Product Description

 

 

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.

Design Variations & Suffixes

Suffix	Feature	Application
C3	Increased internal clearance	Thermal expansion compensation
P5	High precision grade	Machine tools, precision equipment
2RS1	Rubber seals (both sides)	Contaminated environments (e.g., mining)
M	Machined brass cage	High-speed capability (>1,500 rpm)
W33	Lubrication groove + holes	Forced oil lubrication systems

 

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).
