NUKR Product review

NUKR represents our commitment to precision engineering and industrial excellence. This product line delivers reliable performance and durable construction for demanding manufacturing applications.

NUKR and NUKRE series are bolt - mounted track rollers, which are pre - assembled bearing units. NUKR is based on double - row full - complement cylindrical roller bearings with two integral outer ring ribs. NUKRE is an upgraded version of NUKR, featuring an eccentric sleeve pressed onto the core column for easy adjustment of the outer ring's radial position. Both are ideal for heavy - duty, low - to - medium - speed linear or curved motion applications.

Key Features

Robust construction for industrial environments
Precision engineering for consistent performance
Designed for demanding manufacturing applications
Reliable operation with minimal maintenance
1. Robust Load - Carrying Capacity: Double - row full - complement cylindrical rollers enable these bearings to withstand heavy radial loads. They can also handle moderate shock and vibration loads, making them suitable for harsh industrial environments.
2. Integral Rib Design: The outer ring is equipped with two integral ribs, which effectively guide the rollers and prevent axial displacement, thus ensuring stable operation even under dynamic loads.
3. Efficient Adjustment (NUKRE Exclusive): The eccentric sleeve on the core column of NUKRE series allows for fine - tuning of the outer ring's radial position. This simplifies installation alignment and compensates for minor dimensional deviations in the mounting structure.
4. Ready - to - Install Unit: These are fully integrated units consisting of a precision - machined bolt, thrust washers, full - complement cylindrical rollers, and an outer ring. They can be directly mounted with bolts, which reduces assembly time and labor costs.
5. Durable Material & Construction: High - carbon chromium bearing steel (e.g., GCr15) is used for key components, ensuring excellent wear resistance and fatigue life. Optional seals (such as 2RS) are available to prevent contamination and retain lubricant.
6. Versatile Lubrication Options: Compatible with standard lubricating greases and oils. The design allows for re - lubrication, which extends the service life in continuous - operation scenarios.

Applications

The NUKR product series is engineered for various industrial sectors including manufacturing, automation, and precision machining applications where reliability and performance are critical.

NUKR/NUKRE series track rollers are widely used in various mechanical systems that require linear or curved motion with heavy loads. Typical applications include:

Material Handling Equipment: Chain conveyors, roller conveyors, and lifting platforms, where they support heavy loads during transportation.
Automotive Manufacturing: Welding lines, stamping machines, and assembly lines, coping with the heavy - duty and repetitive motion requirements.
Packaging Machinery: Cam mechanisms, slat conveyors, and film - wrapping machines, ensuring precise and stable motion control.
Construction Machinery: Concrete mixers, crane booms, and excavator track systems, enduring harsh working conditions and heavy loads.
Textile & Printing Equipment: Textile machine guide rails and printing press rollers, providing reliable support for high - precision motion.
Agricultural Machinery: Harvester cutting platforms and tractor linkage mechanisms, adapting to the variable load and vibration - prone working environment.

FAQ

1. What are the main differences between NUKR and NUKRE series?

NUKR is a standard double - row full - complement cylindrical roller track roller with two integral outer ring ribs. NUKRE adds an eccentric sleeve on the core column, which is used for radial position adjustment during installation to compensate for mounting errors. If installation alignment is critical, NUKRE is the better choice.

2. What is the maximum operating speed of these track rollers?

These are heavy - duty, low - to - medium - speed bearings. Generally, the maximum rotational speed is 1500–3000 rpm, but it is recommended to consult the manufacturer's catalog for specific models. Exceeding the speed limit may cause overheating and shorten the bearing life.

3. How to select between NUKR/NUKRE and other track roller series (e.g., KR, PWKR)?

Choose NUKR/NUKRE for heavy radial loads and the need for axial guidance from outer ring ribs.
KR series is suitable for light - to - medium loads with needle rollers and cage assemblies.
PWKR series has three outer ring ribs for applications requiring higher axial load capacity.

4. What lubrication method is recommended?

Pre - lubricate with lithium - based grease before installation. For continuous operation, re - lubricate regularly based on the operating conditions (temperature, load, and speed). For high - contamination environments, select sealed versions (e.g., 2RS) to prevent dust and moisture from entering.

5. How to achieve precise adjustment with NUKRE's eccentric sleeve?

Loosen the lock nut.
Rotate the eccentric sleeve using a wrench to adjust the outer ring's radial position (the adjustment range is usually ±0.5–1 mm, depending on the model).
Tighten the lock nut to the specified torque after adjustment to ensure the position is fixed.

6. What factors affect the service life?

Key factors include: proper lubrication, correct installation alignment, load within the rated range, operating temperature (ideally - 20°C to +120°C), and effective sealing against contamination. Improper use of any of these factors will significantly reduce the service life.
