54770 Bearing for CSB105-17X 27.1 mm ID x 47 mm OD x 25.4 mm Bearing 86641856 for NEW HOLLAND BC5060 BC5070 570 baler

Product Advantage

The 86641856 Ball Bearing (27.1 mm Inner Diameter x 47 mm Outer Diameter x 25.4 mm Width) is a critical load-bearing component engineered for stable power transmission, uniform force distribution, and seamless compatibility with New Holland agricultural balers. Specifically designed for New Holland’s core baler models—including small square balers (BC5060, BC5070 series) and square balers (570 series)—it integrates with key operational assemblies such as baler plungers, drive shafts, and roller mechanisms. It ensures smooth rotational movement and balanced load handling during high-intensity baling operations, reduces mechanical friction and vibration, and prevents misalignment of rotating parts. This reliability minimizes unexpected downtime in harsh agricultural environments, from dusty hayfields to extended harvest hours and extreme temperature fluctuations.

Design

 The 86641856 Ball Bearing is precision-manufactured to meet exact New Holland OEM specifications, ensuring flawless integration with the original equipment’s adjacent components and mounting structures. The bearing features a 27.1 mm inner diameter, 47 mm outer diameter, and 25.4 mm width optimized for snug fitting with matching shafts and housings, while its deep groove ball design efficiently handles combined radial and axial loads. Constructed with high-strength GCr15 (AISI52100) bearing steel, it delivers superior load-carrying capacity and reduced friction, with a precision-machined raceway surface that enhances rotational smoothness. The component’s sealed structural design prevents the ingress of dirt, moisture, and field debris, forming a complete bearing system that resists impact and disperses operational stress. Its tailored profile fits seamlessly into baler assemblies without interfering with surrounding parts (e.g., baler chambers, drive gears, attachment points), ensuring unobstructed machinery performance and easy maintenance.

Dimensions

Manufactured to strict New Holland factory standards, the 86641856 Ball Bearing (27.1 mm ID x 47 mm OD x 25.4 mm W) enables direct replacement without modifying the equipment’s original structures or mounting points. Key dimensions—including the 27.1 mm inner diameter, 47 mm outer diameter, 25.4 mm width, and chamfer dimensions—are precision-machined to tight tolerances. This ensures perfect alignment with shafts, component housings, and adjacent parts, eliminating gaps that could cause vibration or uneven wear. The inner and outer race surfaces feature a smooth, precision-finished texture for uniform force distribution and easy installation, guaranteeing consistent performance across every operational cycle.

Performance & Durability

Crafted from high-quality OEM-grade GCr15 (AISI52100) bearing steel compliant with New Holland’s material standards, the ball bearing delivers exceptional durability and performance under demanding baling conditions. Its deep groove design and wear-resistant raceway ensure smooth rotation even under heavy loads and high speeds, while the robust steel construction resists deformation and fatigue. It maintains structural integrity and rotational precision across a wide temperature range (-20°C to 110°C), adapting to extreme weather from cold winters to hot harvest seasons. The component’s sealed design and corrosion-resistant surface treatment prevent degradation from hydraulic fluids, lubricants, and field debris, extending service life and reducing the need for frequent replacements. It withstands repeated mechanical stress from continuous baling operations, ensuring reliable performance in high-volume hay processing and rough field environments.

Excellent Cost-Effectiveness

As a direct factory supplier, we offer the 86641856 Ball Bearing at OEM-quality standards with more competitive pricing than original New Holland components. Every unit undergoes rigorous quality inspections—including dimensional accuracy checks, load-bearing capacity testing, wear resistance verification, and compatibility validation—ensuring no compromise on performance or reliability. This component provides a cost-efficient alternative to expensive OEM parts, helping farmers and equipment operators lower maintenance costs while safeguarding the functionality of critical baler systems. Its long service life, sealed design (reducing lubrication needs), and consistent performance further reduce total ownership costs by minimizing replacement frequency and downtime.

Large Inventory & Fast Delivery

We maintain a substantial inventory of the 86641856 Ball Bearing, covering all compatible New Holland baler models (BC5060, BC5070, 570 series), to ensure fast order fulfillment—even during peak agricultural seasons (e.g., hay baling, autumn harvest). We also provide professional technical support, including model-specific installation guidance (e.g., proper fitting procedures, lubrication recommendations), inspection methods, and maintenance tips tailored to baler plunger and drive system applications. Backed by a reliable after-sales guarantee (e.g., free replacement for quality-related defects within 12 months), we ensure a hassle-free procurement experience. This timely availability and support minimize equipment downtime caused by delayed replacement of this critical load-bearing component.
