FKU115 Heavy‑Duty V‑Groove Guide Roller Bearing (No Bolt Shaft)The FKU115 is a high‑performance heavy‑load linear guide roller bearing designed as a direct replacement for NADELLA FKU115. Featuring a double row tapered roller structure and no bolt shaft design, it delivers exceptional radial and axial load capacity for heavy‑duty linear motion systems.

Brand: CNXM / High‑quality Chinese replacement
Type: V‑groove guide roller bearing (no bolt shaft)

Core Advantages:

No Bolt Shaft Design: Installed directly on a dedicated shaft, offering flexible mounting and compatibility with custom shafts.

Superior Load Capacity: Double row tapered roller design withstands heavy radial, axial, and impact loads in high‑speed linear motion systems.

Precision Alignment: Convex V‑groove outer ring reduces edge stress and compensates for minor track misalignment.

Durability: Blackened outer ring and GCr15 steel ensure excellent corrosion resistance and long service life in harsh industrial environments.

Interchangeability: Fully interchangeable with NADELLA FKU115 and compatible with RKU115 series (eccentric vs. concentric bolt).

Typical ApplicationsIdeal for heavy‑duty linear motion systems including:
Gantry machining centers, heavy machine tools, and rolling mills
Automated production lines, heavy conveyors, and robotic walking mechanisms
Metallurgical, mining, port machinery, and precision industrial equipment
High‑precision linear guide systems requiring heavy load support

4.457 Eccentric Adjustable Bearing – Optimized for Heavy-Duty Industrial Applications

Upgrade your forklift with the 4.455 Composite Roller Bearing—eccentric adjustable design for precise installation error compensation. Heavy-duty combined structure ensures high rigidity and long service life.

4.455 Eccentric Adjustable Combined Roller Bearing for forklifts. Combined structure delivers low friction, heavy-load capacity and easy adjustment. Perfect for industrial material handling equipment.

4.455 Forklift Composite Roller Bearing with eccentric adjustable feature. Engineered for heavy axial loads, easy alignment and reduced maintenance. Compatible with most forklift models. Trust the 4.455 combined roller bearing for smooth, efficient material handling operations.

PU (Polyurethane) lubricated gears are high-performance transmission components integrating the toughness of PU with excellent lubricity. They boast outstanding wear resistance, reducing friction between gear teeth effectively, thus extending service life and lowering noise during operation.
With good elasticity and impact resistance, these gears adapt well to light and medium-load applications, avoiding rigid collisions. They are widely used in household appliances, office equipment, small machinery and automotive accessories due to their corrosion resistance and stable transmission efficiency. The integrated lubrication design simplifies maintenance, making them cost-effective and reliable choices for daily transmission systems.
