Product Description

The F-81837 is a high‑performance Full Complement Needle Roller Bearing designed without an inner ring, featuring compact dimensions of 15mm x 36mm x 24mm (Inner Diameter x Outer Diameter x Width). Manufactured from premium GCr15 chrome steel, this bearing is engineered with a cage‑free (full complement) design—maximizing the number of needle rollers to deliver exceptional radial load capacity within a minimal cross‑section. The absence of an inner ring allows the bearing to mount directly onto a hardened and ground shaft, effectively using the shaft as the raceway. This configuration reduces assembly size, weight, and component count while improving shaft rigidity and concentricity.

Specifically optimized for printing press machinery, this open‑type bearing provides smooth, low‑friction rotation, high wear resistance, and reliable performance under continuous operation. Available in P0, P6, and P5 precision grades, it ensures stable accuracy, low vibration, and extended service life—making it an ideal choice for demanding printing and converting equipment.

Technical Specifications

Key Features & Advantages

• Full Complement Design (No Cage) – Incorporates the maximum possible number of needle rollers, significantly increasing radial load capacity compared to caged bearings of the same size.

• No Inner Ring – Mounts directly onto a hardened shaft, reducing assembly complexity, saving space, and enhancing shaft rigidity and run‑out accuracy.

• Compact & Lightweight – The 15x36x24mm envelope delivers high load‑handling performance in a small footprint, ideal for space‑constrained printing press subassemblies.

• Premium Material – Manufactured from GCr15 chrome steel for excellent hardness, wear resistance, and fatigue life under continuous high‑speed operation.

• Precision Options – Choose from P0 (standard), P6, or P5 precision to match your specific speed, noise, and alignment requirements.

• Low Friction & Stable Rotation – The full complement rollers and precise geometry minimize internal friction, ensuring smooth, quiet operation even at high rotational speeds.

Applications

• Printing press machinery (primary application – rollers, cylinders, and feed systems)

• Converting and paper‑processing equipment

• Textile machinery and packaging machines

• General industrial gearboxes and power transmission units

• Any application requiring high radial load capacity with a compact, direct‑shaft‑mount bearing design
