NKE 61817 ZZ 85x110x13 mm Ball Bearing

Technical Specifications & Core Features

Robust Sealed Ball Bearing for Industrial Shafts

The NKE 61817 ZZ is a deep groove ball bearing with dimensions 85 mm (inner diameter) x 110 mm (outer diameter) x 13 mm (width), fitted with metal shields on both sides (ZZ variant). This sealed construction ensures internal lubrication remains intact while protecting internal components from dust, debris and contaminants. Designed to accommodate radial and moderate axial loads, this bearing offers reliable shaft support and smooth rotation — critical for industrial applications, engines, gear assemblies, and heavy-duty equipment.

Benefits and Typical Applications

High Reliability, Low Maintenance, Versatile Industrial Use

• Sealed, maintenance-friendly design — metal shields retain grease and block dust or metal particles, significantly reducing maintenance intervals and prolonging bearing life.

• Durable construction with long service life — precisely machined steel rings and hardened balls ensure stability under load, resistance to wear, vibrations, and dynamic stresses.

• Smooth rotation and stable operation — deep-groove geometry and quality internal components deliver low friction, consistent rotation speed, and minimal vibration — vital for motors, gearboxes, pumps, and rotating assemblies.

• Versatile industrial compatibility — ideal for gear drives, electric motors, conveyors, industrial machines, machine tools, housing units — especially where quality and reliability are critical.

• Ready-to-install bearing unit — standard size and sealed configuration facilitate immediate integration into shafts or bearing housings, beneficial for production, maintenance, and OEM use.reliability.

Detailed Product Description

The NKE 61817 ZZ 85x110x13 mm ball bearing stands out as a dependable, high-performance component for industrial and mechanical systems requiring stable rotation, load support, and minimal maintenance. Its sealed design ensures that lubricant remains sealed within the bearing, protecting internal components from dust, metal shavings, moisture and other contaminants commonly found in harsh industrial environments. This dramatically reduces wear and extends service life — making it a cost-effective choice for long-term operations.

Thanks to the deep groove ball bearing design, this unit efficiently handles radial loads and moderate axial forces, ensuring stable shaft rotation and performance in gearboxes, drives, motors or any rotating assembly. The precisely hardened raceways and balls guarantee consistent behavior under load, resistance against dynamic stresses, and long-term operational stability. Low friction and smooth rolling minimize energy losses — enhancing the overall efficiency of machinery and reducing operational costs.

The 85 mm inner diameter and 110 mm outer diameter make this bearing suitable for medium to large shafts, while the 13 mm width keeps it relatively compact and easy to integrate. The metal shield (ZZ) ensures protection and reliability even in dusty, abrasive, or contaminated environments, common in industrial plants, workshops, or heavy-duty equipment applications.

For manufacturers, maintenance teams or OEMs seeking a sealed, durable, ready-to-install ball bearing — NKE 61817 ZZ 85x110x13 mm offers a robust solution that guarantees long service life, stable performance, and minimal maintenance overhead. It delivers consistent quality required for conveyors, gearboxes, motors, pumps, industrial machines, and heavy-duty mechanical assemblies.
