T200/CX is a specialized designation for heat-resistant tapered roller bearings designed to operate in high-temperature environments up to 200°C. Here’s a clear breakdown of what that means and why it matters:

Features of High Temperature Tapered Roller Bearings 200°C (T200/CX)

Temperature capability:

- Max: up to 200°C
- Recommended continuous operation: normal 180°C

Material:

- Material: Made from chromium steel material

Surface treatment:

- Manganese phosphate coating (Mn₃(PO ₄) ₂ (according to EN ISO 9717)
  Improves corrosion resistance and performance at high temperatures (options depending on the actual application)

Lubrication:

- Special high-temperature grease (mineral oil-based)
  Maintains lubrication film and reduces friction at elevated temperatures

Load capability:

- Designed to handle combined radial and axial loads

(typical of tapered roller bearings)

Mounting configuration:

- Often installed in pairs to form a stable, sealed unit

Typical Specifications

Shaft diameter range: 20 mm to 100 mm
Internal clearance: Increased (to compensate for thermal expansion)
Standards: Compatible with ISO dimensions (interchangeable in many cases)

Applications

These bearings are commonly used in:

Industrial ovens / furnaces
Drying systems (food, agriculture, materials)
Steel & metallurgical equipment
Conveyors in high-heat zones
Hot processing machinery

Practical Engineering Notes

Lubrication is critical: grease breakdown is often the limiting factor, not steel.
Thermal expansion must be considered: hence, larger internal clearance.
Speed is usually reduced at high temperatures to extend life.
