Product Introduction: UJK Thrust Cylindrical Roller Bearing (Type 80000 Series)

The UJK Thrust Cylindrical Roller Bearing (designated under the 80000 series) is engineered to deliver exceptional unidirectional axial load capacity in demanding industrial applications. As part of the premium UJK series, it combines robust construction with precision manufacturing to support heavy thrust loads, high rigidity, and reliable performance in low-to-moderate speed environments.

Key Features & Benefits

1. Ultra-High Axial Load Capacity

   • Cylindrical rollers with optimized length/diameter ratios provide maximum axial load support.

   • Ideal for applications requiring extreme rigidity under heavy thrust forces.

2. UJK-Grade Precision

   • Precision-ground raceways and rollers minimize friction and distribute stress evenly.

   • Enhanced heat treatment extends service life under shock/vibration loads.

3. Robust Cage Design

   • Machined brass or pressed steel cages maintain roller alignment and stability.

   • Suitable for moderate speeds (typically ≤ 1,500 rpm).

4. Simple Installation & Maintenance

   • Separable components (shaft washer, housing washer, roller/cage assembly) enable easy mounting.

5. Application Versatility

   • Standard designs operate at temperatures from -30°C to +150°C (lubricant-dependent).

   • Optional coatings (e.g., anti-corrosion) available for harsh environments.

Model & Dimension Specifications (Typical)

Notes:

• d: Bore diameter of shaft washer

• D: Outer diameter of housing washer

• T: Total bearing height

• Load ratings based on ISO 281 standards; actual values vary by configuration.

Design Variations & Suffixes

Typical Applications

• Heavy-duty presses & stamping machines

• Vertical pumps and compressors

• Crane slewing rings and hooks

• Extruders and injection molding machines

• Wind turbine pitch control systems

• Hydraulic cylinders and gearboxes

Installation Notes

1. Shaft/Housing Requirements:

   • Shaft washer requires interference fit (tolerance: k5/m6).

   • Housing washer needs loose fit (tolerance: H7).

2. Lubrication:

   • Grease (e.g., ISO VG 220) or oil lubrication required.

   • Relubrication intervals depend on speed/load (consult manual).
