146 Baler Knife Arm Roller 25.4mm OD x 12.7mm Roller baler for New Holland BC5060 BC5070 570 Baler

Product Advantage

The 146 - Baler Knife Arm Roller is a high-reliability agricultural component engineered for superior wear resistance, stable operation, and precise fitment within New Holland small square baler systems. Specifically designed for New Holland BC5060 and BC5070 balers, this knife arm roller is essential to smooth movement of the baler’s knife arm during hay/straw baling operations, ensuring consistent cutting performance, reducing baler jams, and maintaining efficient bale production in demanding field conditions.

Design

The knife arm roller is precisely engineered and assembled to meet exact New Holland OEM specifications, ensuring seamless integration with the baler’s knife arm assembly. Its smooth, precision-machined surface and optimized structural design minimize friction between the roller and knife arm components, reducing wear and preventing abnormal noise during operation. The roller’s compact structure (25.4mm outer diameter, 12.7mm length) is tailored to the BC5060/BC5070’s internal layout, avoiding interference with surrounding parts like the grain conveying channel and bale forming mechanism.

Dimensions

 Manufactured to New Holland factory standards, the knife arm roller supports direct replacement without the need for modification to the baler’s knife arm mounting brackets or assembly interfaces. Its 25.4mm outer diameter and 12.7mm length are CNC-machined to tight tolerances (±0.05mm), ensuring accurate fitment with the knife arm’s bearing seats and guide rails. All contact surfaces are polished to a high finish, eliminating gaps that could cause unstable movement or premature component wear.

Load Capacity

Constructed from high-strength alloy steel with a hardened surface treatment (HRC 50-55), the knife arm roller is built to endure continuous load-bearing and friction during long-duration baling operations. It can withstand radial loads of up to 500N, resist impact from hay/straw clumps, and maintain structural integrity under temperature variations from -15°C to 65°C. The roller’s internal bearing (where applicable) features sealed design to prevent dust and chaff intrusion, ensuring smooth rotation even in dusty, debris-filled field environments.

Excellent Cost-Effectiveness

As a direct factory supplier, we offer this knife arm roller at OEM-quality standards with more competitive pricing. Every unit undergoes strict quality inspections before leaving the factory—including dimensional checks, surface hardness testing, and rotation smoothness verification—ensuring no compromise on performance or durability. Our roller provides a smart, budget-friendly alternative to original New Holland OEM components, ideal for reducing baler maintenance costs while ensuring reliable knife arm operation and protecting overall baler efficiency.
