NSK Japan 51106 Thrust Ball Bearing 30x47x11mm Single Row

Description

Product Overview

The NSK 51106 thrust ball bearing is a precision‑engineered component designed to meet the rigorous demands of modern industrial equipment. Measuring 30 mm in inner diameter, 47 mm in outer diameter, and 11 mm in width, this single‑row bearing provides a compact footprint while delivering exceptional axial load capacity. Crafted from high‑strength steel, the bearing incorporates hardened steel balls that resist deformation and wear, ensuring consistent performance over extended service intervals. The bearing’s sealed design protects internal elements from contaminants such as dust, moisture, and debris, extending its operational life and reducing the need for frequent maintenance.

NSK, a globally recognized leader in bearing technology, applies its extensive research and development expertise to the 51106 model, integrating advanced heat‑treatment processes and precision grinding techniques. These manufacturing methods result in a smooth running surface that minimizes friction, reduces heat generation, and improves energy efficiency in the host machinery. The bearing’s dimensional tolerances adhere to ISO standards, guaranteeing interchangeability with OEM specifications and facilitating straightforward retrofits or upgrades.

Key specifications include a load rating of 1 800 N, a maximum operating speed of 12 000 rpm, and a temperature range from –30 °C to +120 °C. The bearing’s design also incorporates a low‑noise profile, making it suitable for applications where acoustic performance is critical, such as in HVAC systems or precision manufacturing equipment. The 51106’s robust construction, combined with its compact dimensions, makes it an ideal solution for space‑constrained installations where reliability cannot be compromised.

Usage

This thrust ball bearing excels in a wide variety of industrial settings. It is commonly employed in gearboxes, where it absorbs axial forces generated by gear meshing, ensuring smooth power transmission and protecting shafts from premature wear. In pump assemblies, the bearing supports rotating shafts that experience fluctuating axial loads due to pressure changes, delivering stable operation and reducing the risk of cavitation. Conveyor systems benefit from the 51106’s ability to handle intermittent axial loads caused by load variations, maintaining consistent belt tension and preventing slippage.

Beyond traditional machinery, the bearing is suitable for robotics, CNC machines, and automated assembly lines where precise motion control and high reliability are paramount. Its compact size allows integration into tight mechanical envelopes, while its high load capacity ensures that even demanding tasks, such as rapid acceleration and deceleration cycles, are managed without compromising performance. The bearing’s resistance to corrosion and temperature extremes also makes it a viable choice for outdoor equipment, agricultural machinery, and marine applications where exposure to harsh environments is routine.

Installation of the NSK 51106 is straightforward for trained technicians. The bearing can be mounted using standard press tools, and its sealed design eliminates the need for additional lubrication during the initial setup. For applications requiring periodic inspection, the bearing’s external markings provide clear identification, simplifying inventory management and ensuring that the correct part is selected for replacement or maintenance activities.
