuous high temperature
Thermal expansion causing clearance collapse
Oxidation inside furnace environments
Incorrect replacement selection during procurement
Procurement Insight: Most premature failures are caused by lubrication collapse and improper clearance selection — not material defects. Standard bearings fail in weeks; our engineered series lasts 12–18 months.
| Factor | Standard Bearings | Our 500°C Bearings |
|---|---|---|
| Replacement frequency | Every 2–4 weeks | Every 12–18 months |
| Maintenance effort | Frequent relubrication | Reduced (solid lubrication) |
| Unplanned downtime risk | High | Controlled |
| Estimated annual downtime cost* | $48,000+ | $0 unplanned interruptions |
Example calculation based on typical furnace line assumptions. Actual savings depend on your operating conditions. Contact us for a personalized estimate.
*Based on 1 shutdown every 3 weeks, 4-hour downtime, $700/hour lost production + $500 labor/parts. Actual savings vary.
| Operating Temperature | Recommended Series |
|---|---|
| ≤300°C | Standard high-temp bearings |
| 300–450°C | Reinforced clearance series (C4 / custom) |
| 450–500°C | 500°C high temperature bearings (recommended) |

| Question | Answer |
|---|---|
| Do you offer warranty? | Yes — 18 months or 8,000 operating hours. Covers manufacturing defects. |
| What if bearings fail due to a defect? | Replacement or credit after verification; free failure analysis included for 3 samples. |
| Can we test samples before bulk order? | Absolutely. Sample orders with flexible quantity (2 pcs min) are welcome. |
| Expedited lead time for samples? | 10–12 days expedited service for first-time buyers (up to 20 pieces). |
| Is batch traceability provided? | Yes — batch number, heat treatment code, and clearance report on every package. |
| Can you replace a non-listed SKF/FAG model? | Yes — send us your model/drawing, we reply with cross-reference within 24h. |
